One Tool Equals Three Processes

A German molder in the Bodensee district is showing off an interesting new co-molding approach that combines hard and soft plastic parts. The process is described in an interesting article by Matt Defosse, editorial director of Modern Plastics Worldwide. Muffler-Plastic of Pfullendorf, Germany, is mating rigid plastics such as polypropylene with a soft material using either an additional injection unit for expandable thermoplastic elastomer or a PUR mixing head. The twist is that the mold, developed by Georg Kaufmann Formenbau, has a second cavity for preforming of film or fabric. Defosse saw a demonstration of the tool making automotive compartment trim.
