Abstract

1,019,557. Injection moulding. CONTINENTAL GUMMI-WERKE A.G. May 24, 1962 [May 31, 1961], No. 19935/62. Heading B5A. A process for injection moulding rubber compounds comprises heating the rubber compound in an injection cylinder 15 to just below vulcanizing temperature and then injecting the compound through a nozzle 4 into a heated mould 9 so that it vulcanizes therein. The volume of the injection cylinder 15 is substantially greater than the volume of the mould 9, so that on reciprocation of the injection piston 5 only a small portion of the contents of the cylinder 15 is injected into the mould. The injection cylinder 15 is then refilled through a channel 14 by a screw conveyer 6. The material thus remains in the injection cylinder for a few working cycles before it reaches the nozzle 4, and during this period is gradually heated to just below vulcanizing temperature.
