Plastic Extrusion

Our factory is engaged in the research, development and production of complete plastic pipe extrusion and related equipment. Our factory insists on the quality oriented, our quality inspection team supervises every production link, and ensures that each set of equipment is tested in accordance with the voltage, frequency and safety standards of the destination country or region before leaving the factory.

In recent years, Meenchi machinery has continuously introduced advanced technology and management methods from all over the world on the basis of its own technology. Its products are: plastic pipe production line: PE corrugated pipe extrusion line, pvc pipe extruder machine out of four, pvc pipe extrusion line out of two,cpvc pipe making machine ,hdpe pipe extruder machine, pe pipe extrusion machine, ppr pipe extrusion machine, PE-RT pipe production line, pvc conduit pipe machine, PC pipe line, high-speed mixing unit, planetary cutting machine , three claw tractor and other auxiliary equipment.

The twin-screw extruder is composed of driving device, feeding device, barrel and screw. The function of each part is similar to that of single screw extruder.

The twin-screw extruders used for profile extrusion are usually closely meshed and rotating in different directions. Although a few of them also use the same rotating twin-screw extruders, they are generally operated at a relatively low screw speed, about 10 R / min. The high-speed intermeshing co rotating twin-screw extruder is used for mixing, exhausting or as a continuous chemical reactor. The maximum screw speed range of this kind of extruder is 300-600r / min.

The profile plasticizing extrusion is a kind of extruder for profile without special structure, as long as the general extruder is selected correctly. When selecting extruder, only single screw extruder can be selected; when the profile section is large, the profile section size is different. When the weight of profile per meter is not more than 250g, PVC powder resin can be used in single screw extruder or twin screw extruder in advance. When single screw extruder is used for molding, granulation is carried out. The twin-screw extruder can directly use PVC resin with simple mixing, and the conical twin-screw extruder with different rotation is generally used for molding.

Profile can be divided into two types according to material, one is all plastic profile, the other is composite profile made of plastic material and non plastic material. According to the soft and hard degree of different profiles, they can be divided into soft profile and hard profile. According to the classification of plastic varieties, it can be divided into PVC profile and PE profile, most of which are PVC profile. The extrusion process of plastic profile is very similar to that of pipe. Take PVC as an example to introduce the difference between profile and pipe.

Single screw extruder is mainly used to extrude soft, rigid PVC, polyethylene and other thermoplastic plastics. It can process a variety of plastic products, such as blown film, extruded pipe, pressing plate, drawing ribbon, etc., and can also be used for melting granulation.

The plastic extruder is advanced in design, high in quality, good in plasticization and low in energy consumption. It is driven by involute gear and has the characteristics of low noise, stable operation, large bearing capacity and long service life.
