In most extruders, the screw speed is changed by adjusting the motor speed. The drive motor usually rotates at a full speed of about 1750rpm, which is too fast for an extrusion screw. If it rotates at such a fast speed, too much friction heat will be generated, and the uniform and well stirred melt ......
Read MoreDepending on the pressure and shear force generated by the screw drive, the screw extruder can fully plasticize and evenly mix the materials, and form them through the die. Plastic extruders can be basically divided into twin-screw extruders, single screw extruders, uncommon multi-screw extruders an......
Read MoreSingle screw extruder shall be selected for the production of Po pipes. Axial slotted barrel is used in the feeding area. The screw length is 30~36d. The screw structure is two-stage deep variable pitch screw. The screw pitch in the feeding section is less than the screw diameter, and the screw pitc......
Read MorePE pipe production line is composed of control system, extruder, head, setting cooling system, haul-off, planetary cutting device and turnover frame. Each pipe production line has two extruders, one of which mainly adopts strong conveying bushing and screw, and the other smaller extruder is used to ......
Read MoreThe screw of the extruder of PE pipe production line adopts barrier structure, and the barrel has a unique groove structure, so as to achieve good plasticization and mixing effect. HDPE (PP, ABS) large-diameter pipes adopt the special design of basket mold to reduce the dissolution temperature and h......
