Double Alloy Extruder Screw Barrel

Product Introduction:

Alloy screw adopts cemented carbide material, cemented carbide material itself has high wear resistance, high hardness, high temperature resistance and other comprehensive performance, under normal circumstances, the service life is more than 10 times of the general alloy steel. Combined with our advanced processing equipment and processing technology, the production has good cross section crack strength, while producing a lot of cutting heat and other harsh working conditions are still free from the impact of corrosion, for your machine to bring excellent production efficiency.

The whole screw adopts multi-section splicing structure, and the glue head and screw are also separately produced, and then assembled into one, so as to improve the strength of the glue head and screw, increase the high temperature wear resistance of the glue head and screw, greatly improve the service life of the whole screw, especially the use of multi-section combination screw sleeve, and the combination structure of multi-section combination screw sleeve and separate glue head, Can be in a certain section of the screw sleeve, or glue head damage, just remove the glue head, can be replaced, easy to disassembly and maintenance.

Zhoushan Jed Machinery Co., Ltd. is located in the hometown of screw in China, the largest production base of screw and barrel in China, and the beautiful scenery of Yancang Industrial Zone, Dinghai District, Zhoushan city, Zhejiang Province. It is a professional manufacturer of extruder XPS foaming board screw, injection molding machine precision sol-barrel, parallel screw, conical screw, building block type screw barrel and accessories. Our company has a complete product design team, introduced a number of sets of advanced production technology equipment and testing instruments, and established a sound quality control system. The production process strictly selects high quality alloy steel as raw material, advanced technology, fine processing, the use of testing equipment, to ensure the accuracy and quality of products, with a long service life and good wear and corrosion resistance and other characteristics.

Our company carries out surveying and mapping, design, maintenance and renovation of batch processing business, make full use of advanced screw design and technology, to provide customers with cost-effective products. We can not only make samples, but also design, survey and manufacture according to the special requirements of customers, and use bimetal repair work for old screws. The service life of bimetal screws is 1-3 times higher than that of ordinary nitride screws.

Welcome new and old customers to negotiate consultation and exchange guidance, your satisfaction is our eternal pursuit and goal! Customized hotline/WhatsAPP: +8613567672668 wechat same number.

Product Type:

Common type, gradual type, mutation type, mixing type, separation type, pin type, exhaust type, barrier type, shunt type, wave type, acceleration type.

Product Features:

1, wear resistance, long life;

2,high temperature resistance, no deformation at high temperature;

3, corrosion resistance, the material is corrosive;

4, good cutting performance;

5, high strength, can withstand large torque, high speed;

6,Small residual stress and small thermal deformation after heat treatment.

Daily maintenance:

1,do not start the machine when the screw does not reach the preset temperature.

2, prevent metal debris and sundry into the hopper, if processing recycling material, it is necessary to add a magnetic hopper to prevent iron chips into the barrel.

3, the use of anti-saliva to determine the plastic melt in the barrel, so as not to damage the transmission system parts when the screw recsliding.

4, the use of new plastic, should be the screw residual material clean.

5, when the temperature of the molten plastic is normal but the molten plastic is constantly found to appear black spots or color change, should check the screw.

6, in the processing, try to make the material plasticizing uniform, do not let the metal foreign body mixed in the material, reduce the screw rotation torque force.

Scope of Application:

Injection molding machinery, extrusion machinery, blow molding machinery, film blowing machinery, granulation machinery, wire and cable manufacturing and other industries. Suitable for spinning, granulation, drawing, film blowing, extrusion tube, foaming, extrusion sheet, extrusion board, etc. Used in central air conditioning, household air conditioning and construction, chemical industry, metallurgy, shipbuilding, medicine, vehicles and other industries of all kinds of hot and cold pipes, container insulation, heat insulation and other new generation of high-quality insulation materials products.
