The PVC/PP sheet & board extrusion line mainly consists of core units including single/twin‑screw extruder, extrusion die, three roller calender, calibrating system, cooling and haul‑off unit, edge‑trimming & guiding mechanism, cutting machine and stacking rack. Capable of continuous extrusion of various polymer materials such as PVC and PP, this line produces plastic sheets and boards in different thicknesses and widths, featuring uniform thickness, smooth and glossy surface, and stable physical properties.

The machine adopts optimized screw and barrel structure to deliver even plasticization, high extrusion output and lower energy consumption. Equipped with a precision coat‑hanger die with well‑designed flow channel, it ensures stable material discharge without streaks or bubbles. The three roller calendering and calibrating system precisely controls the flatness and thickness tolerance of boards. Combined with the continuous cooling system, it enables rapid product sizing with low internal stress, effectively improving product flatness and finished‑product rate. The whole production line is fitted with intelligent control systems such as automatic guiding, variable‑frequency speed regulation and fixed‑length cutting, featuring stable operation, easy operation and high automation level.

The produced PVC/PP sheets and boards boast good toughness, high impact resistance, corrosion resistance, waterproof and moisture‑proof performance and easy process ability. They are widely applied in industries including packaging materials, stationery boards, advertisement & decoration, plastic hardware, food packaging, industrial base plates, building decoration and medical device accessories. It is a mainstream complete set of equipment in the plastic board processing industry.
