The new generation of Trowal continuous shot blast machines is in operation

A Mexican manufacturer of automotive aluminum die-cast components now operates five continuous shot blast systems from Walther Trowal.

The new generation of Trowal continuous shot blast machines is in operation

The new THM troughed belt continuous shot blast machine equipped with turbines with curved throwing.

Walther Trowal has recently commissioned a THM troughed belt continuous shot blast machine for a customer in Mexico that is equipped with a brand new generation of blast turbines. These turbines were specifically designed for shot blasting of aluminum components. With a considerably higher blast media throwing speed the new turbines produce significantly shorter cycle times than the predecessor models.

The Mexican customer already operates very successfully four continuous Trowal shot blast machines. Because of their excellent performance he chose to purchase another THM machine, when he had to expand his production capacity.

Up-and-coming: Aluminum, the gentle blast media

The increasing sales trend at Walther Trowal indicates that ever more customers are switching to aluminum media when shot blasting aluminum components. Because of its lower bulk density aluminum media is a lot gentler than, for example, stainless steel shot. Typical automotive forgings made from aluminum are, for example, steering knuckles or swivel bearings. Aluminum die-castings processed in THM shot blast machines can be all kinds of housings, covers or levers.

Because of its lower density the impact energy of aluminum media on the work pieces is considerably lower compared to other blast media. To offset this limitation Walther Trowal developed turbines with curved throwing blades, which generate a significantly higher blast media throwing speed than straight blades. This, combined with the fact that in THM machines the turbines are located very close to the work pieces, and the media throughput is considerably higher, results in optimized energy utilization and surprisingly short cycle times. However, the shot blast treatment remains very gentle. In short, despite the relatively low density of aluminum blast media, the shot blast process is highly effective and at the same time surprisingly gentle preventing any warping or distortions of delicate work pieces.

Another benefit of aluminum blast media is that it reduces the wear rate in the turbines and the machine to a fraction of the wear caused by steel shot, resulting in higher uptimes and lower operating costs.

Walther Trowal offers a range of different machine sizes equipped with up to four turbines. For example, for forged aluminum components the new THM 700/4/E with 4 turbines and a power of 15 kW for each turbine, produces an exceptionally high degree of productivity.

Specifically designed for handling aluminum media

To meet all the challenges posed by aluminum shot the Trowal engineers redesigned many machine assemblies, among them the media dosing system and the turbines. One detail of many: A rough surface of the throwing blades would quickly destroy the aluminum particles. Therefore, Walther Trowal is smoothing the blade surface with in-house vibratory finishing equipment. The result: A greatly reduced blast media consumption, lower dust emissions and significantly improved turbine uptimes.

Gentle work piece transport

THM troughed belt continuous shot blast machines are equally well suited for treating mass-produced bulk parts or large, delicate components. Especially with delicate, somewhat fragile work pieces the THM concept offers significant advantages: In these systems the work pieces are evenly distributed through the entire machine length. This results in a very gentle transport and prevents intensive part-on-part collisions. And the fact that the transport rods are covered with a relatively soft PU further cushions the already gentle tumbling action. This is particularly important for fragile components with thin walls, allowing them to be discharged from the machine without any nicking or other damage.

No problem with older THM systems!

When developing the new turbines Walther Trowal also took into consideration the many older machines still in operation: Any THM customer who wants to take advantage of the new turbines can easily install them in his existing machine(s). This allows the customers to increase the efficiency of their shot blast operation with minimal costs.
For THM systems still requiring steel or stainless steel blast media, Walther Trowal supplies the new turbines with the curved throwing blades made from tool steel also offering significantly higher turbine uptimes.

Walther Trowal: A new era for high gloss polishing of ceramic surfaces

Vibratory finishing of ceramic components: Perfect surface finishes at surprisingly low costs

Walther Trowal: A new era for high gloss polishing of ceramic surfaces

The new polishing paste PKC is also suitable for finishing orthopedic implants.

The recently developed polishing paste trowapast PKC produces flawless mirror finishes on ceramic work pieces with surface roughness readings of ra = 0.002 – 0.005 µm. These are values, which to date could only be achieved with costly manual polishing. The new finishing process opens entirely new surface finishing possibilities in the fields of decorative ceramics and medical engineering.

Mechanical high gloss polishing on metallic work pieces has been around for many years. To date similar finishes on ceramic components were considered as impossible.

