Isothermal forging presses

Our isothermal forging presses produce sophisticated, heavy-duty components for high-tech products.  We furnish our customers with first-class solutions including control systems for the fine-tuning of pressing speeds. Our presses are designed for high-precision applications indispensable in the aircraft/aerospace and medical engineering industries. The challenge here is to manage pressing speeds of 0.01 mm/s in controlled operation, which is ensured by our own electrical and hydraulic control engineering.

Siempelkamp also offers plants to be used for isothermal forging. They comprise the furnace, the feed manipulator, the forging press, the die heater, the hydraulic drive system and the entire automation technology. The plant control for isothermal forging presses monitors and documents the process parameters in compliance with the certification standards to be observed in the aircraft industry.
