The screw of the extruder is assembled by a barrier unit and a mixing unit, and the barrel has a unique grooved structure in order to achieve the effect of plasticizing and mixing. HDPE large-diameter pipe adopts the special design of blue mold, which reduces the dissolution temperature and the pressure of the host to achieve a good mixing effect, thereby ensuring the output.
HDPE原料，都适合上述原料的冷却。 The unique design of the cooling and sizing system, using water circulation to cool HDPE raw materials, are suitable for the cooling of the above raw materials. The unique design can improve the stability and roundness of the diameter and meet the needs of thick-walled pipe production.
The special design of the vacuum sizing box can ensure the stability of the diameter and roundness, and the speed control system makes the traction speed stable. PLC控制，液晶屏幕控制面板，操作简便。 The entire production line adopts PLC control and LCD screen control panel for easy operation. Can be equipped with color labeling extruder to make the tube with color labeling line
