Plastic Pipe Extrusion Molding Process And Future Trends

Plastic pipe extrusion molding process is divided into three stages：

1.  Plasticizing of raw materials, it means that the solid material is changed into a uniform viscous fluid by heating and mixing with an extruder.

2. Molding, under the action of extrusion parts of the extruder, the molten material is continuously passed through the molding head at a certain pressure and speed, so as to obtain a certain section shape.

3. Cooling finalize, that is, through sizing and cooling treatment methods, the molten material will be fixed to the obtained shape and become solid state (plastic pipe).

4. The above three stages are achieved through the main engine and auxiliary engine, or extrusion unit. Specifically, the main machine is the extruder, auxiliary machine includes the head, shaping device, cooling device, traction device, cutting equipment and stacking frame.

The market of new plastic extruders and production lines will develop in the direction of high technical content and low price. Domestic plastic extruder is now basically conical twin screw extruder and single screw extruder, the new high-end plastic extruder with mature technology has the advantages of high efficiency and high yield. This allows investors to get higher output and higher returns with lower input, but the precision of assistive devices and control systems must be improved. The wear of screw and barrel intensification requires the use of high wear resistance and ultra-high wear resistance material,speed reducer and bearing in mature high-speed operation to improve its life.
