Polymer Screen Changer

The Polymer Screen Changer is a vital filtration device in polymer extrusion processes, designed to remove impurities and contaminants from molten plastic, rubber, or ceramic materials. Available in manual, hydraulic slide plate, continuous dual-piston, or self-cleaning automatic rotary types, its primary function is to ensure a consistent flow of clean material, protecting downstream equipment like melt pumps and dies, and enhancing final product quality. Continuous models allow for filter screen replacement without stopping the production line, minimizing downtime and scrap, which is crucial for high-volume or sensitive applications across industries like film, sheet, pipe, and recycling.
