Abstract:
The present invention is a process for producing molded parts from a polymeric powder or metallic powder, wherein the molded part has a separation or a void. The separation or void is formed by inserting a separator or void-forming material into the die cavity before, during or after filling the die cavity with the powdered molding material that is to form the pressed part. After the pressed part is formed the separator or void-forming material is removed to provide the separation or void.
