Decoration Application PVC Sheet Production Line Introduction: This PVC Sheet Extrusion Line is composed of conical twin screw extruder, double station hydraulic screen changer, melt pump, extruding mould, three-roller calender, cooling conveying device, lengthways trimming device, film-covering device, haul-off machine, crosscutting machine, sheet stacker. The extruder adopts conical twin-screw type. The screw structure is specially designed for PVC Sheet Extrusion Line, it ensures high efficiency plastifying and uniformity. The barrel uses fan-cooling on heating zones, and water cooling through copper pipe wrapped on its front body. The barrel is equipped with vacuum and drying device to ensure the material quality.
| Material | Nitriding depth | Hardness | Surface Roughness |
Screw | 38CrMoAlA | 0.5-0.6 mm | HV740-940 | Outer, Ra≤0.8μm |
Barrel | 38CrMoAlA | 0.5-0.7 mm | HV≥940 | Inner, Ra≤01.6μm |
Reducer has features of large power, high efficiency, compact structure, stable transmission, low noise. Gears and shafts are made of high strength alloy steel, gears undergo cabonizing, quenching, teeth-grinding to the standard of level ISO6. Extruding mould works with high precision, the material uses high quality alloy steel hard chromium plated.
