1. Cold feed extruder screw

Cold feed rubber extruder is an important equipment used in the rubber processing industry. It is currently widely used in the production and processing of tires, rubber tubes, sealant strips, wires and cables, waterproof materials and other products. The screw of cold feed extruder is a core component of such equipment, which determines the performance parameters of the extruder. As an advanced production form, the cold feed extruder often has a long body, and the length-diameter ratio (L/D) is about 8~20. Its plasticizing effect is good, the mixing is more uniform, and the extruded product is tight.

2. Hot feed extruder barrel

The barrel of the hot feed extruder is provided with a feed inlet and a discharge outlet. The barrel encloses the screw, while the screw operates in the barrel. When the screw rotates, it can push the material forward, heat is transferred to the material by the external heating of the barrel, and the volume of the screw is gradually reduced, so that the material is uniformly mixed and plasticized into a molten viscous flow state after being subjected to multiple forces such as extrusion, overturning and shearing, so as to complete the plasticization of the material.

Our company specializes in customizing and processing all kinds of cold and hot feed extruder screws, barrel and other products. The drilling barrel can control the temperature of each section independently, and has certain innovation in screw structure, which can complete the more difficult plasticizing, mixing and extrusion functions. Special dual-alloy barrel with high wear resistance is adopted, which has a long service life.

3. Hot feed extruder screw

Using the screw of the hot feed extruder to treat the material is better than the ordinary extruder equipment, its feeding is more smooth, it can effectively avoid the occurrence of jamming, and the exhaust effect during extrusion is also better.

Our company specializes in customized production and processing of various cold and hot feed extruder barrel screws, which are suitable for extruding various rubber products and providing rubber for calender, as well as for extruding rubber tubes, films, inner tubes, tread, wires, cables and filtering rubber impurities. Our company has some innovation in screw structure and other aspects. The screw has a special geometric structure, which can complete particularly difficult plasticizing, mixing and extrusion functions. The timing cylinder can also be used for separate temperature control of each section (drill barrel). The common screw is made of 38CrM0AIA material, and the surface is nitrided to ensure the torsion strength and wear resistance of the screw. The special alloy (centrifugal casting) bimetal barrel with high wear resistance is adopted, and its service life is longer than that of ordinary surface nitriding bushing or barrel.

4. Plastic extruder barrel

Our company can process and produce various types of plastic extruder barrel and supporting screw with inner diameter of 20~300mm (L/D=15~55). This product is generally made of alloy steel or composite steel pipe lined with alloy steel. It has the characteristics of good heat resistance, high strength, wear resistance and pressure resistance, corrosion resistance, solidity and reliability. With screw accessories, it can realize the crushing, softening, plasticizing, melting, exhaust and compaction of various plastics, And it can continuously and evenly deliver rubber to the molding system. The length of the barrel is generally 15~30 times of its diameter. The principle is to allow the plastic to be fully heated and plasticized.
