Walther Trowal cuts processing times for finishing of blisks from several days to a few hours

Surface finishing of components for the aerospace industry

Walther Trowal cuts processing times for finishing of blisks from several days to a few hours

The work bowl of the “CM” rotary vibrator.

For the efficient surface finishing of high value work pieces like blisks for airplane and land based turbines, Walther Trowal has redesigned its CM vibratory system. It ensures that the work pieces receive a uniform, homogeneous high quality finish with absolutely repeatable results.

The surface finish of blisks („Blade Integrated Disks“) in airplane and other turbines affects to a large extent the airflow characteristics and, thus, the overall efficiency, fuel consumption and noise emissions.

To date the surface finishing of blisks was done manually with grinding disks and other manually operated tools. Due to the „human factor“ the quality of the final finish could greatly vary between work pieces. Frequently, it could even happen that certain surface areas were not finished at all.

For the consistent and high quality finishing of circular high value components Walther Trowal redesigned the rotary vibrator „CM“ in close cooperation with leading turbine manufacturers to make it more suitable for treating all kinds of turbine components.

The „CM“ system allows deburring and general surface improvement of components with diameters of up to 980 mm.

Single work pieces are mounted to the inner dome of the processing bowl. The height of the inner dome itself has been drastically shortened. After grinding media has been filled into the bowl, a vibratory motor causes the complete work bowl to vibrate. This causes a constant „rubbing“ of the media against the fixed work piece. Since the „rubbing“ action is highly homogeneous, a uniform, even finish on all surface areas of the disk and blades is achieved. After completion of the process the surface roughness readings amount to Ra = 0.2 to 0.4 µm.

Starting with an initial surface roughness of Ra = 4 to 5 µm, the desired finishing results are achieved within about five to six hours. Compared to this innovative method the manual finishing of blisks can take several days.

Christoph Cruse, sales manager at Walther Trowal, is commenting on the special conditions prevailing in the aerospace industry: „Especially for the production of turbine components any manual manufacturing operations must be viewed with great skepticism, because the quality of the work will vary greatly. With our new finishing machine we have completely eliminated the vagaries of the human factor. And, we can reduce the finishing times for blisks from several days to just a few hours“.

For finishing of blisks Walther Trowal is recommending the special finishing media, type V 2030. This media produces very smooth surface finishes on materials and shapes, which are typical for blisks. Of course, the V 2030 media is globally approved for the aerospace industry.

NEW UV LED SYSTEM SEMRAY® REVOLITIONIZES INDUSTRIAL CURING PROCESSES

The new UV LED solution Semray® sets new standards in production flexibility and efficiency with it Plug & Play concept and powerful technologies.

NEW UV LED SYSTEM SEMRAY® REVOLITIONIZES INDUSTRIAL CURING PROCESSES

Heraeus Noblelight revolutionizes the UV LED market with Semray®.

UV specialist Heraeus Noblelight has developed an innovative UV LED solution for industrial curing processes. The new UV LED system is designed around a unique Plug & Play concept for easy handling together with cooling systems and micro-optics that boost performance for optimal curing results. By minimizing the stray light the LED chip can be used more effectively and efficiently for precise curing in a variety of applications. Up to 30 percent faster curing times and significantly higher working distances can be achieved.

„Today, it is even more important to make production processes more efficient and time saving whilst still delivering brilliant results. That is why we have developed Semray®, a functional and multifaceted system, which fulfills these requirements and is easy to handle and integrate“, explains Dr. Michael Peil, one of the „UV LED pioneers“ at Heraeus who is responsible for the global sales of UV LED solutions.

Gathering energy for more flexibility
The formula is very simple: more UV LED chips built into the unit means more power. However, what sounds easy on paper is difficult to put into practice because space is limited. The challenge is to generate as much UV output as possible in the smallest possible area while, at the same time, keeping heat build-up low. Semray® features what are known as
micro-optics that gather UV radiation and reduce stray light to a minimum. In this way, up to 30 percent more UV energy reaches the product, resulting in extremely high and constant UV output which optimizes the curing process, and delivers the same excellent quality even at large distances or high production speeds.

Plug & Play makes complexity simple
Conventional UV LED systems are permanently installed in production processes. For servicing or in the event of a malfunction, the entire system needs to be dismantled. This costs time and money. Semray® solves this problem with its Plug & Play technology. Its backplane concept allows the easy installation and removal of UV LED segments. The UV LED segments can be replaced without the use of tools; no data or power supply cables need to be disconnected, because each backplane has just one data and power supply cable. This significantly minimizes downtimes, thereby saving time and money, increasing productivity, and making integration of the system into the plant considerably easier. The easy exchange of the segments and LED chips enables the user, at very low investment costs, to keep current technology standards or even change UV wavelengths.

From the most modern UV LED production facility in Europe
Semray® is developed and produced in the recently opened production facility, at the Heraeus headquarter in Hanau. It is the most modern UV LED module production facility within Europe. The production was designed based on the latest lean and quality standards, including clean-room technology with class ISO 14644-1 / ISO class 4. The professional manufacturing infrastructure and the chip-on-board (COB) line, contribute to a high production volume. Additionally the location allows best access to high-quality materials from the Heraeus technology group.

