Smart starch cap

This is a completely hardened 2 imp tool, incorporating slides for the embossed engraving. The parts are moulded from high density polypropylene were the colour has been matched perfectly. The cap incorporates a special sealing rib which can stop any leakage from the bottle with out the need for using a separate seal. The Mould tool uses a completely automatic unscrewing system. As the tool opens in the moulding cycle the internal cores automatically turn due to a fixed helix spindle and gears. Once the mould tool is completely open and the internal cores are clear of the moulding the part is ejected by means of two air valves.
