It was a pleasure to engage with numerous motivated, talented engineers and present our company. We are looking forward to the upcoming applications and are excited for further discussions with future professionals who will work with us on sustainable and innovative solutions.
Yesterday was a special day for the extrutec site at Lake Constance. The construction of the second building is in full swing. The preliminary building work was ceremoniously completed yesterday.
At both extrutec sites in Moos and Menden, expansion projects are currently underway to increase the capacity of office and production workplaces. Both locations have reached their capacity limits and are now being progressively adapted to the requirements of extrutec's strategic orientation. This includes increased service activities in all areas and a focus on heating projects for all metals.
The article highlights the installation of a state-of-the-art induction heating furnace from extrutec GmbH at GEI's extrusion plant in Youngstown, Ohio. The project aimed to enhance process reliability, improve temperature uniformity, and increase energy efficiency.
The new furnace, equipped with advanced IGBT converter technology, enables precise temperature control, reduces scrap, and optimizes production efficiency.
This collaboration underscores extrutec’s commitment to delivering cutting-edge solutions for the aluminum extrusion industry.

Michael Werner from our Cedar Springs Michigan-office has attended another great Aluminum Extruders Council (AEC) conference in San Antonio last week. As always, the conference offered a very educational and exciting program. A particular highlight was the "Market Update & Outlook" presented by Karen McBeth (S&P Global Insights), aside of catching up with longtime industry friends.
In extrutec's machine business, designs often have to be adapted to the specific spatial conditions on site, and typically a manual side measurement is carried out at the beginning of the project. Certain key points are measured and then transferred to the CAD models for the system design. In the future, extrutec will use a 3D scanner for difficult spatial conditions. The laser measurement process generates a point cloud that is then assembled into a virtual environment on the computer. Real images are also taken to help the project team orientate themselves. The systems designed by extrutec can then be inserted into the real environment in advance and adjusted to the exact dimensions. In this way, space problems and interfering edges can be identified at an early stage and the installation time can be further reduced.
Three successful days at Metef have come to an end. Although visitor numbers were lower than expected, we were still able to engage in valuable discussions and establish new connections.
The focus was on our resource-efficient and environmentally friendly solutions in the areas of heating and cooling, contributing to a significant reduction in energy consumption and carbon footprint.
We take away many interesting insights and look forward to future opportunities to present our innovative solutions and provide expert support to our customers.
The maintenance of induction coils in our workshop in Menden executed by our subsidiary TCT, which specialises in coil production and maintenance, is an essential part of ensuring continuous production and high availability of your induction coil. In order to avoid production downtimes and extend the service life of the induction coil, professional maintenance of the coil is essential. That is why we offer all customers customised maintenance and repair of their coils (including those from other manufacturers). Get in touch with us!
extrutec is pleased to announce the successful completion of a furnace replacement project at General Extrusions International, Inc. (GEI) in Youngstown, OH. In August 2024, extrutec was awarded the contract to replace the existing 7" induction furnace on the 1675 ton press line. The main objectives for the furnace replacement were
To achieve these objectives, the new furnace is equipped with 5 individual heating zones for precise billet taper. The power to the multilayer coils is controlled by the latest IGBT converter technology with 5 individual outputs. The IGBT converter is equipped with an unregulated diode rectifier to achieve a constant power factor of 0.95 or better, without capacitors or filter reactors. The IGBT converter allows continuous adjustment of the power density in the coils, which in combination with the thermocouples in each coil section, provides high temperature accuracy.
Despite the challenging short timeframe, extrutec was able to deliver the equipment as promised for an installation during the Christmas shutdown. We'd like to thank the whole team at GEI for their excellent cooperation.
The first hot billet was heated at Mäkelä in Finland. The newly developed inline EHKO (electrically resistance heated high convection oven) plays a key role in Mäkelä's decarbonization plans. The concept combines two electric heating methods. The decisive factor is the extremely high overall efficiency of the system, which is achieved by base heating with heating elements and final taper heating with induction. As the new equipment will be replacing an old gas heater, Mäkelä will save 960 tons of CO2 per year.
