Shaft for Coperion STS75

 

Gradual change type screw features: compression section is long, accounting for 50% of the total length of the screw, the plasticizing energy conversion is moderate, mainly used for PVC and other plastic with poor thermal stabilityMutant screw features: the compression section is short, accounting for about 5%~15% of the total length of the screw, mostly used for polyolefin, PA and other crystalline plastics. Universal screw features: adaptable universal screw, can adapt to a variety of plastic processing.

 

Screw by using hard alloy material, will take more paragraphs joining together with the screw structure, and separate points glue head and screw, and then pack as a body, it can not only improve the glue head and the strength of the screw, increasing the rubber head and high temperature wear resistance of the screw, can greatly improve the service life of the screw, especially the multiple segment combination screw sleeve, and multistage screw sets of composite structures with separate plastic head, can be in a certain period of screw set, or rubber head appeared damaged, simply glue head off, can be replaced, portable maintenance.

 

 

Description:

We are the first screw element manufacturer in China, with more than 20 years' manufacturing experience, our screw element,barrel, shaft are produced by HIP material import from Germany to be same anti-wear& anti-corrosion , our customer including Europe extruder manufacturers, and world’s leading polymer compounders like Aschulman,Polyone,Covestro,DSM enginering plastic ,Lanxess.

Any questions,please feel free to contact us.

 

Specifications:

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.

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.

 

Competitive Advantage:

All dimensions including out diameter, Hole size tolerance, Root diameter,Parallelism of end surface,Verticality are in accordance with technical data.
