This is Kaupert
Dr. Ing. Kaupert GmbH & Co. KG has been specialised since 1948 in moulding and packaging chocolate as well as in deep-drawn plastic packaging. At the Erndtebrück plant, polycarbonate chocolate moulds are produced by injection moulding – from bar, praline and hollow-figure moulds to double moulds whose injection moulding process is simulated in advance using special software. At the Marburg plant, blisters, sorting inserts and workpiece carriers are produced on deep-drawing machines from thermoformable plastics such as PP, PET, PS, PC, PVC, PLA and bio-based films; film extrusion of mono films, which are 100 % recyclable, also takes place there. The value chain includes CAD-supported model development, toolmaking, production and in-house developed destacking machines (HES II, HES III, HES III-M). Customers include the food industry (chocolate, biscuits), medical technology, the pharmaceutical industry as well as the packaging and transport sector.
