Extruder, extruder is divided into metal and plastic extrusion machine (also known as plastic extruder, extruder, plastic extrusion machines), two different types of applications in different industrial fields.
In the processing of plastics and synthetic fibres, screw extrusion machines have a very wide range of applications. Screw extrusion machines belong to the constant torque loads, so ask for low frequency high torque. Introduced after the three crystalline S350 vector converter screw extrusion machines access to performance improvement. Inverter closed-loop vector control at low speeds would be at nominal torque output, and can accurately control the speed.