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.

Heraeus Carbon Infrared Oven Improves Powder Coating Flexibility and Quality at SFS Intec

Heraeus Carbon Infrared Oven Improves Powder Coating Flexibility and Quality at SFS Intec

Medium wave infrared radiation is readily absorbed by powder coatings and allows rapid and efficient curing.

A three-zone, carbon infrared medium wave oven from Heraeus Noblelight is helping SFS Intec to improve the flexibility and quality of its powder coating operations.

It has allowed the Leeds-based company to change powder curing from a continuous to a batch operation, so that it can now respond more quickly to customer requirements for corrosion-resistant screws and fasteners. In addition, the new pyrometer-controlled oven delivers a more consistent coating quality, is much more energy-efficient than the previous powder coating curing installation and requires considerably less space.

SFS Intec is part of a Swiss-owned international group, which is involved in a range of activities, from the manufacture of solar fastenings to hinge systems. The Leeds site, which has produced fasteners for over 100 years, today develops and manufactures stamped parts and supplies multifunctional thread rolling screws and sub-assemblies for use in the construction industry. It has the resource to offer architects, designers consulting engineers and contractors a proven commitment to effective technical solutions and efficient and responsive service.
Screw fasteners for the construction industry represent an important product line at SFS Intec. The heads of these screws must be coated to resist corrosion in use and the powder coating was formerly cured using an electrically-heated oven, through which the screws were passed continuously on a conveyor belt. However, this was very energy-intensive, as the oven had first to be heated up to temperature and then held at that curing temperature for some time. More importantly, this continuous operation lacked flexibility as it could not respond quickly to changes in color or to customer demands for fast delivery of limited numbers of screws, as often happens in the construction sector, especially in the closing stages of a construction contract.
To solve both of these problems, SFS Intec contacted Heraeus, who designed, manufactured and installed a carbon infrared medium wave curing system. This is a three-zone oven with seven 4kW medium wave infrared emitters in each zone. Medium wave radiation is readily absorbed by powder coatings and allows rapid and efficient curing.
In operation, trays of coated screws are now manually loaded into a selected zone and the emitters are switched on. The curing temperature of 180°C, monitored by an integral pyrometer, is achieved in a matter of seconds, rather than the 30 minutes or so required by the previous system, and a digital timer is then set to determine the time that the screws need to be held at the curing temperature. All three zones are individually loaded and controlled so that three different batches of screws can be cured simultaneously, if required.
„We very much pride ourselves on the quality of our customer service,“ says Bob Mrozik, the technical services manager at SFS, „and the new batch processing with the infrared oven now means we have improved this service by being able to respond more quickly to last minute customer requests – and often provide a next-day service. In addition, we have found that the pyrometer control of the product surface temperature, as opposed to merely controlling the oven air temperature, as was previously the case, has given a much more consistent quality cure.“

The Competence in Specialty Light Sources for printing systems

The Competence in Specialty Light Sources for printing systems

After retrofitting Heraeus carbon infrared (CIR) emitters in place of an NIR infrared print drying system, the Alito Color Group has been able to realise the full potential of its high speed print heads, by increasing sheet feed speeds to match the print

Special and personalized printing processes need special treatment. The ink of ink jet or laser printers need to be completely dried or cured before the printed sheets are passed on for subsequent operations such as stacking, cutting, folding or gluing. Infrared or UV technology is used for drying and curing, depending on the type of ink. Heraeus Noblelight presents its manufacturing competence in specialty light sources and systems for printing systems at Fespa 2012, in Barcelona, Spain. Learn more about infrared emitters, UV replacement lamps and systems and latest UV LED systems at Hall 3, stand N51.

Nowadays, people especially care about the usage of energy resources. That is why it is well worth the effort to examine industrial processes, to examine printing processes scrupulously and find techniques which offer the best results at the greatest possible economical and energy efficiency.

Infrared emitters improve energy efficiency
The Alito Color Group of Leyton, London achieved significant benefits through one simple change: They replaced their existing drier, which was fitted with near infrared (NIR), short wave emitters, with a Heraeus Carbon Infrared (CIR) System. Carbon Infrared (CIR) emitters from Heraeus Noblelight are especially efficient at drying water based inkjet inks. This is due to the medium wave infrared radiation, which the carbon emitters transfer into the inks at high power. Medium wave infrared radiation is absorbed extremely well by water-based inks. Carbon emitters combine high power and fast response times with the effective medium wavelengths.
Following successful tests, two carbon infrared (CIR) were fitted in the existing drier frame. Each 24kW module matches a special 4¼ inch print head. As a result, it is now possible to realise the complete capability of the high speed print heads. Practical usage has shown that the print quality can be maintained even at the high print speeds. In addition, the new emitters require less energy than before and have a significantly longer operating life. This has greatly improved the machine energy efficiency.

