Hydraulic Screen Changer Hydraulic Cylinder

The Hydraulic Cylinder for a Hydraulic Screen Changer is a precision-engineered, double-acting piston cylinder that provides the high, controlled force necessary to swiftly and seamlessly slide the filter plate (breaker plate) and screen packs in and out of the molten polymer melt stream without interrupting the extrusion process. Typically operating at pressures up to 200 bar, this critical component features robust construction, often from mild or alloy steel, with a specific bore diameter and stroke length matched to the screen changer size, ensuring fast, leak-free screen changeovers-often in five seconds or less-which is crucial for maintaining continuous production and product quality.
