Product description: the screw barrel of Haitian injection molding machine is made of P1 all-alloy screw and all-alloy over-collet muon, which are made of P1 special materials (abrasion resistance, corrosion resistance, high temperature resistance and high pressure resistance). The surface roughness is less than 0.4um, the hardness can reach about HRC62 degrees, and the straightness of the screw can reach 0.015mm/M. K1 double alloy material tube: the inner hole centrifugal pouring K1 tungsten carbide alloy. Full alloy screw /K1 double alloy material pipe is suitable for all kinds of special engineering plastics forming.
Commercial use: full alloy screw /K1 double alloy pipe is suitable for all kinds of special engineering plastic molding.