UV lamps and cartridges for efficient replacement
The emission spectrum of UV radiation is very important for the curing process. It must cause as many photons as possible to react with the coating, on one hand to cure the material completely and on the other to bind the coating with the substrate. Consequently, every curing process is complex and each coating system specifies its own individual curing parameters.
For theses individual processes Heraeus develops a variety of customized UV lamps and replacement lamps. This has been made possible through close collaboration with OEM partners, advances in lamp production have been best realized with the aid of intelligent energy supply.
A very efficient way to replace lamps at the end of life in digital printing machines is to replace the entire lamp cartridge. Using the used cartridge with just a new lamp is a false economy. The reflector degrades with temperature and becomes less efficient. It is also difficult to maintain the original shape after the old lamp has been removed. A well reshaped reflector could lose 15% of the ultraviolet radiation destined for the ink. So it is obvious that the lamp will need to be replaced again very soon. Second the system contains windows made of a high silica quartz glass. This material has to be kept clean. A small amount of material on these windows will absorb a considerable amount of energy that should be drying ink, not heating up the system. Heraeus Amba offers both replacement components: the complete cartridge solution and quartz glass plates, which allows the customer to replace the entire optical system in the print head of little more than the cost of a replacement lamp.

Customized UV LEDs for an efficient curing process
With digital printing, where the lamp, together with the print head, moves over the surface of the print, every little saving in weight and size matters. Innovative UV LEDs have a small shape and allow great flexibility in styling. According to customer specifications Heraeus Noblelight develops UV LED systems matching the machine environment. The individual system components are assembled from a modular construction system. Different sizes of UV LED moduls and wavelengths can be realized. A special integrated micro-optics technology enables the beam to be shaped to optimally suit the working distance required.
As a result, almost every special UV LED solution can be manufactured.
The system package also includes all the associated peripheral components such as cooling, control and power supply.
An important factor governing the operating life of a UV LED is the fact that all components belonging to the system are harmonically matched to each other. With the usage of UV LEDs, energy is saved during the curing process, because LEDs instantly switch on and off. So energy is consumed only on demand, when it is needed, without impairment of the performance of the LEDs.
Heraeus Noblelight manufactures UV-LED modules and systems in a complete development and production line. LED chips are processed in so-called „chip-on-board“ technology and measured and tested in our in-house, accredited measurement laboratory. As a result, customer-specific system solutions can be assembled for an efficient curing process.

Schneller und besser – innovative Trocknungsanlagen für die Industrie

Die Trocknungssysteme Airgenex® und Drymex® von Harter trocknen Produkte aus der industriellen Fertigung und deren Abfallprodukte – Industrieschlämme.
Schneller und besser - innovative Trocknungsanlagen für die Industrie
Harter Oberflächen- und Umwelttechnik GmbH

Im September 1991 bezog der Firmengründer Roland Harter mit einer innovativen Idee und seiner hochmotivierten Mannschaft seine ersten Büro- und Fertigungsräume in Lindenberg im Allgäu. Die „Harter Oberflächen- und Umwelttechnik GmbH“ war gegründet. Aus seiner anfänglichen Idee industrielle Schlämme als Abfallprodukt zu trocknen wurde schnell mehr. Die von Harter entwickelten Drymex®-Schlammtrocknungsanlagen stießen auf dem Markt auf großes Interesse.

Wenige Jahre später machte sich die Harter-Mannschaft daran, dieses Trocknungsverfahren weiterzuentwickeln und für den Einsatz in Produktionsprozessen zu optimieren. Harter brachte das sogenannte Airgenex®-Trocknungsverfahren auf den Markt, das ebenfalls im Niedertemperaturbereich mit Wärmerückgewinnung im geschlossenen System arbeitet. So ging es mit der Erfolgsgeschichte von Harter weiter. Die Airgenex®-Trocknungstechnologie fand Einzug in viele Fertigungshallen, in denen die konventionelle Heißlufttrocknung bis dato Probleme bereitet hatte. Diese Art von Kondensationstrocknung war nicht nur schneller und besser, sondern verhalf den Betreibern zusätzlich zu enormen Energieeinsparungen.

Über 700 Trocknungsanlagen hat Harter bis heute überwiegend im deutschsprachigen Raum, aber auch in anderen europäischen Ländern und weltweit platziert. Heute ist Harter weiter auf Wachstumskurs. Im vergangenen Jahr wurde das neue Trocknungssystem AIRGENEX®med zum Einsatz in der Pharmaindustrie und in der Medizintechnik erfolgreich eingeführt. Über die Jahre wuchs das Unternehmen Harter zusehends und bezog im Jahr 2001 das jetzige Firmengelände in Stiefenhofen. Das Team von circa 30 Mitarbeitern wird heute von Mitinhaber und Geschäftsführer Reinhold Specht, dem Schwager des 1998 verstorbenen Roland Harter, in Zusammenarbeit mit Prokuristin Ursula Harter geleitet.
