Injection moulding, i.e. forcing the required volume of moulding material through a nozzle into a closed mould; Apparatus therefor incorporating preformed parts or layers, e.g. injection moulding around inserts or for coating articles {the inserts being deformed or preformed, e.g. by the injection pressure the inserts being positioned around an edge of the injected part}
