Abstract

1,266,014. Moulding powder. TRW Inc. 24 Feb., 1969,'No. 48603/71. Divided out of 1,266,013. Heading B5A. A powder, which may be of metal, is isostatically compacted within a die 10 by placing it within a container 30 of relatively soft elastomeric material enclosed within a container of relatively hard elastomeric material, and compressing the assembly between punches 24, 26. The compact may then be sintered. Such compacts are stated to have a uniform porosity. In Fig. 4 a slab 52 of hard elastomeric material is located between a punch 26 and a container 30 of soft elastomeric material; alternatively the slab may be of soft elastomeric material with a rim of hard elastomeric material forming a seal with the die wall. Apparatus for fabricating tantalum anodes for capacitors is described.
