Strategic cooperation between Georg and Güdel Group

Transformer core production on the way to industry 4.0 / IoT

Strategic cooperation between Georg and Güdel Group

The development of an offline e-stacking solution for automatic stacking of transformer cores.

Heinrich Georg Maschinenfabrik and Güdel Group AG concluded a cooperation agreement for the collaborative development of lines for the automatic stacking of transformer cores. GEORG brings in their know-how in the plant engineering field, Güdel the robot technique for the automatic stacking of the laminations. That way, systems are constructed in the future that speed up the production of transformers, reduce manual time and enable a higher production flexibility. Furthermore, the intensive data transfer prepares the ground for industry 4.0 / IoT.

GEORG is leading in the manufacture of production lines for the transformer industry and already has own automation solutions. However, for the manufacture of power and big distribution transformers of up to several hundred tons, many GEORG customer often still stack the individual laminations for the transformer cores manually which is very time consuming. The potential of modern handling systems and the networking of data often remains unused so far. Especially for offline systems, there are only few highly automated systems.

On the basis of their gantry robot, Güdel has already developed an automatic core stacking system for transformers in the 50 kg to 350 tons weight range which was put into operation at a leading European transformer manufacturer. The in-house manufactured gantry robots do not require any external centering units thanks to their high positioning accuracy and repeatability and thus reach significantly lower production times.

With their leading technologies, Güdel Group realises solutions for motion tasks in the individual automation. Martin Sträb, CEO of Güdel Group, emphasises „we will be able to work out even better automation solutions for the transformer industry together with our partner GEORG. The efficiency will be increased further and thereby also the satisfaction of our customers. I look forward to our collaborative work“.

GEORG brings in profound knowledge of the entire line technique in the transformer industry – from the decoiling of the strip from the coil over the cutting-to-length of the strip to the cutting of the laminations and the stacking of the cores. Güdel contributes the robot handling systems and the networking of the individual components among each other.

As there are several GEORG customers who cut ahead and stock laminations which they want to stack to a core with an offline system at a later stage, the focus for the first common projects will be the development of an offline system for the automatic stacking of transformer cores.

The laminations cut by the GEORG line and interim stored are picked up and stacked fully automatically by the Güdel robots. For the positioning, the robots achieve highest accuracies and beyond that accelerate the core stacking process significantly. The direct data transfer from the cutting line to the robot unit makes time-consuming manual processes redundant. By this data coupling, the new systems can be easily integrated into digitally networked environments and thus prepare the ground for industry 4.0 / IoT.

Bernd Peter Schmidt, Managing Director of the transformer business division at GEORG sees considerable benefits for his customers: „By the cooperation of our two companies – who both have an outstanding reputation in their respective field – we will deliver complete systems that make the stacking of the laminations much more effective. We make use of the vast experience and well-proven standard components of Güdel. This means for our customers: innovative and at the same time reliable technology with considerable cost advantages.“

Rocco Montalenti, General Manager Business Unit Technologies at Güdel relies on the market knowledge of GEORG: „For more than 30 years, GEORG manufactures transformer lines and has an impressive market share worldwide. The GEORG employees know the conditions in the transformer industry inside out. By this, we are able to elaborate single-source solutions together that are exactly adapted to the requirements of our common customers.“

The cooperation is in accordance with the philosophy of both companies to offer optimal solutions for smooth transformer production processes.

New INGENERIC microlens arrays offer significant advantages in optical applications

Micro-optics for beam shaping, collimation, and homogenization: Highest precision molding of high refractive index glass

New INGENERIC microlens arrays offer significant advantages in optical applications

Single-sided microlens array with 400 lens elements and square aperture, two-dimensional

INGENERIC premiers their new microlens arrays with high refractive index glass at this year’s „Laser – World of Photonics“. Manufactured in a precision glass molding process, they are characterized by high dimensional accuracy. INGENERIC develops customized arrays and brings them to commercial serial production.

