COURSE PURPOSE: The Course in Plastics Processing Technologies provides students with the basic knowledge to navigate the plastics processing processes. Specifically, the course allows the acquisition of knowledge on the processing technologies of polymeric and composite materials, materials that occupy an increasingly significant weight in modern manufacturing processes. It is, therefore, a complementary course to Mechanical Technology which, on the other hand, teaches only about the conventional transformation processes of metals. The Plastic Materials Processing Technologies Course therefore includes elements relating to the extrusion and molding processes of the main plastic materials, as well as the forming processes of composite materials.
