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

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 Series Alloy
At this stage, we have JYS-1, JYS-2 and JYS-3 alloy types and treatments for wear fighting.
