Product Description Bimetallic Barrel 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 ParametersProduct Name : Bimetallic BarrelMaterial: JYN3 + JYK Series AlloySuitable Machine: Injection / Extrusion / Blowing ...Available Size: Φ < 500mm, L < 8,000mmProcess Method: Centrifugal CastingSurface Hardness: 52-62 HRCSurface Roughness: < Ra 0.8Screw Straightness: < 0.02mm/mAdvantagesBy 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 AlloyAt this stage, we have JYK-1, JYK-2 and JYK-3 alloy types and treatments for wear fighting TYPECOMPONENTSHARDNESS(HRC)AbrasiveRESISTANCECorrosionresistanceapplicationsJYK-1, CFe, Cr, Ni56 - 60xxRecycling & engineering plastics, reinforced additives less than 20%.JYK-2, BNi, W, Cr58 - 62xxxxModerate corrosive, reinforced additives less than 35%JYK-3, DNi, W, Cr60 - 64xxxxxHigh abrasive and moderate corrosive plasticsSuitability: (x good) to (xxx excellent).