At the trade fair, the company based in Aachen, Germany is presenting its new microlens arrays with up to 500 individual lenses and dimensions of up to 60 x 60 mm, for example for beam shaping and light homogenization.

INGENERIC works with precision molding techniques, which ensure that high refractive index glass takes on precisely the form of the molding tool. The molds manufactured by the company to sub-micron precision enable the arrays to be produced with exceptionally high accuracy and reproducibility. INGENERIC successfully manufactures arrays with minimal transition zones, highest filling factors and minimal pitch errors, even in large batches.

When it comes to designing micro-optics for special applications, the process offers significant degrees of freedom: Compared to the etching process, optics can be far more complex with a larger radius-to-aperture aspect ratio. Furthermore, the process excels with a relative radius tolerance better than 0.2 %, which is fully reproducible in serial production.

Dr. Stefan Hambücker, a Managing Director at INGENERIC, sees clear advantages for his customers: „As one of the very few European manufacturers involved in the development and manufacture of the new microlens arrays with high-refraction glass, we are not only opening up new markets to our customers. We also help them to improve their existing systems. They can improve the quality of their products while at the same time they meet the cost requirements of serial production.“

INGENERIC manufactures microlens arrays with aspherical or spherical lenses that are planoconvex, biconvex or convex-concave, and which have a circular or rectangular aperture measuring from 0.2 to 3.0 mm. They can have dimensions of up to 60 60 mm.

Beam-shaping lens beamPROP

Along with its standard portfolio, INGENERIC is also exhibiting its new beam-shaping optic beamPROP 200 at the fair. It is a key component for fiber coupling the laser light from diode bars and for dense wavelength beam combining. INGENERIC has now reduced the pitch from 500 and 400 to 200 μm, which expands its geometry spectrum for use with additional laser bars.

The beamPROP from INGENERIC enables customers to achieve significantly better and more reproducible results than with components manufactured in other ways. INGENERIC can leverage the expertise from its tried-and-tested production technologies for the manufacture of the new beamPROP; a precise and automated assembly technology is applied here.

The advantages of INGENERIC beam-shaping optics over other manufacturing processes include:
-Optimal use of the aperture due to the smallest possible transition zones and particularly high filling factors
-Minimal aberration due to manufacturing accuracy
-Precise beam rotation thanks to the high accuracy of the lens center thickness of +/- 6μm
-Minimal pointing errors due to the precise alignment of the front and back of the lenses

INGENERIC at the „Laser – World of Photonics“ in Munich,
June 26 – 29, 2017:
Hall B1, Booth 430

Background: Precision in detail

The array structures typically have dimensions in the sub-millimeter range, and the dimensional accuracy is sub-micron at less than 250 nm. This makes it possible to produce arrays with high filling factors and to make the best possible use of the optically effective surface area: INGENERIC reliably implements transition zones of less than 10 μm. The benefit to the user: Optimal beam shaping and high-efficiency transmission and coupling.

High-precision molding keeps the offset between the upper and lower sides of the array under 5 μm. In addition, there is very high pitch accuracy: INGENERIC reproduces the separation between the individual lens center points with an accuracy of better than 2 μm over a length of 25 mm, so there is no accumulation of errors across the width of the array.

For some micro-optics – particularly the two-sided structures – the exact adherence to the central thickness is vitally important, since they have a telescopic effect and the slightest deviations lead to aberrations. INGENERIC achieves accuracies close to +/-6 μm here.

Compared to conventional methods like fused silica etching, INGENERIC achieves a relative radius tolerance better than 0.2 percent, which in serial production is precisely reproducible from wafer to wafer.


Founded in 2001 in the university-city of Aachen, Germany, INGENERIC GmbH develops and manufactures high-precision micro-optic components for high-power applications, along with optical and laser systems including fiber couplers, homogenizers and collimation modules for science, medicine, and measurement technology.

