Abstract

1,242,260. Moulding powder. BIRMING- HAM SMALL ARMS CO. Ltd. 2 Jan., 1970 [13 Dec., 1968], No. 59301/68. Heading B5A. The die 1 associated with punches 3 and 5 of powder compaction apparatus is first filled with powder and, before its compaction, the die is raised to provide a cavity 4 so that the pocket of air trapped within the cavity when the punch 3 reaches the position shown, cannot disturb the powder surface. The die may include an axially extending core rod and two coaxial relatively movable lower punches.
