Production process and structural characteristics of plastic sheet production line

- Dec 04, 2018-

The plastic sheet production line, as its name implies, is a production line equipment for producing plastic sheets with plastic as its main raw material. Its raw materials include almost all plastics such as PVC, PP, PE, PC, ABS, HIBS, etc. Plastic sheets have the unique advantages of plastic polymer materials, such as light weight, corrosion resistance, aesthetics, non-toxic, odorless, non-corrosive, anti-aging, weather resistance and so on.


Generally, the plastic sheet production line consists of a mold, a sizing sleeve, and a cooling device shunt bracket, a mold body, a mandrel, and a forming die.


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

1. The plastic sheet production line is preheated: this is to make the mold heat before the start-up, and it needs to be preheated to mold heating.

2. Clamping: Reasonable adjustment of the opening and closing stroke is beneficial to improve the demoulding of the product and the effect of product feeding.

3. Preheating of plastic sheet production line: steam enters the solid transfer mold and preheats the mold.

4. Penetration heating: Improve the core and internal weldability of the product. The penetration heating and waste steam are more serious.


Features of plastic sheet production line:

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

The three-roll calender of the plastic sheet production line can be lifted freely.

The plastic sheet production line has an independently controlled roller temperature control system that precisely controls the temperature of the pressure roller to make the sheet even and uniform.

The thickness control of the sheet produced by the plastic sheet production line uses screw adjustment and two-way adjustment of the pressure wheel to control the thickness of the sheet.
