Dongguan manufacturers supply single screw plastic extruder for PP PE PVC plastic pipe extruder
Product Description

The function and working principle of plastic extruder machine
Extruder is a common equipment for industrial production, widely used in plastic processing, fiber manufacturing, food processing and other fields. The main function of the extruder is to make plastic products with strong plasticity and stable performance through multiple steps such as high-temperature melting, extrusion and cooling molding.
The working principle of the extruder is that the plastic particles or sheets are heated to the melting point and then fed into the feed port of the machine, and the cylinder is extruded by a high-speed rotating screw, and the pressure control and other parameters are added at the same time. Then through the design and adjustment of the die head, the plastic cylinder is extruded into plastic products of various shapes and sizes.

Plastic extruder machine forming principle
The extrusion method of plastic extruder generally refers to the melting of plastic at a high temperature of about 200 degrees, and the melted plastic forms the required shape when passing through the mold. Extrusion molding requires a deep understanding of plastic characteristics and rich experience in mold design, and is a molding method with high technical requirements.
Extrusion molding is the method of making the material flow through the mouth mold continuously by heating and pressurizing in the extruder, also known as "extrusion". Compared with other molding methods, it has the advantages of high efficiency and low unit cost.
The extrusion method is mainly used for the molding of thermoplastics and can also be used for some thermosetting plastics. Extruded products are continuous profiles, such as tubes, rods, wires, plates, films, wire and cable cladding. In addition, it can also be used for plastic mixing, plasticizing granulation, coloring, blending and so on.
Extruded products can be called "profiles", because the cross-section shape is mostly irregular, so it is also called "profile"
Plastic extruder (host) can be matched with pipe, film, holding material, monofilament, flat wire, packing belt, extrusion mesh, plate (sheet) material, profile, granulation, cable coating and other plastic molding auxiliary machines to form a variety of plastic extrusion molding production line to produce a variety of plastic products.

Plastic extruder  machine application field
1.Plastic product manufacturing:
Extruders are widely used in the plastic manufacturing industry. It is usually used to produce plastic products of various shapes such as pipes, wire tubes, special-shaped materials, rackets, coils, etc. It works by melting the plastic by heating it and pressing it into the spiral drum of the extruder, and then pressurizing it into the desired shape in a mold. Extruders can achieve efficient, continuous, large-scale production, greatly reducing production costs and product manufacturing cycle.
In addition, the extruder can also produce a variety of crosslinked polyethylene, alloy plastics, special flat wire, polyester film and other plastic products. These products have excellent physical properties, weather resistance and corrosion resistance, and are widely used in construction, electronics, automobile manufacturing and other industries.
2.Building material manufacturing:
Extruders are also widely used in the preparation of materials in the construction field, such as PVC window frames, aluminum-plastic panels, plastic partitions, etc.
3.Agricultural field:
Plastic products made by extrusion mechanism are also widely used in agricultural production, such as agricultural film, thermal shed and other agricultural equipment preparation.

Suitable for the production of PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA and other plastic regeneration and color mixing materials. The reducer adopts the design of high torque, which realizes the performance of no noise and smooth operation. Screw, barrel after special hardening treatment, with wear resistance, mixing performance is good, high yield characteristics. The design of vacuum exhaust or ordinary exhaust port can discharge water and exhaust gas in the production process, and the particles are more stable and the colloidal particles are stronger to ensure the excellent quality of the products

The difference between twin screw extruder and single screw extruder is reflected

How materials are transported
In a single screw extruder, friction drag is used in the solid conveying section and viscous drag is used in the melt conveying section. The frictional properties of solid materials and the viscosity of molten materials determine the conveying behavior. If some materials have poor friction performance, if the feeding problem is not solved, it is more difficult to feed the material into the single screw extruder. In twin-screw extruders, especially meshing twin-screw extruders, the transfer of materials is to some extent a positive displacement transfer, and the degree of positive displacement depends on the proximity of the screw edge of one screw to the relative screw groove of another screw. The geometry of the screw of the tightly engaged cross-rotating extruder can obtain high forward displacement transport characteristics.

Flow velocity field of material
At present, the flow velocity distribution of the material in a single screw extruder has been described quite clearly, but the flow velocity distribution of the material in a twin screw extruder is quite complicated and difficult to describe. Many researchers just do not consider the material flow in the meshing zone to analyze the material flow velocity field, but these analysis results are very different from the actual situation. Because the mixing characteristics and the overall behavior of the twin-screw extruder mainly depend on the leakage flow in the meshing zone, the flow situation in the meshing zone is quite complex. The complex flow spectrum of the material in the twin screw extruder shows the advantages that the single screw extruder can not compete in the macro, such as sufficient mixing, good heat transfer, large melting capacity, strong exhaust capacity and good temperature control of the material.
