We constantly committed to the development of plastic extruder screw, to meet the demand of terminal customers, reduce cost and prolong the service life of the screw, to create the largest profit, newly developed a new type of super wear-resistant corrosion-resistant screw a tungsten carbide screw, compared with the existing metal screw on the market at present.Double the service life of the screw in its original use time.Special needle in engineering plastics contain glass fiber, mineral fiber, stone powder, magnetic powder, iron powder and other additives high in the situation, can greatly reduce the frequency of replacing the screw.
