Hydraulic Screen Changer Breaker Plate

The Breaker Plate in a Hydraulic Screen Changer is a robust, perforated metallic disc made from durable materials like high-grade alloy or stainless steel, positioned within the sliding plate to provide essential mechanical support for the fine wire screen pack filter media. Its primary function is multifaceted: it physically prevents the screen from rupturing under the high melt pressure (25-35 MPa), straightens the molten polymer's spiral flow from the extruder screw into a laminar, axial stream to improve melt homogeneity, and helps build the necessary back pressure for optimal material mixing and consistent extrusion, directly impacting final product quality.
