Abstract

1412864 Hot pressing apparatus ANNAWERK GmbH 6 March 1973 [9 March 1972] 10707/73 Heading B5A [Also in Division C7] Powders such as metals, non-metals and oxides are hot pressed in an elongated die with pressure applied at the ends, the die and heating zone being moved relatively to each other in the direction of the longitudinal axis of the die and the heating zone extending over only part of the die length. As shown in the Figure the powder 1 charged in die 2 is pressed by plungers 4 and heated by resistance or induction heater 5a which produces a heat zone shorter than the mould. The pressure on plungers 4 is applied via motor M, pump HD and valves SV and 7. The punches and die are moved relative to the heater 5a by a low pressure system comprising motor M, low pressure pump ND and valves NSV and the speed is controlled by regulator 8 and valve GSV. The die may also be arranged horizontally. Instead of hot pressing a single body, several shorter compacts separated by graphite discs 11 may be assembled in the die and hot pressed.