But, because they offer a substantially higher wear resistance compared to metal alloys, the significance of ceramic materials has been growing steadily. When it comes to designer, optical and consumer products, high luster finishes are a key element for their market acceptance. But smooth, shiny surfaces also have a functional dimension for components requiring low frictional resistance. Ceramics made from zirconium provide the required hardness, but smoothing and polishing them by mechanical means was so far an unsolved problem.

Generally, mass finishing is a cost effective method for polishing of a variety of work pieces. The process usually starts out with an aggressive grinding powder followed by a polishing paste that creates a high luster on the work pieces. These polishing pastes contain extremely fine abrasive particles. Unfortunately, on very hard surfaces their material removal rate is often insufficient. For instance, creating a surface reading of ra = 0.02 µm would take such a long time that it would be absolutely uneconomical.

Walther Trowal offers a range of polishing pastes or powders containing minerals with different hardness values and initial grain sizes allowing a wide spectrum of polishing applications on all kinds of materials.

The secret: Sharp edges are becoming rounded

A suitable paste product for the economical polishing of ceramic had yet to be developed. Since for several industrial sectors in recent years this challenge had become more urgent, in 2012, a cooperative of eight companies and research institutes, among them Walther Trowal, was organized with the goal to develop a process for high gloss polishing of ceramics. The project, named KeraOpt, was financially supported by the „NRW-EU-Ziel 2“ fund for industrial research.

Within the group Walther Trowal assumed the task of developing a mass finishing process that allows creating the desired high gloss polishes on ceramic work pieces in a cost effective manner.

Another project of KeraOpt was the development of ceramic inlays for injection molds that produce very fine geometrical structures combined with extremely smooth surfaces.

After comprehensive test trials Walther Trowal could identify a mineral that is suitable for these kinds of applications: Besides producing high gloss polishes on metallic components, it also produces the same type of finish on zirconium ceramics. With the new polishing paste trowapast PKC Walther Trowal has at last a product that can successfully be used for high gloss polishing of all kinds of ceramic components.

The new polishing paste contains a mineral with a relatively large grain size with an initially very high grinding effect. During the process the mineral grains wear down to smaller sizes transforming the process from intensive grinding to fine polishing.

Angelika Helten, managing the chemical lab at Walther Trowal, explains why the new paste is so effective for polishing ceramic components: „The secret is that the PKC paste is changing its technical characteristics during the course of the finishing process. While conventional mineral grains are breaking up into smaller grains with sharp edges, the new minerals are becoming rounded. Expressed simply, they do not create micro scratches on the surface but truly polish, thus producing very shiny surfaces. The result, with surface readings of ra = 0.002 to 0.005 µm, has even surprised us.“

For the ceramic mold inserts mentioned above the same approach was taken that had proven so successful for polishing metallic surfaces. Since the removal rate on ceramic is lower than that on metal, the process lasts longer and requires two different ingredients. With an initial surface roughness of ra = 0.3 µm the first stage with a grinding powder takes about 20 hours. This is followed by a second stage with trowapast PKC that lasts about 40 hours.

The result: A member company in the KeraOpt cooperative now produces the mold inlays for plastic injection molding no longer with tool steel but with ceramic. The surface readings could be reduced from ra = 0.011 to 0.002 µm.

A real success story

Another member of the cooperative is also utilizing the new polishing technology. This company produces decorative components used in the interior of vehicles, for example, gear shifters and control elements for car radios and air conditioners.

All these components, for which the final customer demanded high gloss polishes, consist of zirconium ceramics. To date these parts had to be manually polished. Now, with trowapast PKC they can be mechanically polished with a fully automatic process.

The ceramic components undergo a 72-hour grinding process followed by a 48 hour polishing step and 2 hours for the final brightening. This results in absolutely scratch-free work pieces, which after a subsequent cleaning process can be directly installed.

Christoph Cruse, the general sales manager at Walther Trowal, sees significant advantages for the customers: „The duration of the finishing process may appear very long. But it takes place without any supervision and requires a minimum of operator intervention. Since the new process allows the treatment of batches of 5,000 pieces, the costs per piece a re significantly lower than before.

New possibilities

First feedback from the customers indicates that the new polishing process represents a significant progress towards creating smooth, shiny surfaces on ceramic components. It opens a brand new field of new applications, for example for producing
-Thread guiding parts for textile machinery
-Ceramic coatings of metallic components
-Orthopedic implants
-Components for optical electronics
-Mirrors

Walther Trowal offers interested companies to test the new technology at the Trowal test lab in Haan. This ensures that the technical specifications of potential users are met, before they have to make a purchase decision.

