Abstract

In the injection moulding of hollow products, product material which forms the finished article is injection moulded around a removeable core corresponding to the hollow. One single injection moulding tool is configured for alternate moulding of core material and product material in one or more successive steps, each step including two part-stages. In one part-stage, core material is injected into the tool to produce a core, or a layer of core material is formed externally on a composite unit of core material and product material. In the second part-stage, product material is injection moulded to produce an article element or a layer of material externally on a composite unit. A tool for carrying out the method includes a body having tool-parts for moulding a core or an article element having anchoring parts for holding the core or element during movement to successive tool cavities of progressively larger volume. The tool is provided with ejector means for ejecting the composite unit from the tool.
