Abstract:
1. A process for making a moulded article consisting partly of a hard first plastics material, comprising: providing a first injection mould having a cavity which defines at least part of the shape of the article to be formed and having a cavity surface bounding the cavity; introducing a component which comprises a thin shell, made of thin sheet-form metal, plastic or a metal-plastic laminate or composite, a surface of which forms at least part of the outer surface of the article into the cavity adjacent to the cavity surface; injecting a first fluid plastics material into the first mould cavity, under conditions such that the plastics material flows into contact with the component and when the plastics material solidifies the hardened plastic material is fixed to the component and the component forms at least part of the outer surface of the article; then further processing the article in a second moulding operation by providing a second injection mould part having a second mould cavity therein; introducing the article into the second mould cavity of the second injection mould part; injecting a melted fluid second material into the second mould cavity and into contact with the article; and allowing the melted fluid second material to solidify sufficiently and such that when the second material solidifies the hardened second material is fixed to the article.
