Direct Forming (DF)

Direct formed parts (DF)

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

Fields of application:

Die pressed mouldings 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.
