JYS1 Bimetallic Screw for Processing Rigid PVC Grannule  

Bimetallic Screw   PTA (Plasma Transferred Arc) automatic alloy spaying is a newly applied technology, especially for precise requirement of screws. Comparing to traditional manual alloy spraying, PTA has better performance with the stability and outlook of screws. Technical Parameters Product Name : Bimetallic Screw Material : JYN1 + JYS Series Alloy Suitable Machine: Injection / Extrusion / Blowing ... Available Size: Φ14-400mm, Length <8,000mm Process Method: PTA Spray Surface Hardness:46-58 HRC Surface Roughness: < Ra 0.8 Screw Straightness: < 0.02mm/m   Advantages By spraying high quality alloy powder on screw flight with layer thickness 1.5-2.0mm, screws can get higher performance in both wearing & corrosion resistant performance.   Application  General plastics & engineering plastics with below 15% glass fibre filling.   JYS S…
