ABSTRACT:
A press for cold-forming granular tungsten carbide cutting tool edge blanks for sintering, it has helical edges on jaws which open and close around a center pin and are of a depth which allows for shrinkage during sintering, top, bottom and side members seal the forming cavity; a graphite sinter fixture has similarly-shaped forming and sealing components to the press but relies only on gravitational surface reaction to close components against a pressed blank to prevent shrinkage distortion during sintering.