Since 1931 Walther Trowal is developing and producing modular as well as custom engineered solutions for a wide range of surface finishing applications.

Initially only making vibratory finishing equipment, over the years Walther Trowal has continuously broadened its product range and today offers a wide portfolio of equipment and services for improving all kinds of surfaces, e.g. mass finishing, part cleaning, shot blasting and drying of a wide spectrum of work pieces, last but not least, the coating of mass produced small parts.

Trendsetter & Wachstumschance: IT-Miete

IT-Komplettpakete mieten statt kaufen – am Beispiel der Solutive AG

Trendsetter & Wachstumschance: IT-Miete

Erfolg bringt Wachstum, Wachstum bringt Erfolg: Da Unternehmen – gerade bei starkem Personalwachstum – immer auf die Kosten achten müssen, setzte die Solutive AG aus der Nähe von Hockenheim bei der Ausstattung der rasch auf 30 angewachsenen digitalen Arbeitsplätze zunächst auf moderne, aber günstige PC-Modelle unterschiedlicher Anbieter. Die unterschiedliche Hardware brachte allerdings schnell Probleme mit sich, die Solutive wertvolle Zeit und Ressourcen raubten. So musste jedes neue Endgerät für die Freischaltung der Garantielaufzeit mühevoll selbst registriert werden. Die interne Verwaltung und auch das Einrichten neuer Arbeitsplätze waren mit großem Aufwand verbunden. Bei Ausfällen musste aufgrund der unterschiedlichen Gerätehersteller, Kaufzeiträume und Garantielaufzeiten jeweils langwierig geprüft werden, ob noch Garantie bestand, wer für die Reparatur zuständig war und mit welchem Gerät der Mitarbeiter in der Zwischenzeit weiterarbeiten sollte. Denn eine Reparaturphase und zur Untätigkeit verdammte Mitarbeiter verursachen Produktivitätsminderungen. „Manche Arbeitsplätze hatten bis zu drei Docking-Stationen, weil wir Hardware verschiedener Hersteller bezogen hatten“, beschreibt Solutive-Vorstand Tobias Moosherr die ungute Ausgangslage. Kurz: Der stark durchmischte Gerätepool wurde zum echten Kopfschmerz- und Kostenfaktor.

Da man alle Kapazitäten und das Kreativpotenzial für den Ausbau des Kerngeschäftes und nicht für das leidige Herumschlagen mit IT-Mängeln einsetzen wollte, entschied sich Solutive, in Sachen Hardware einen Neustart-Knopf zu drücken – und zwar zusammen mit dem IT-Systemhaus Aluxo. Aluxo vereinheitlicht nun die Hardware-Basis, indem jeder alte oder ausfallende Arbeitsrechner sukzessive mit Surface Pro 4 oder dem Surface Book ersetzt wird. Doch nicht in Form gekaufter Hardware, sondern durch gemietete Geräte. „Workplace as a Service“ heißt dieses neue Angebot, beim dem der Distributor ALSO Deutschland GmbH die Miete von individuell konfigurierbaren Hard- und Softwarepaketen ermöglicht. Marcus Rieck, Geschäftsführer der Aluxo IT GmbH kommentiert zufrieden: „Durch die reibungslose Zusammenarbeit mit dem Distributor ALSO war es uns möglich, erste Geräte schon binnen 48 Stunden auszuliefern.“

Essentiell am Workplace as a Service-Paket ist, dass Versicherung und Garantie im Rahmen eines Schutzbriefes enthalten sind. Falls ein Gerät beschädigt werden sollte, gestohlen wird oder schlichtweg nicht mehr funktioniert, kümmert sich ALSO binnen 24 Stunden um den Austausch. Und durch die Speicherung der Daten in der Cloud sind die Firmendaten stets gesichert und der Austausch eines Geräts ändert nichts an deren Verfügbarkeit. Neuen Mitarbeitern kann umgehend ein moderner digitaler Arbeitsplatz bereitgestellt werden, eine E-Mail an Aluxo und eine Unterschrift unter den Mietvertrag reichen aus. Optional kann Aluxo den Arbeitsplatz auch bereits im Vorfeld installieren.

