Abstract

Plastic articles with separately moving components are made by injection moulding one component first, and injection moulding a second component at a lower temp. and in a thermoplastic which will not bond to the first, so that the first component is not distorted in any way. The process uses on composite mould tool only, and moulds the second component without moving the first.
