extruder screws and barrels,
injection molding machine screw
Shaft for Coperion STS75
Screw barrel adapt high quality 38Cromaia raw material and due to different plastic material , screw barrel can spray bimetallic treatment which with more long service life. The bimetallic treatment of our screw by the PTA machine. It is a advance equipment which has not been broadly used in bimetallic treatment. Compare to the manual process the advantage is better temperature stability, dense structure and uniform thickness and not liable to crack. The bimetallic barrel is centrifugally cast a 2~4mm thick alloy coat on the output section of barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided barrel. Bimetal has more obvious advantages when processing high calcium carbonate powder PVC mixture to enhance the abrasion life.
General’s Spline design, made of high alloy steel, reduces stress concentration. Shafts are made of round steel-40CrNiMo.Shafts made
of round steel- 40CrNiMo with great heating treatment have highly hardness(HV>30)and torque.,attached isshafts for Coperion STS75.
a. Cost advantage: mature scientific processing technology and heat treatment process to produce high-quality thread components, barrels, to replace imported products, to reduce costs for customers.
b. Advantages of foreign trade: Many well-known enterprises at home and abroad extruder screws are manufactured by customers and serve for many years. SABIC, LG Chem, Guangdong Hyundai, Tianjin Samsung, Formosa Plastics, DuPont, and Shanghai Toyoink are all cooperative customers. Can make a presentation, such as the company's gift, reflected in About US.
c. Manufacturing advantages: at the top of domestic production level, to meet the production standards of Japan and Germany. Strict product quality inspection procedures
d. Time cost advantage: the product itself can be customized according to customer needs, and the delivery time is short, the cycle is flexible and efficient.

Scope of application
WPC sheet,pallets,pinch,pipe,profiles,soft pvc,pvc foam sheet,film,tape,recycled,tape tube,water pipe,drainage pipe,etc.
For good plasticizing effect,we have different designs of screw and barrel for extruder or injection to meet customer's demand. Our factory manufactures with high-quality material, applying the method of hardening and tempering and nitriding, thus it enjoys the characteristics of long working life, wear resistance, and anti corrosion. Besides, the technique of hard alloy spraying or chrome plating can be used on the working surface of screw, which will make it have better using effectiveness.
All dimensions including out diameter, Hole size tolerance, Root diameter,Parallelism of end surface,Verticality are in accordance with technical data.
