Abstract (en)

[origin: WO9910158A1] The invention relates to a method wherein a first plastified material is injected into the cavity of an injection mould whereafter another plastified material is also injected into said cavity. The inventive method is characterised in that the first plastified material is fed into the cavity in such a way that it wets only one partial area of the cavity wall and the other plastified material is subsequently fed into the cavity so that it wets at least one part of the remaining area of the cavity wall. Said method enables injected moulded parts to be manufactured using various materials and by means of simple injection devices.