Auch finanziell rechnet es sich, die Geräte zu mieten, teilweise hat man einen Preisvorteil von bis zu 30% im Vergleich zum Kauf. Dazu kommt zu vergünstigten Konditionen das Office 365-Paket, das alle produktiven Werkzeuge für die tägliche Arbeit enthält. Die Geräte müssen auch nicht langjährig abgeschrieben werden und sind vollständig steuerlich als Betriebsausgabe absetzbar.

Die Beschäftigten sind begeistert, von nun an mit der neuesten Hard- und Software flexibel arbeiten zu können und auch die Kunden der Solutive AG sind von den leistungsstarken und schicken Geräten beeindruckt. „Durch die Nutzung von Workplace as a Service lösen sich alle Probleme in Wohlgefallen auf: eine Geräteklasse für alle Mitarbeiter, Vor-Ort-Austausch für jedes Gerät und ein toller Service von Aluxo“, zeigt sich Tobias Moosherr vollauf zufrieden. Ein innovatives und wendiges Unternehmen wie die Solutive AG passt eben einfach perfekt zum modernen und innovativen IT-Mietmodell!

Trend IT-Leasing

Flexibel, sicher, clever: Hard- und Software lieber mieten statt kaufen!

Trend IT-Leasing

Nicht nur das täglich genutzte Fortbewegungsmittel auf vier Rädern, sondern auch die IT sollte modern, schnell, sicher und komfortabel in der Bedienung sein – und ultramobil. Schließlich kann man heute nicht mehr nur ausschließlich vom Schreibtisch aus arbeiten. Die Daten sollen rundum geschützt vor Fremdzugriffen genau da verfügbar sein, wo man sie braucht, ob im Büro, zu Hause oder unterwegs.

Wenn bislang gerade kleine und mittelständische Unternehmer den Gesamtaufwand für die Anschaffung neuer Hardware und einer modernen Infrastrukturlösung fürchteten und Investitionen immer wieder aufschoben, bietet nun das neue Modell „Workplace as a Service“ (WaaS) schon kleineren Firmenkunden die Möglichkeit, die eigenen Arbeitsplätze mit individuell konfigurierbaren Paketen aus aktuellster Hard- und Software auszustatten. Durch den IT-Mietservice, den Microsoft aktuell über Partner und den Distributor ALSO anbietet, profitieren Unternehmen durch eine stets aktuelle IT, eine geringere Kapitalbindung sowie planbarere Kosten und weniger Unterhaltungsaufwand durch einen ausgelagerten Service.

„Mit WaaS brechen wir den Investitionsstau auf. Die Bereitschaft, auf das Mietmodell umzuswitchen ist sehr hoch“, erklärt Malte Wigger, Leiter der Workplace as a Service Business Unit bei der ALSO Deutschland GmbH und führt fort: „Die Kosten sind überschaubarer und vor allem planbar!“

Der WaaS-Service funktioniert sogar noch besser bzw. schneller als eine Vollkasko beim PKW – ein verlorenes, kaputtes oder gar gestohlenes Gerät wird binnen 24 Stunden ausgetauscht! Auch in Sachen Budget überzeugt WaaS: Die Leasinggebühr eines Gesamtpakets aus Microsoft Surface inkl. Programmen und IT-Infrastruktur beträgt gerade einmal 50,95 EUR pro Monat und Benutzer (Beispielkalkulation für Surface Pro 4 inkl. Type Cover, Surface Dock und Office 365 Business).

Wer weiß besser als Mobilitätsprofis, dass mieten statt kaufen eine gute Chance für die kontinuierliche Modernisierung eines Unternehmens bietet? Mehr Infos unter www.microsoft.de/workplace-as-a-service

Ein gallisches Dorf in Sachen Digitalisierung

IT-Migration mal anders: Modernste Hardware, aktuelle Software, super Services zur Miete statt Kauf!

Ein gallisches Dorf in Sachen Digitalisierung

(Bildquelle: @Microsoft)

Wir schreiben das Jahr 2016 nach Christus. Ganz Deutschland diskutiert über Digitalisierung… Ganz Deutschland? Nein! Die Werbeschmiede Calendarium aus dem kleinen Ort Hörselberg-Hainich in Thüringen hat den Schritt in die digitale Zukunft längst gewagt und setzt auf vernetztes Arbeiten mit Mietpaketen aus Hardware, Software und Services in Form von „Workplace as a Service“.

