Centrifugal casting or rotocasting is a casting technique that is typically used to cast thin-walled cylinders. It is chiefly used to manufacture rotationally symmetric stock materials in standard sizes for further machining, rather than shaped parts tailored to a particular end-use.
Technical Parameters
Product Name : Bimetallic Barrel
Material: JYN3 + JYK Series Alloy
Suitable Machine: Injection / Extrusion / Blowing ...
Available Size: Φ < 500mm, L < 8,000mm
Process Method: Centrifugal Casting
Surface Hardness: 52-62 HRC
Surface Roughness: < Ra 0.8
Screw Straightness: < 0.02mm/m
Advantages
By casting and sintering high quality alloy powder on barrel inside surface with thickness1.5-2.0mm, screws can get higher performance in both wearing & corrosion resistant performance.
Application
General plastics & engineering plastics with below 70% glass fibre filling.
JYK Series Alloy
At this stage, we have JYK-1, JYK-2 and JYK-3 alloy types and treatments for wear fighting
