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

• Improved process reliability
• Accurate temperature uniformity
• High efficiency

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.

The new Indian representative Mehul visited extrutec's headquarters at Lake Constance this week. Mehul and his company Stevag have been representing extrutec on the Indian market since October this year. The aim of the cooperation is to provide extrutec's new and existing customers with more personal on-site support to ensure a long-term partnership.

Changbao Steel is well known for its seamless extruded stainless steel pipes. The company invested in a completely new extrusion line for the production of these tubes.

After 8 months of intensive cooperation between extrutec and Changbao, the production acceptance took place at the extrutec group subsidiary TCT Induktionstechnik in Menden. A total of 32 customised induction furnaces were manufactured for the process-accurate heating of high-alloy stainless steels for various material dimensions with an installed system output of approx. 9 MW. In addition to the induction furnaces, this complex project also included various auxiliary equipment, switchgear and other system components. The equipment will be commissioned by extrutec in early 2025.

Frequent visits to our customers are an important part of the day-to-day business of the extrutec aftersales department. Personal discussions provide valuable feedback that helps us to further improve our aftersales service and the overall performance of our equipment. A visit to our Turkish customers took place as planned. One of the companies visited was Asen metal, where an extrutec heating system is in operation together with a profile cooling system. The aftersales department provides lifetime support for existing extrutec equipment and also advises our customers on frequent upgrade projects.

Last week, extrutec was featured on Korean television. The KBS (Korean Broadcasting System) broadcast a report on aluminum extruder Almac. The focus was on the new 14" automotive line. This line meets the specific requirements of domestic car manufacturers. extrutec supplies the critical components of the automotive extrusion line, consisting of an in-line gas induction furnace with hot saw and upstream ESU (Energy Saving Unit), as well as a high-performance profile cooling system.

Industry 4.0, sustainable energy supply and electrification are the topics that will shape our future. In keeping with our motto ‘Green the new heat for extrusion’, we are happy to be participating for the first time in the Electrical Engineering Day of the HTWG Konstanz University of Applied Sciences - Technology, Business and Design Talent Fair in order to attract motivated and talented electrical engineers to our company.

The worldwide first electrically resistance-heated highspeed-convection oven (EHKO) in inline design for the continuous heating of aluminum logs is ready for delivery. The newly developed furnace type has been put into operation and intensively tested at extrutec's site in Menden over the last few weeks. The system configuration consists of an EHKO for base heating, an induction furnace arranged directly in line for tapering the billet and a downstream hot log saw. The induction furnace is manufactured in-house by extrutec subsidiary TCT Induktionstechnik. The tests carried out on the system once again confirm the calculated and simulated values such as heat transfer and the extremely high efficiency of 87%. The system will be put into operation in Finland in the next few weeks.

Three exciting days at the Aluminium trade fair have come to an end. The extrutec team would like to thank you for the consistently well-attended stand and the many great personal discussions.
See you again in Düsseldorf in 2026!

Today's official ground-breaking ceremony marks the start of construction work for the site expansion at extrutec's main office in Moos. A second office building will be constructed within the next 12 months. The new building is a response to the positive business development resulting from the expansion of the product range and the company's global orientation. The new building will be specially designed to meet the needs of extrutec's technology and development department. As with the extrutec machines, attention will be paid to minimising energy consumption, which will be ensured by geothermal heating and a photovoltaic system, among other things. Completion is planned for November 2025.