Today, INGENERIC is one of the few manufacturers in Europe to develop and manufacture glass micro-optics for beam shaping in semiconductor diode lasers according to the individual specifications of its international customers. The company handles the entire process chain from the lens design and the development of prototypes through to the small-batch production and serial manufacture.

INGENERIC also produces high-power laser systems. For the HiLASE project, for example, INGENERIC supplied a number of high-energy lasers delivering 10 pulses per second with an energy of 100 Joules and a power output of 1kW.

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


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.

Küttner Automation: Virtual commissioning in the „digital factory“ shortens the commissioning phase and speeds up the ramp-up

Plant modernization in the metal industry: Commissioning times for automation systems are cut by up to 75 percent.

Küttner Automation: Virtual commissioning in the "digital factory" shortens the commissioning phase and speeds up the ramp-up

When production is restarted, many processes and sequences have already been tested.

„Virtual commissioning“ provides the possibility of testing and verifying the perfect functioning of automation systems and optimizing controls and process steps before the „real“ commissioning takes place in the metal industry. Various successfully accomplished projects at the Gienanth iron foundry in Eisenberg, Germany, have demonstrated that commissioning times can be markedly reduced by simulating the equipment and functions beforehand – in a „digital factory“.

In modernization or rebuilding projects, every single day counts. Once a plant has been taken out of operation for a rebuilding measure, everything possible is done to bring it back on stream as fast and smoothly as possible. One is frequently presented with the situation that the time left for commissioning the electrical equipment is only very short due to unforeseeable delays occurring during the installation of the mechanical equipment. Against this backdrop, the success of a revamping project largely depends on how quickly and reliably the hardware and control software can be tested and optimized.

The „digital factory“

In numerous projects, Küttner Automation – the company within the Küttner group specialized in automation systems – has made it possible to reduce commissioning times and accelerate ramp-ups by applying the approach of „virtual commissioning“.

The process is based on the creation of a testing environment in which all mechanical, hydraulic, pneumatic and electrical components of the control systems are connected into a „digital factory“. This simulation scenario allows processes to be optimized and faults in the functional sequence to be identified and corrected beforehand, i.e. prior to the installation on site. The result: all automation sequences have been tested and approved before the new plant goes live.

The control equipment is commissioned in a virtual environment at a very early stage of the project – in parallel with the manufacture and assembly of the machinery. This means no testing and fine-tuning of the control software under time pressure as is very often the case when these activities take place during the „real“ commissioning. Therefore the commissioning activities on site can concentrate on the signal and field level. Moreover, the virtual approach often results in a shorter ramp-up phase, as there will be fewer failures and plant standstills.

Friedhelm Bösche, Head of Software Development at Küttner Automation in Trier, always offers virtual commissioning as an option for modernization projects. „Simulating the preliminary commissioning involves some effort in the beginning. But this pays off later on in the form of major time savings. We know from a great number of projects that the time needed to commission the real systems can be cut by up to 75 percent when the software has been pre-tested in a virtual commissioning scenario.“

A recent example

Küttner has recently revamped various facilities at the Gienanth foundry in Eisenberg, Germany, among others a sand preparation plant. For this project, Küttner Automation supplied the automation systems, including pre-testing in a virtual commissioning environment.

Roland Walter, Project Manager at Gienanth, summarizes the project: „We met all deadlines, although we only had two weeks“ time for the commissioning. The virtual commissioning had made us confident at a very early stage of the project that the processes would run as desired. Our production staff were given the opportunity to give their input and test the sequences beforehand. This has greatly contributed to a fast commissioning process.“

Gentle finishing of extremely thin work pieces with Turbotron centrifugal disk finishing machines

Deburring, edge radiusing, surface smoothing and polishing of mass-produced work pieces

Gentle finishing of extremely thin work pieces with Turbotron centrifugal disk finishing machines

Walther Trowal offers fully automatic systems with work piece loading and unloading

With the innovative option „gap rinsing“ the new Turbotron centrifugal disk finishing machines from Walther Trowal are ideal for finishing extremely thin fine-blanked parts. The new machines lower the investment expenditures and offer high uptimes.

