Abstract

1,199,649. Compression moulding of powder. ALLMANNA SVENSKA ELEKTRISKA A.B. 27 Dec., 1967 [27 Dec., 1966], No. 58650/67. Heading B5A. A device for producing a pressed powder article, e.g. a tubular article, includes a piston 6 slidable within a cylinder 12 and supplied with a charge of powder which fills an annular space 11 between a core 3 and a flexible tube 7 adjacent a perforated wall of the piston surrounded by an annular space 9 in which a pressure medium such as oil or water is located. The powder is initially compressed between an annular punch 4 and a punch 1; on continued downward movement of the punch 1 the assembly 3-7 is forced downwards into the cylinder so that the pressure medium in the space 9 is forced against the tube 7 to compress the powder radially. The upper punch is then moved away allowing the assembly to return to its upper position whereupon the lower punch moves upwards to expel the tubular product. The initial axial compression is not essential.
