In the plastic extrusion industry, Extruder screen packs are indispensable for ensuring product quality and operational efficiency. These layered metal filters, installed before the die, perform the essential function of purifying the polymer melt by removing contaminants such as carbonized particles, gels, and foreign materials. This filtration process directly translates to superior product quality with consistent dimensions and flawless surface finish.
Beyond contamination control, screen packs generate crucial backpressure that enhances melt homogeneity and mixing efficiency. They also serve as a protective barrier, safeguarding expensive downstream components like extrusion dies from abrasive damage. For manufacturers utilizing automatic screen changers, robust and well-designed screen packs are vital for achieving seamless, leak-free changeovers that maximize production uptime.
Our specialized screen packs are engineered for optimal performance. Manufactured from high-grade stainless steels (304, 316, 316L), they deliver exceptional durability under high temperatures and pressures. We offer comprehensive solutions from coarse to ultra-fine filtration, with full customization available for specific shapes, sizes, and specialized coatings to meet unique processing requirements.
