Friedrichshafen, Germany — Two partners in the NILS intelligent lightweight structures network had a live demonstration at Fakuma of a complete production system making an insulated bottle holder in particle foam with a living integrated hinge, two integrated injection molded polypropylene screw-threaded fixing inserts and an integrated exterior decor.
Although Hiddenhausen, Germany-based molder and mold maker Krallmann Holding und Verwaltungs GmbH normally exhibits at Fakuma fairs in Friedrichshafen with a conventional booth, it teamed up this year on a joint booth with its well-established expanded polypropylene particle foam producer partner, Ruch Novaplast GmbH + Co. KG of Oberkirch, Germany.
The partners are showing a further development of the PCIM particle foam composite injection molding process that started originally with model aircraft wheels shown at Fakuma 2012.
The process begins with an articulated arm robot from Kuka Roboter GmbH, which picks up doughnut shaped EPP rings and inserts them into a single-cavity injection mold weighing 390 kilograms, designed and produced by Krallmann, mounted on a 1,000 tonne clamping force 470S 1000-170 injection molding machine from Arburg GmbH + Co. KG of Lossburg, Germany. FPT Robotik GmbH & Co. KG in Amtzell, Germany developed the robot and gripper system for the production cell.