Walther Trowal is the first supplier of mass finishing equipment who brings a new line of TT centrifugal disk finishing machines to the market with spinner and wear ring completely made from polyurethane and a rinsing system for the gap between spinner and stationary work bowl. This system prevents thin parts getting caught in the gap and get damaged. The new TT machines are a cost effective, highly wear resistant alternative to conventional mass finishing machines, especially for processing very thin work pieces.

To date the removal of burs and radiusing of edges on thin, relatively small parts required the use of centrifugal disk machines with special spinners made from ceramic or tungsten carbide steel. To prevent thin parts getting caught in the gap between the rotating spinner and stationary work bowl the precise setting of the gap was crucial for achieving the required finishing results.

Since even minor damage of the delicate spinner could result in high repair costs, the engineers at Walther Trowal were looking for a more economic solution.

The recently developed gap rinsing system now allows utilizing the spinners and wear rings Walther Trowal has been employing in large quantities in its standard centrifugal disk machines. This helps to drastically reduce the equipment expenditures, because PU is much less complicated to handle than, for example, ceramic materials. In addition, the gap size can be easily adjusted with the proven standard gap setting system. The pressure created by the rinsing system ensures that thin parts can no longer be drawn into the gap between spinner and wear ring.

Contrary to other mass finishing systems for deburring and grinding of thin components the new disk machines are operating with high water level in the work bowl. This helps prevent the work pieces from sticking to each other or clinging to the wall of the work bowl.

Christoph Cruse, general sales manager at Walther Trowal, sees significant benefits for his customers: “ Our new machines represent an economic, low-wear solution. Ceramic materials used to date are relatively brittle and can easily chip! This can cause costly damage to spinner and wear ring. Since we have worked with polyurethane for many years, we are very familiar with this material. To come to the heart of the matter: We have developed a smart, cost effective solution that works great for our customers.“

Walther Trowal offers the option „gap rinsing“ across the complete range of Turbotron disk finishing machines, from simple stand-alone units with manual work piece loading and unloading to large, fully automatic systems with hydraulic loader, external vibratory screening machine and media return conveyor.


Surface finishing with Turbotron centrifugal disk finishing machines

The high processing intensity, typical for the Walther Trowal centrifugal disk finishing machines, is achieved by the highly intensive interaction between processing media and work pieces and the high pressure of the media on the work piece surface created by the centrifugal force of the rotating spinner.

The spinner rotates with a speed of between 60 and 250 U/min. The centrifugal force created by this movement pushes the mix of work pieces, media and process water up the inner wall of the stationary work bowl. Once it has lost its kinetic energy the work piece/media mix collapses back to the spinner, from where it is accelerated again.

Facts about Walther Trowal

Since 1931 Walther Trowal develops, manufactures and markets modular and custom engineered solutions in the field of surface finishing.

Initially only making vibratory finishing equipment, over the years 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 parts, last but not least, the coating of mass produced small parts.

Walther Trowal offers not only various types of equipment but complete surface treatment systems: By linking the various equipment modules and automating the complete process, we are able to precisely adapt our process technologies to the technical requirements of our customers. This also includes various types of peripheral equipment and process water cleaning and recycling systems. Of course, we also offer comprehensive pre- and after-sale service like sample processing in one of our demonstration labs and global repair and maintenance service.

Walther Trowal serves many customers in many industries around the world. For example, in the automotive and aerospace industry, medical engineering and wind power generation.

