Bimetallic Conical Twin Screw Barrel for Extruder

    Bimetallic conical twin barrel has got the nation patent,and we are the only company in manufacturing the bimetallic conical twin barrel.Adopting the technique of rotary casting alloy,it makes the alloy powder’s compactness and wearing resistance the same as the bimetallic single barrel thus solving the defect of short service life and low wear-resisting of nitrided conical twin barrel,and rewrite the history of only manufacturing bimetallic single barrel but no bimetallic conical twin double barrel in domestic land.    Wc-10 tungsten carbide alloy ,with the characteristics of high hardness ,high hard-wearing and corrosion resistance ,and high temperature resistance ,the hardness of alloy layer reaches HRC60-65,thus having the service life of 5-8times longer than the nitrided one.It is suitable for processing PVC plus calcium powder,building plastic template, pipe, sheet, ,WPC , hanging plate and other engineering plastics.    Grade A screw: the base material is SKD61,Din…
