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 ParametersProduct Name : Bimetallic ScrewMaterial : JYN1 + JYS Series AlloySuitable Machine: Injection / Extrusion / Blowing Available Size: Φ14-400mm, Length <8,000mmProcess Method: PTA SpraySurface Hardness:46-58 HRCSurface Roughness: < Ra 0.8Screw Straightness: < 0.02mm/mAdvantagesBy 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 Series AlloyAt this stage, we have JYS-1, JYS-2 and JYS-3 alloy types and treatments for wear fighting.
