DME (Madison Heights, Michigan / USA; www.dme.net) has introduced the “Quick Strip” mould making part ejection tool that is claimed to significantly reduce mould construction time and costs. The system eliminates the need for ejector plates and pins, risers and clamping plates, resulting in lower part costs, machining and maintenance. It also eradicates ejector pin holes, allowing cooling systems to be optimised, leading to faster cycle times.

The tool “lifts” the part from the mould cavity rather than pushing it like an ejector pin, leaving no marks on the part. For this reason, it was used by mould maker Deva (Lemgo / Germany) and OEM Hans Kroner Formenbau (Schloss Holte-Stukenbrock / Germany) on a project making parts for the Airbus A380.

Dirk Schmeling, general manager at Deva Kunststoff-Technik, said: “We were moulding parts for the Airbus and because of aesthetic requirements, ejector pin marks can’t be visible. We achieved higher surface quality using the 'Quick Strip' and reduced the mould construction time and costs considerably in the process.”
