Abstract
1428789 Injection moulding E LANGECKER 26 Sept 1973 [27 Sept 1972] 45052/73 Heading B5A In a method of injection moulding a body comprising a filling layer 27 of a thermoplastic material surrounded by a surface layer 25, 26 of another thermoplastic material, the material forming the filling layer is injected in the form of a tubular flow located between an outer tubular flow and an inner flow of surface layer material. The filling layer material is supplied from a plasticizer 23 and the surface layer material from plasticizers 22, 24. The supply of filling material is cut off by axial movement of a tube 9 to the position seen in Fig. 3 (not shown) before completion of the injection operation. The result is that a plug surface of layer material remains in the nozzle 12 which plug is introduced into the mould at the beginning of the next injection operation. The material of the centrally injected surface layer may be of different colour or composition from that of the outer tubular flow. Further, different materials may be used for the central and circular injections of surface material whereby the moulded body may have a surface layer of a different composition or colouring to that on the other side.
