Parallel Twin Screw Barrel for PVC Extrusion

Parallel twin screw extruder is a type of extrusion machinery used in the plastic processing industry. It is designed to melt and mix plastic materials, and then force them through a die to create a specific shape or profile. The twin screw extruder has two screws that rotate in parallel, with intermeshing teeth that interlock and move the plastic material forward.  The screws are typically made of high-strength steel and can be heated or cooled to control the temperature of the plastic. The extruder is usually equipped with a variety of sensors and controls to monitor and adjust the process parameters, such as temperature, pressure, and speed. The parallel twin screw extruder is widely used in the production of plastic pipes, profiles, sheets, films, and other products.