Es war einmal…
Der Wunsch, modern, allzeit vernetzt, zu jeder Zeit an jedem Ort zu arbeiten, wurde lange schon gehegt, allein es fehlte das Kapital, das rund 50 Köpfe starke Unternehmen in die digitale Zukunft zu bringen. Dabei braucht Kreativität – die Schlüsseltugend der Calendarium Promotion GmbH – Kommunikation und Kollaboration. Doch eine veraltete IT-Ausstattung ließ Wissen, Expertise oder kreative Skizzen in den Mailboxen einzelner Mitarbeiter eingehen, kreative Ideen von Kollegen außerhalb der Teams konnten nicht einbezogen werden, da starre Arbeitsplatzstrukturen Zusammenarbeit und digitale Teamarbeit behinderten. Die fortschreitende Nutzung privater Tools brachte das brüchige System dann endgültig fast zum Einsturz. Die Geschäftsführung sah ein, dass die veraltete IT die Kreativität im Unternehmen wie ein schwerer Hinkelstein beschwerte.

Alle Wege führen nach…
Für Calendarium war der Druide, der die nötigen Zutaten kannte, die B-S-S Business Software Solutions GmbH mit Sitz in Eisenach und Dresden, die ab April 2016 die Unternehmens-IT auf den neuesten Stand brachte. Die Transformationsexperten unterstützen mittelständische Unternehmen beim Finden der für sie passenden Digitalisierungsstrategie und bei der schrittweisen Einführung optimierter Arbeitsweisen und digitaler Arbeitswerkzeuge. Im Falle von Calendarium waren das Windows 10, Office 365 und die von der B-S-S entwickelte Ergänzung dazu, die NEUARBEITEN digitale Projektplattform, sowie Microsoft Surface als Workplace as a Service – Mietmodell statt Neuanschaffung also.

Kosten senken, Kreativität steigern!
Durch die neue Plattform ließen sich Kommunikations- und Zusammenarbeitsdienste beliebig kombinieren, Plattform- und Standort-unabhängige Arbeit wurde ermöglicht. Auch die Handhabung wurde massiv vereinfacht – schließlich konnten die Mitarbeiter alle Dienste mit denselben Nutzerdaten erreichen. Eine integrierte Suche über alle Inhalte hinweg wurde zur zentralen Informationsquelle. B-S-S Produktmanager Thomas Müller bringt das Ergebnis auf den Punkt: „Workplace as a Service bietet umfassende, schnell und kostengünstig einsatzbereite Arbeitsplattformen. Für uns eine wichtige Grundlage, um uns mit unseren Kunden auf die Transformation ihres Geschäftes anstatt ihrer IT zu konzentrieren.“

Moderne Geräte pushen Produktivität und Kreativität
„Der Anwender wünscht sich, dass seine Hardware funktioniert, dass sie seine Arbeit optimal unterstützt und ihm Spaß macht, dass man sich also freut, wenn man seine IT bedient. Viele äußern den Wunsch nach einem modernen Gerät zum Arbeiten. Dies wird oft unterschätzt, denn wenn man mit einem modernen Gerät und einer funktionellen Infrastruktur arbeitet, fördert das die Motivation. Und wer motiviert arbeitet, arbeitet eindeutig produktiver“, so Frank Maenz, Marketing Manager Kleinunternehmen und Mittelstand bei der Microsoft Deutschland GmbH.

Aluminum components require soft, less abrasive blast media

New blast turbines with curved throwing blades reduce cycle times.

Aluminum components require soft, less abrasive blast media

The troughed belt continuous feed shot blast machines, type THM, with curved throwing blades reduce

At the Aluminium 2016 trade show Walther Trowal introduces a new generation of blast turbines for the troughed belt continuous feed shot blast machines, type THM. These turbines increase the throwing speed and, thus, reduce cycle times for shot blasting of light metals like aluminum and magnesium. For weight reasons these two metals are increasingly replacing components, which to date were made from steel. However, shot blast applications for aluminum and magnesium frequently require soft, less abrasive blast media like, for example, aluminum shot.

When it comes to shot blasting die-castings or forged components made from aluminum and magnesium, but also zinc, many users are switching to somewhat softer aluminum blast media. Yet, because of their lower bulk density the impact energy of these media is significantly lower compared to other media like steel shot. For this reason, Walther Trowal recently developed turbines with curved throwing blades, which generate significantly higher throwing speeds.

In addition to higher throwing speeds, the new turbines also allow a much higher media throughput. Despite the lower media bulk weight of these „soft“ blast media the results are shorter cycle times an, at the same time, greatly improved surface finishes.

