Innovative induction heating of extruders for plastics

On account of the focus on the energy consumption of the industry as a result of the energy transition, especially energy consuming processes are being placed under the microscope in relation to their energy efficiency. Extrusion machines used to produce plastic products are thus also being investigated. The heating of the extrusion tubes of the plastic extruders is mainly achieved in the conventional method of resistance heating with heating tape. With the goal of process optimization and at the same time improving the energy efficiency of the extrusion machines, an induction heating system was developed which allows manufacturers and operators of the machines to easily change over to the new energy efficient operation.
