Abstract

Improved die and punch In the manufacture of SiN powder, compacts, the use of a floating mandrel made from SiN improves the thermal insulation properties of the equipment. reduction in main punch size may also be effected. The floating mandrel is positioned between the means of applying the pressure from the machine and the head of the punch. The mating surface of the tubular die, the bottom plug, the flat working surface and the floating mandrel may be coated with a further refractory powder.