Since the throwing blades in the new turbines are curved on both sides, the turbines can be run in two directions.

For applications requiring steel and stainless steel blast media, Walther Trowal offers the curved throwing blades in wear resistant tool steel. This increases the overall blade uptimes significantly.

The first machine equipped with the new turbines will be delivered to a customer shortly. Of course, existing THM machines can be easily equipped with the curved blade turbines allowing the users to increase productivity and reduce their costs.

Hall 12 / Booth G 50

Background:

Troughed belt continuous feed shot blast machines: Extremely gentle work piece transport

The THM continuous troughed belt machines can handle large quantities of bulk produced small parts as well as large, delicate single work pieces with complex shapes. Because of the much simpler and gentler work piece handling they frequently replace conventional batch tumblast machines.

THM continuous feed machines are especially advantageous for treating very delicate components: Contrary to batch tumblast systems, where the parts are intensively tumbling over each other with a high risk of nicking, in the Walther Trowal THM machines the work pieces are spread out throughout the length of the trough, ensuring a gentle, nick-free processing. The work pieces are gently rolling over the transport rods coated with polyurethane. This gentle part transport is especially important for complex, thin-walled components requiring an intensive blast cleaning process. The results are perfectly cleaned parts without any nicking or other damage.

Compared to spinner hanger machines the THM continuous shot blast systems also offer significant technical advantages. Because the work pieces are gently tumbling through the tunnel formed by the troughed belt, they are exposed to the blast stream from all sides, with the distance between work pieces and turbines remaining constant. This ensures all around, perfect shot blasting results.

Aluminum: The gentle blast media

The blast cleaning and de-flashing of die-cast or forged aluminum components requires soft blast media. Typical forged parts are steering knuckles or swivel bearings. Aluminum die-castings processed in THM systems can be housings, covers, caps and levers.

But there is also an increasing trend towards utilizing magnesium die-castings, especially in the automobile industry. Many structural components, for example dashboard mountings, are made from magnesium. This material has not only a low weight, but also offers high tensile strength.

For shot blasting of these materials in THM machines aluminum media is becoming quite popular. Since the distance between the blast turbines and the work pieces is very small, the shot blast process is highly effective, even though the blast media has a low bulk density.

Walther Trowal: New rotary drum coater for work pieces that are heavy or have complex geometries

At the Paint Expo Walther Trowal presents the new R 80 Rotamat drum coater.

At the Paint Expo Walther Trowal presents the new R80 Rotamat for coating of mass-produced small parts made from plastic, metal, rubber and wood.

With a drum diameter of 800 mm and a usable volume of 50 l the new machine can accommodate batches of 50 kg. This is of particular interest to customers, who must coat parts with complex geometries or heavy parts, which, for example are made from metal.

With technical features like optimized fresh air inlet and a modular filter system – up to filter class F6 – this machine offers a high degree of flexibility regarding the use of different paints with, at the same time, a higher throughput. By being able to use more solvent the users can speed up the coating process and still remain within the ATEX limits.

First reports from the field indicate that the new coater so far has not only fully met but exceeded expectations.

By optimizing the airflow and the paint spraying system, Walther Trowal was able to keep overspray at an absolute minimum. And finally, the new heat control system helps reduce cycle times and energy consumption.

Improved grinding performance, excellent surface finishes and less media wear

A new high-density media combines the advantages of plastic and ceramic media in one product

Improved grinding performance, excellent surface finishes and less media wear

Finishing of die-castings in a CB 400 rotary vibrator from Walther Trowal.

With the newly developed fast cutting plastic media „trowalplast HDC“ Walther Trowal offers a product that is ideal for grinding and surface smoothing of metal work pieces, especially die-castings. The high density and sharp edges of the embedded abrasive material contribute to a drastic shortening of process times. But they also produce excellent surface finishes at a surprisingly low wear rate.

Walther Trowal has pioneered the development of the new HDC media (High Density Cut) and is now introducing it in the German market. This media consists of a plastic carrier filled with zirconium silicate, thus combining the advantages of lightweight plastic media with the extremely high density of the abrasive filler material. This combination yields metal removal rates that are comparable to ceramic media with, at the same time, a surprisingly low wear rate and excellent surface finishes.

