Abstract

1374073 Isostatic moulding of powder SINTERMETALLWERK KREBSOGE GmbH 19 July 1973 [25 July 1972] 34488/73 Heading B5A [Also in Division C7] In a method of making a sintered component having an internally screw-threaded portion, a sintering powder is initially compacted by vibration in a mould having an externally screwthreaded core and the compacted powder is isostatically compressed in the mould and then sintered. A suitable mould comprises an elastic tubular casing 1, an externally screw-threaded core 2 providing a space 5 for the powder and covers 8 releasably and rigidly connected to each other by screws 6. In a modification, the core is mounted on only one of the covers and extends only partly along the length of the casing; the covers are connected to each other by studs. The assembled mould is subjected to isostatic pressure in a press. After sintering, the component may again be isostatically compressed, using a calibrated mandrel instead of a core.
