For bimetallic screw ,we have adopted advanced technique(HP/HVOF)of surface harden Process by the whole screw surface,WPT1 alloy with corrosion resistant suits for nylon,PVC,PC,PMMA and so on.WPT2alloy corrosion resistant and high temperature resistant Suits for magnetic power ,maanetic powder,magnesium and alumimum powder.Bakelite injection and so on .WPT3 is compatible with WPT1 and WTPT2. Technical Parameters The main advantage of screw barrel: Why choose us ?  A> long time experience and history B> long time nitriding treatment and heating treatment by itself C>advanced Fanuk series CNC computer-controlled milling machines D>depth hole drilling machine in 10meters length, which ensure the straigtnss of barrel inside. E> CAD drawing confirmation before start making F> Prompt after sale service  G>Land owner and registration capital 25,000,000RMB Zhejiang pinbo plastic machinery co.,ltd is located in ruian wenzhou city with brand of PYM (Former Ruian yumin machine screw co.ltd since 1988). The company is specialized in making screw barrel, gearbox zlyj series, t die, filter and extruder machine. It has become one of the largest supplier of main parts in Ruian city which is the basement of plastic machines.  It owns many computer-control CNC milling machines in length 8000mm In Fanuk series, 18000mm length deep hole drilling machine and other advanced equipment. Long time nitriding treatment for 7days and nights greatly ensure the hardness and lifetime of its products. Meanwhile, the company and its products have passed assessment by SGS company, Bureau of Veritas, Tuv and Ce certificate.   For bimetallic screw ,we have adopted advanced technique(HP/HVOF)of surface harden Process by the whole screw surface,WPT1 alloy with corrosion resistant suits for nylon,PVC,PC,PMMA and so on.WPT2alloy corrosion resistant and high temperature resistant Suits for magnetic power ,maanetic powder,magnesium and alumimum powder.Bakelite injection and so on .WPT3 is compatible with WPT1 and WTPT2.

Carbon steel is a metal alloy of carbon and steel. There are four types of carbon steels, ranging from low to very high, that are classified by the amount of carbon they contain. Carbon steel forgings exhibit strength, hardness, ductility, and impact resistance.
