Direct Forming Polyimides

Polyimide Direct Formed Parts

With direct forming precise direct formed components are manu­fac­tured from high tem­per­a­ture plastics. High-speed automatic presses (mechanical or hydraulic) compact the powder in the mould cavity. The parts are then sintered for some hours at high tem­per­a­tures with the exclu­sion of oxygen.  

Benefits

Outstanding properties 

Direct formed parts made of TECASINT are particularly suitable for applications involving a high level of thermal and mechanical stress in which very good emergency running characteristics are required depending on speed and force.

Due to the high purity and the very good thermal stability of - 270°C to + 300°C, applications can also be implemented in a vacuum and in the cryogenic and high-temperature ranges.

Economic effiency

The direct forming technology in­volves practically no material waste. In most cases, reworking is also not required.

Due to the short cycle time, die pressing is also partic­u­lar­ly economical for precise volume parts from batch sizes of 1,000.