Angelika Helten, head of the chemical lab at Walther Trowal, comments on the reasons for developing this new media type: „Many of our customers would love to work with ceramic media, because their finishing tasks require a high grinding performance. But ceramic media tends to chip and frequently wears relatively fast. That is why they are using plastic media, which produces the required finishing results, but at much longer processing times. Our new HDC media combines the advantages of plastic and ceramic and is, therefore, the ideal solution.“

An excellent application for the new HDC product is the finishing of die-castings, for which until now plastic media – for example the type „ET“ from Walther Trowal – has been used.

The HDC is equally effective in all types of mass finishing equipment. This applies to high-energy centrifugal disk finishing machines, which generally cause a very high wear rate of ceramic media, as well as to linear continuous feed vibratory systems, which only allow a relatively narrow band of processing times. Especially in these machines the HDC is particularly effective, because it produces significantly better finishing results at the prescribed cycle times.

Christoph Cruse, general sales manager at Walther Trowal, wants to make it easy and simple for the customers to test the new high density media: „Those customers who are already using our equipment can simply order a machine load of the new media and test it in their machine. For new customers, who consider investing in a mass finishing machine, we offer processing trials in our test lab free of charge.“

Improved grinding performance

Because of its relatively high bulk density and the sharp edges of the abrasive material the HDC offers grinding characteristics similar to ceramic media.

Besides the actual material content the media shape plays a significant role. While ceramic media are only available in relatively few shapes, the HDC can be produced in all the known shapes and sizes for plastic media. This allows Walther Trowal to offer media that are perfectly adapted to the different work piece shapes and sizes. Initially, the company will offer the HDC as 8 mm (0.3″) cones. This is the smallest size available on the market. And it is ideal for finishing work pieces with many internal corners and passages.

For the daily mass finishing operations the media color is also an advantage: Contrary to the mostly grey ceramic media the HDC with its pink color can be easily recognized in case of media lodging in the work pieces.

Lower wear rate

To date a high grinding performance automatically meant a high wear rate. With the HDC media this is different: Despite its high metal removal rate, in comparison to other fast cutting media in the Walther Trowal product range the high-density media is wearing relatively slowly.

No silica and alumina

The HDC media is filled with zirconium silicate. Besides the fact that the abrasive grains have exceptionally sharp edges, this abrasive has the added advantage that it does not contain any aluminum oxide or silicon dioxide. Therefore, it can be used for work pieces, which must not be in contact with these two materials. With the HDC Walther Trowal can now offer a range of fine grinding and fast cutting media that does not contain aluminum oxide.

Pixargus: Inspecting inspection systems

Optical surface inspection of profiles for the rubber industry: On-site calibration saves time and ensures reliable production along the entire process chain.

Pixargus: Inspecting inspection systems

The calibration unit has been designed for on-site use

Pixargus, leading manufacturer of inspection systems for profiles and tubings, is now offering on-site calibration services for Pixargus systems by means of a newly developed mobile calibration unit. The advantage for the customer is that the inspection system does not have to be removed from the production line and shipped to Pixargus but will be immediately ready for use after the calibration has been done.

More and more end customers insist on the implementation of automatic optical surface inspection in the production processes. Therefore, high precision and long-term reliability of the inspection systems have become increasingly important aspects for tubing and profile manufacturers, since these systems have meanwhile become an integral element of quality control in many works. This makes regular checks and calibration of these systems indispensible.

With the Pixargus inspection badge and the MSA certification, profile manufacturers can attest to their customers that the inline quality control systems in place work flawlessly and reliably.

The mobile calibration unit contains a certified calibration specimen with several boreholes, the distances and diameters of which have been precisely measured. As the surface inspection is based on line scan cameras, the specimen must be constantly in motion while being measured. Pixargus solved this requirement by means of a motorized traversing unit which constantly moves the specimen back and forth. Inspection systems may be equipped with up to eight cameras. In order to allow each individual camera to be tested, the specimen can be rotated while being clamped in the calibration unit.

During each test, the system captures 600 measurements per camera. Pixargus evaluates the data and makes them available to the operator. After completion of the evaluation process, the system will receive the new parameters, which can also be fed to the system via remote access from the Pixargus head office. The calibration guarantees the customer that surface defects of the profiles, if any, are detected at the correct positions and that their sizes are correctly measured.

