Process flow of PVC foam board extrusion line:

PVC resin + additives → high-speed mixing → low-speed cold mixing → conical twin-screw extruder → mold (skin foaming) → cooling structure shaping machine → multi-rubber roller tractor → cutting machine → finished product collection and inspection
In addition, the customer can also produce A+B+A three layers co-extrusion foam board by adding extruder and distributor .The machine should equip with water chiller, can increase production efficiency.
