PROCESS FOR MANUFACTURING HOLLOW PLASTIC OBJECTS

摘要

A process is disclosed for manufacturing hollow plastic objects. Cores are produced in casting moulds, the cores are placed into moulds of moulding presses and are enveloped with plastics (35) which then solidify. The moulds are then heated up to a temperature at which the cores melt and are withdrawn from the moulds. The cores are made of shell halves (32, 33) which are assembled before being extrusion-coated with plastics (35).
