Hydraulic Continuous Screen Changer for Sioplas XLPE Wire and Cable Extrusion Lines
The Sioplas XLPE extrusion process is the mainstream manufacturing technology for high-performance cross-linked polyethylene wire and cable insulation. Strict melt purity, stable pressure output and continuous production are essential to guarantee XLPE cable’s insulation performance, mechanical strength and service stability. As a core auxiliary device, the hydraulic continuous screen changer has become an indispensable configuration for standardized Sioplas XLPE cable extrusion production lines.
Different from conventional discontinuous screen changers, this hydraulic non-stop screen changer features a dual-channel sliding structure. It enables full-automatic screen replacement without shutting down the extrusion line. While one filter channel undertakes melt filtration, the other completes screen replacement and pressure stabilization, realizing zero interruption of polymer melt supply. This design thoroughly solves the problems of material waste, unstable melt pressure and defective products caused by frequent shutdown screen changes in traditional equipment.
Tailored for Sioplas silane cross-linking extrusion technology, the device effectively filters carbide impurities, unmelted particles and gel residues in XLPE melt. It ensures uniform plasticization and stable flow of silane cross-linked polyethylene materials, optimizing the grafting cross-linking effect during extrusion. With high pressure resistance and self-lubricating hydraulic system, it adapts to the long-term continuous operation of cable extrusion lines, avoiding bubble, impurity and uneven insulation thickness defects of finished cables.
Equipped with precise pressure and temperature adaptive control, the hydraulic continuous screen changer maintains consistent melt filtration accuracy in long-cycle production. It significantly improves the yield and qualification rate of XLPE cables, reduces production downtime and operation costs, and provides reliable process guarantee for high-efficiency and high-quality production of Sioplas XLPE wire and cable extrusion lines.
