Review of manufacturers, licenses, required investment in equipment, and cost benefits expected in return.
This is in addition to evaluation of hardware, processing parameters, problems, and results of the application of these processes. The examples of some other processes involved include: photoimaging, in-mold circuit definition, two-shot, one-shot, two-cavity shuttle design, valve gate technology, low-pressure injection molding, in-mold decoration, plating, in-mold assembly, sandwich molding, and large part molding.

Professor Dr.-Ing. Helmut Potente gained his doctorate at the IKV Institute of Plastics Processing at Aachen University of Technology. From 1971 to 1974 he was head of the Plastics Process Engineering Laboratory at Westfälische Metallindustrie KG Hueck & Co. in Lippstadt/Germany. In 1974 he was appointed an academic officer and Professor of Joining, Forming and Refining Technology for Plastics at Aachen University of Technology. Since 1980 he has held the Chair of Plastics Engineering at the University of Paderborn and been Head of the Institute of Plastics Processing.
