Principle of PE pipe line production

The plastic pipe extrusion molding process is divided into three stages:

1. Raw material plasticization, which means PE/PP/Other Additives together are passed through the heating and mixing of the extruder, then the solid raw material becomes a uniform viscous fluid;

2. Forming Process, under the action of the extruded parts of the extruder, the molten material is continuously passed through the forming head at a certain pressure and speed to obtain a certain cross-sectional shape;

3. Cooling and shaping, that is, through sizing and cooling treatment methods, the molten material will fix the obtained shape and turn it into a solid state (plastic pipe).

The above three stages are realized by the main engine and auxiliary engine, or extruder unit. Specifically, the main machine is the extruder, and the auxiliary machine includes the die head, the shaping device, the cooling device, the traction device, the cutting device and the stacker.
