Equipped with polyolefin single screw extruder, it has the characteristics of high speed extrusion, acceleration, etc. Separated mixing screw for polyolefins. Special design of three co-extrusion dies, reasonable runner, smooth outer and inner wall of pipe, low internal stress. The production pipe diameter range is φ20-φ160mm, and the production speed is as high as 16 m/min. One multi-purpose machine can produce HDPE silicon core tubes, ordinary PP-R, PE, PEX pipes. Low cost: The cost of nano-antibacterial tubes is only 5-10% higher than that of ordinary tubes.
