Equipping a gear pump in front of the extruder, checking pressure before the pump and contolling the speed of extrusion, which can minimizing pulsation and iregular material feeding and ensures the polymer is smoothly extruded and continuously delivered to the die head. The system can be widely used to measuring and adding pressure for PC, PMMA, ABS. PET, PVB, PS, PP, PE. The shell of the pump adopts high-quality aloy-steel and the gear uses quenched chrome steel or other high-grade metallic materials which ensures high eficiency and leakage-proof.

We produce not only a variety of single-layer/multi layer co- extrusion dies su itable for materials including PC, PMMA, AP- _ET, PETG, ABS, PS, HIPS, PVC, PP, PE, PU, EVA, PVDC, but also other products such as high transparency panels, color panels, foaming sheet, hollow sunshine . boards, sanitary ware sheet, aluminum-plastic composite panel, water-prooof coils, special floor leather and various materials for food, clothes and medicine package, sheet materials for staionery, light fim, graining film. coating film and so on.
