摘要：A method of injection moulding an article, the method comprising the steps of:(a) providing an injection mould comprising a plurality of mould parts defining a mouldcavity of the injection mould, the plurality of mould parts including first and secondmovable mould parts, the injection mould further comprising an injection inlet for
injecting molten thermoplastic resin material into the mould cavity, wherein the injectioninlet is located in the vicinity of the first movable mould part and the second movablemould part is remote from the injection inlet; (b) disposing the first and second movablemould parts in a first configuration so as to define a first intermediate moulding cavity, inwhich first configuration the first movable mould part is in a first rearward position andthe second movable mould part is in a first forward position; (c) injecting moltenthermoplastic resin material into the first intermediate moulding cavity through theinjection inlet to fill the first intermediate moulding cavity with the molten material; (d)closing the injection inlet; (e) after commencement of the injecting step and at leastpartly after the closing step, moving the second movable mould part from the firstforward position to a second rearward position; (f) moving the first movable mould partfrom the first rearward position to a second forward position; and (g) moving the secondmovable mould part from the second rearward position to a third forward positionthereby to dispose the first and second movable mould parts in a final configuration soas to define a final moulding cavity of the injection mould filled with the molten material,the final moulding cavity defining a cavity outer surface which defines the outer shape ofthe article to be moulded.