Michael Frohn, Service Manager at Pixargus, has already successfully accomplished numerous onsite calibrations: „Pixargus is the first company in our industry to offer a mobile calibration service. It is no longer necessary to remove the systems from the production lines. The calibration is a matter of just a few hours and does not require any major preparations. Our customers particularly appreciate that they can call on us, for example, in case of a plant downtime scheduled at short notice.“

Dirk Broichhausen, Vice President Sales & Marketing at Pixargus, sees the mobile calibration service as part of the overall performance of the Pixargus inspection systems: „The quality requirements to be coped with along the entire process chain are becoming ever more exacting. Fewer and fewer operators are responsible for more and more plants and have to safeguard the plants“ process capability and the repeatability and stability of the processes. For us this means that it is no longer sufficient to react quickly and competently but that we must also be able to act preemptively. By „competently“ I understand that we do not have a run-of-the-mill call center but a hotline operated by a team of technicians and engineers who have direct access to the product management system and are capable of providing qualified answers to our customers“ questions – in real time.“

Walther Trowal: The rotary drum coating technology conquers the market

Homogeneous and energy saving coating of mass-produced small plastic and rubber components

Walther Trowal: The rotary drum coating technology conquers the market

Walther Trowal introduces the new Rotamat R80 at the DKT exhibition.

More and more customers are choosing the rotary drum technology for coating their mass-produced small plastic and rubber components. Within just a few years the sales of the Walther Trowal Rotamat coating systems have increased several fold. At the DKT/IRC 2015 the company is introducing its redesigned Rotamat R80, which compared to its predecessor model offers not only a higher operational flexibility but also a higher capacity for coating of plastic components.

For several months now Walther Trowal has noticed a distinct trend towards the use of rotary drum coaters for the coating and painting of small mass-produced components. Many small-part manufacturers are switching from the drum coating at room temperature to the hot air drum coating technology. Other manufacturers are no longer subcontracting their coating work to external service companies but do it in-house with Rotamat systems. And some have replaced their single-piece paint systems with rotary hot air drum coaters.

With the drum coating method the small parts no longer have to be individually placed on special racks but can be loaded into the Rotamat drum in relatively large batch sizes. This technology is ideally suited for treating small parts made from different plastic materials like elastomers, ABS, PC or PS. Water based as well as solvent based paints can be processed.

Building on the success of the predecessor models Walther Trowal completely revamped the Rotamat range, and with the R80 is introducing a machine that can be even better adapted to the individual requirements of the users. The modular filtering system allows not only cleaning the exhaust air up to filter class F6, but it also allows spraying more solvent based paint, offering a higher part throughput without jeopardizing compliance with the prevailing clean air standards.

Frank Siegel, the sales manager for coating technology at Walther Trowal, explains, why the sales of Trowal coating systems are continuously increasing: „Since the Rotamat was introduced, we have sold nearly 300 units. The increased machine bookings we have seen during the past few months are mainly due to the fact that many small-part manufacturers are bringing their coating work back in-house to reduce their costs and, at the same time, improve their quality.“

Many new technical features!

The new Rotamat R80 from Walther Trowal has a drum diameter of 800 mm and can handle about 50 kg of parts with a batch volume of 50 liters. This batch size meets the requirements of many customers who must coat delicate, complex shaped parts or are processing relatively heavy parts like metal components. The new R80 is also available with a drum that offers a diameter of 700 mm and a usable part volume of 30 liters.

The airflow and the paint application system were optimized to a point where only a very small amount of overspray is created.

The inside of the coating drum is equipped with an explosion protected LED light allowing precise observation of the coating process, be it the paint layer buildup or color changes.

The new heating control system helps reduce cycle times and energy consumption. A PID controller adjusts the inlet air temperature in relation to the work piece temperature. At the same time it takes into consideration the actual air volume. The new controller reacts extremely quickly. This quick reaction and the better insulation of the drum allowed reducing the electrical energy requirements to 9 kW.

Air filtration

With the new exhaust air filter unit Walther Trowal managed to greatly enhance the possibility for using different paints. This is an important feature for those customers who must coat a large variety of parts with different types of paint. The R80 offers four independently usable stages for filtering the exhaust air so that the particle sizes caught by the filter system can vary within a relatively large range up to filter class F6.

The new filter unit also contributes to a higher part throughput: The user can now use more solvent, thus, speed up the coating process and still meet the standards for the maximum solvent concentration at the work place.

Another important feature of the new filtration system is the secondary air system that allows the connection to a thermal post combustion installation, which may be already available at the customers. The secondary air system limits the air volume pulled by the thermal post combustion installation so that the coating process is not affected.
