Plastics: Plastics: Twin Screw Extrusion: Plastic Materials

Twin Screw Extrusion: Plastic Materials is the second training program of the eight course Twin Screw Extrusion series, designed to provide training for anyone working in a production environment. The training introduces the plastics industry and the nature of plastics materials, explains complex concepts such as melt viscosity and polymer flow, provides detailed explanations of both shear and shear heating with plastics, covers the behavior of both amorphous and crystalline polymers, and gives an understanding of shrinkage, orientation, and degradation.

The programs use 3D animation and actual production footage to emonstrate complex concepts. Important safety precautions are stressed throughout these training programs.Tailored for Twin Screw Extruders, these training courses provide specific information for all extruders from blown film to profile extrusion. Whether you use a co-rotating or counter rotating extruder, the information will relate to the equipment, materials, and processes operating at your facility.

This training series with help teach any employee the concepts relating to the machine, material, process, quality, startup, shutdown, problem solving, material handling as well as the correct terminology associated with Twin Screw Extrusion.
