Process for manufacturing hollow plastic objects

摘要

A process for manufacturing hollow synthetic resin bodies or objects in which cores are produced in casting molds, then placed into molds of injection molding machines, and subsequently enveloped with injected synthetic resin material (35) which then solidifies. The molds are then heated up to a temperature at which the cores melt and at which the molten cores can be removed from the molds. The cores are made of shell halves (32, 33) which are assembled before the synthetic resin material (35) is injection molded around them.
