Abstract

Machine has a cylinder with a supply orifice for the granular product to be moulded at one end, an injection screw to force the molten product under pressure into the mould through an injection orifice, and heating device for the cylinder. A fluted mandrel is interposed between the injection orifice and the screw. Mouldings with a mottled effect can be produced.
