Title: Hellmut Boden: Innovator in Plastic Processing Technology
Introduction
Hellmut Boden is a notable inventor based in Illingen, Germany. He has made significant contributions to the field of plastic processing, holding a total of 4 patents. His work focuses on improving the efficiency and effectiveness of plastic material treatment.
Latest Patents
One of his latest patents is titled "Process and apparatus for two stage treatment of plastic materials." This invention addresses the challenges faced in the preparation and production of plastic materials using a continuously operating double shaft screw-type extruder. The design features a primary stage that is pressure-tight and mounted on the extruder's housing. This primary stage consists of a vertical double conical container with screw-type helices that are driven from above. The helices connect to replaceable feed elements, ensuring efficient delivery of material without intermediate dead spaces.
Another significant patent is for an "Apparatus for mixing and processing plastic material." This apparatus includes a separately drivable gear pump as a delivery unit. To prevent material deposits between the mixing apparatus and the delivery pump, the gear pump is directly mounted at the outlet end of the mixing apparatus. This design allows for direct feeding of the plastic melt into the gear pump's suction space, eliminating the need for cleaning operations after shutdown or material changes.
