Plastic Extrusion Screen Changer

The Plastic Extrusion Screen Changer is a critical component in the extrusion process, designed to filter out contaminants and impurities from molten polymer before it reaches the die head. Its main function is to ensure a continuous flow of clean material, which is vital for maintaining high product quality and protecting downstream equipment. Available in types like manual, hydraulic, and fully automatic continuous models (such as dual-piston or belt changers), the device allows for quick and efficient screen pack replacement. Key benefits include increased production uptime, reduced scrap material, minimized pressure fluctuations, and low maintenance, ultimately enhancing overall line efficiency for materials like PE, PP, and PET.
