Product Group: extruder Product Description1) High efficiency and output 2) Low energy consumption 3) Applied in manufacturing PP, PE, PPR pipes Feature: High precision gear box, high carrying capacity, steady driving, low noises. Newly designed barrel and screw ensure better melt uniformity, low melt temperature and much higher production. For most applications, standard nitrided steel is used for barrels and screws with high corrosion-resistant. The unusual material can be processed by choosing two species of metals. The PID meter made in japan keep the temperature steady and accurate. The die head have two types: Manual swing and hydraulic pressure Screen-changing is easy and finished within a few minutes.
