Abstract

606,331. Injection-moulding apparatus. BRITISH RESIN PRODUCTS, Ltd., and DAVIES, D. N. Feb. 8, 1945, No. 30544/47. Divided out of 606,259. [Class 87 (ii)] Liquid resin contained in a cup a enters a cylinder c through holes d in the latter, and is forced by a plunger e past a spring- pressed ball valve j through a nozzle f into a mould k<1>. The nozzle is cooled by water circulating in a channel g therein. Small ports m in the cylinder relieve suction on ascent of the plunger. The plunger is reciprocated by a lever or a crank. The mould is heated. Specification 583,236, [Group IV], is referred to.
