Title: Friedrich Hanstein: Innovator in Plastic Forming Technologies
Introduction
Friedrich Hanstein is a notable inventor based in Gross-Zimmern, Germany. He has made significant contributions to the field of plastic forming technologies, holding a total of 10 patents. His innovative methods have advanced the production processes of plastic components, particularly in maintaining surface quality during forming operations.
Latest Patents
One of Hanstein's latest patents is a method for forming reducing formation of impressions from the forming tool. This method ensures that the surface qualities, especially the gloss of plastic sheets, plates, strips, or tubes, remain undamaged during the molding process. The tool is maintained at a temperature in the thermoelastic state region of the plastic until disengagement, while the formed plastic is cooled at its rear side to below the softening temperature. This allows for a smooth disengagement from the forming tool while it is still hot.
Another significant patent is the process for the production of a cupola-shaped plastic piece with a flat rim. This innovative process allows for the creation of cupola-shaped plastic pieces without the need for trimming the rim. By using radiant heat to selectively heat the plastic sheet, the rim remains tension-free until the forming process begins. This method enhances the efficiency and quality of plastic production.
