Production line structure and process characteristics of plastic sheet

Plastic sheet production line, as its name implies, is a production line equipment that uses plastic as the main raw material to produce plastic sheet. Its raw materials include almost all plastics, such as PVC, PP, PE, PC, ABS, HIBS, etc. Plastic plate has the unique advantages of plastic polymer materials, such as light weight, corrosion resistance, beauty, innocuity, tasteless, no corrosion, aging resistance, and weather resistance.

Generally, the plastic plate production line is composed of mold, sizing sleeve and cooling device shunt support, mold body, mandrel and forming die.

The general production process of plastic sheet production line is as follows:

1. Preheating of plastic plate production line: This is to make the mold heated before starting up, and the mold should be closed for heating.

2. Mold closing: reasonable adjustment of mold opening and closing stroke is conducive to improving product demoulding and product feeding effect.

3. Preheating of plastic plate production line: steam enters the fixed moving die to preheat the mold.

4. Penetration heating: improve the fusibility of the core and interior of the products. Penetration heating consumption and steam waste are serious.

Characteristics of plastic sheet production line:

High degree of automation, convenient operation, continuous production, stable and reliable.

The three roller calender of plastic sheet production line can be lifted and lowered freely.

The plastic plate production line has independent control roller temperature control system, which can accurately control the temperature of the press roller, so that the plate thickness is uniform.

The thickness control of plastic plate production line adopts screw adjustment and press wheel bidirectional adjustment to control plate thickness.
