PVC Foam Board Production Line

The lines have the advantages of well-planned layout, compact in structure, fine in performance such as homogenous plasticization, high output and long service life. The screws and barrels are made of special alloy and the structure is optimized. Exchanging screen rapidly about 1.5 seconds every times, the screen changer unit don't need the downtime. The cutting unit can guarantee the precise measurements through the adjustment of length and width, the error of product's diagonal<3mm, the using range of products is wide. The line can adopt one, two, three extruders together to do one layer, multi-layer plastic sheet. The electric control system utilize imported frequency converter, it's safe and reliable.

1.It is composed of extruder, three-roller calender, traction,rewinding and electric control box.

2.The screw, material barrel, screenchanger, measurement pump, die head are made of high quality alloy steel (38CRMOAIA) with high hardness, strong corrosion resistance and long operating life after nitrogen treatment.

3.The die head adopts hanger-type branch pipe decreasing-style construction, so the flow passage is convenient for material solution to flow without stagnation and the thickness of products will be smooth and even.

4.Insiede the calender the helical flume and cycle water cooling bring a perfect cooling effect.

5.The temperatures of die head, screen changer the measurement pump and the material barrel are separately controlled.

6.All drive system runs synchronously

Feature of finished products

1. Have a good physical performance, durable time is some times longer than wood products.

2. Light, cheap, good processing performance, wearable and good plasticity.

3. Vermin proof, antibiotic, corrosion resistance, no absorbing and hard transmutation.

4. Ultraviolet radiation resistance, weather bearing, heat insulation and have a similar texture with wood, besides, it has a good stainability.

5. Have a stable performance.
