UPVC Pipe Ring Cutting Machine Manufacturers

How to Choose Quality Plastic Extrusion Line from Reliable Manufacturer Before you choose your machine, consider the following tips:

Parallel twin-screw extruder and conical twin-screw extruder can be used to directly produce PVC-U pipe with dry powder. Due to the full engagement of two screws, a closed C-shaped chamber is formed in the twin-screw extruder. The two screws rotate outward in different directions to make the C-shaped chamber move forward axially, so it has the function of forced conveying (positive displacement conveying) of materials; There is a speed difference at the engagement between the screw edge and the screw groove, which forms an extrusion and grinding effect on the material, which is conducive to the plasticization of the material. At the same time, the material adhered to the screw is self-cleaning, and the process experienced by the material in the barrel is relatively close to avoid local material degradation due to overheating.

Congratulations! On Dec. 22nd, the PE large-diameter anti-melt sagging thick-walled pipe extrusion equipment passed the customer's on-site acceptance. Pipe size in the picture is O.D 1200mm，SDR13.6.

Screw is a core component of plastic extruder equipment, which needs to directly contact with plastic raw materials and withstand long-term high temperature, high pressure, and high shear working environment. Therefore, our factory has very high standards for the quality of screws. For the production of different plastic products, we have different requirements for screws. However, there are still basic manufacturing quality requirements for screws, as follows:

Sales of primary plastics machinery in North America rose in the third quarter of this year – in comparison with the same period in 2021.

Pipe cutting methods can be generally divided into two kinds: manual cutting and automatic cutting. When the diameter of pipe is small (within 50 mm), many manufacturers will use saw to cut by hand in many cases. But now, in order to improve the production efficiency and ensure the length accuracy of plastic pipe, the extruder production line will also be equipped with automatic cutting machine.