Science Research Technology

Zink Körner cuts energy consumption in galvanizing by 15 percent

Efficient furnaces for hot dip galvanizing

Zink Körner cuts energy consumption in galvanizing by 15 percent

A galvanizing furnace for cable support systems

The new RECU-CHANNEL recuperative heat exchanger system may achieve energy savings of more than 15 percent in batch-parts, wire and small-parts galvanizing. In typical batch-parts galvanizing plants, this may result in approx. 30,000 euros saved on natural gas costs every year.

For galvanizing at temperatures between 450 and 460 °C, Zink Körner has developed its new RECU-TEC hot dip galvanizing technology, which allows the input energy to be recovered directly in the furnace. These furnaces are equipped with a steel tank and natural-gas fired flat flame burners.

Innovative recuperation technology

The new RECU-CHANNEL recuperative heat exchanger system heats the kettle very uniformly and exactly to the required temperatures. Operation of the furnace requires more than 15 percent less energy than traditional systems. Thus, more than 30,000 euros per year can be saved on natural gas costs, for example, in case of a batch galvanizing plant with an average through-put rate of 6 tons per hour.

While in conventional systems without RECU-CHANNEL technology the waste gas collects at the top, RECU-CHANNEL systems suck the waste gas from below in a controlled way allowing the waste gas to flow downwards past the outside surface of the kettle wall. Thus the waste gas transfers to the lower part of the tank exactly that amount of energy that is required for the process.

The channels are arranged at both long sides of the furnace extending along their complete length. Thus the waste gas travels long distances, giving it more time for the heat transfer. Using the residual heat in the RECU-CHANNEL to preheat the combustion air leads to a further increase in furnace efficiency.

The result: While the waste gas temperature of furnaces without RECU-TEC usually reaches 550 °C or more, the waste gas temperatures of the new furnaces are always below 400 °C, even in case of full load operation. This is a clear indication that the input energy is extremely efficiently used.

Highly efficient burner technology

Zink Körner has developed the modulated KÖRNER FL 15/80 flat flame burners specifically for the heating of steel kettles. These burners feed just as much energy to the galvanizing furnace as necessary at any point in time.

Unlike intermittent burners, they operate with a combustion air ratio of only 1.10 – hence with much less surplus air than usual. Their efficiency is 10 to 20 percent higher and gas consumption correspondingly lower than that achievable by burners operating with a ratio of, let“s say, 1.20.

Additionally, the modulating operation avoids short-term consumption peaks. This saves on gas procurement costs as the gas suppliers calculate their provision fees based on the peak load of the furnace.

Each of the diffuser plates of the new burners is supported by three rods fix mounted to the burner port. This arrangement achieves constant pressure conditions which allow the flame to be adjusted with utmost precision. For the user this provides the benefits of ideal combustion ratios and minimal gas consumption.

The burners are installed along the long sides of the furnace at two thirds of the furnace height (from the bottom). At that position, the heat requirement is highest due to the heat loss at the bath level.

About Zink Körner

Zink Körner GmbH designs and manufactures the complete array of hot-dip galvanizing equipment for single parts, tubes and pipes, miscellaneous small parts and centrifugal parts.

The supply range encompasses complete galvanizing plants, including pretreatment and handling equipment. The company provides design, engineering, manufacture, installation, commissioning and after-sales services. Zink Körner maintains a worldwide network of branches and licensees.

Zink Körner has launched many pioneering developments during its company history. For example, as early as at the beginning of the 1970s the company built the first automated centrifugal galvanizing plants, which have markedly improved the quality of the end products and the energy efficiency of the galvanizing process. The company took another innovative move by developing dedicated burner technology for hot-dip galvanizing applications.

Zink Körner is a company of the Körner Group, which was established in 1928. Thus the Group builds on more than 80 years of experience in industrial furnace technology and auxiliary equipment.

Within the Group, Wire Körner GmbH designs heat treatment equipment for wire and narrow strip. TVT Kordt GmbH develops plants for thermal process technology, with a focus on industrial furnaces for the heat treatment of steels, special steels and non-ferrous metals.
