Injection molding machine accessories series:
Professional equipment, precision production, all kinds of screw barrel are made of high quality alloy steel 38CrMoALA manufacturing, product after nitriding by the anion has a very high wear and corrosion resistance, and increased life expectancy and so on, can replace imported products. Strict implementation of the technical indicators are "JB/T8538-1997" and the ISO9002 standards.
Screw can choose different screw head, barrel can choose the appropriate nozzle. Mainly used in plastic molding machines and extrusion machines for plastic range: ordinary plastic, PP, PE, ABS, AS, PS and so on.
