According to customer preference, our PVC pipe production line can be equipped with a conical twin-screw extruder or parallel twin-screw extruder. The extruder is equipped with a quantitative feeding system, which can be controlled by frequency conversion and speed control, and is equipped with fault alarm and overload protection functions. It has the advantages of large extrusion volume, small shear rate, and difficult decomposition of materials.
The screw design of the twin-screw extruder is scientific and reasonable. The screw has undergone fine treatments such as nitriding and high-frequency quenching to ensure good mixing and plasticizing effects, and full exhaust. The core temperature control device equipped with the screw can better control the processing temperature of the material.

Blesson PVC pipe mold can produce PVC pipes with various diameters from 16mm to 1000mm.
The PVC pipe mold designed by Blesson adopts a shunt shuttle bracket type die, with an optimal runner design, and an easy-to-disassemble mold structure to ensure the plasticization effect of PVC, improve the flow performance of the material, and the user can change the mold and adjust the center height and horizontal angle of the mold according to the actual production requirements.
In terms of the mold manufacturing process, our molds are made of high-quality mold steel, which is manufactured through forging, rough machining, quenching and tempering treatment, runner surface rough polishing and fine polishing, mechanical finishing and hardening, and anti-corrosion treatment. The standardized manufacturing process ensures that the mold has good material stability and wear resistance and corrosion resistance. The plastic also has good fluidity in the mold.

The vacuum tank adopts the most advanced water supply and drainage integrated structure to ensure that the pipeline is clear, which greatly reduces the difficulty and time of installation and maintenance. The vacuum tank body, pipelines, pipeline fittings, etc. are all made of high-quality SUS304 stainless steel, which significantly improves the anti-corrosion durability. The heavy cast aluminum cover and the three-layer rubber ring on the vacuum tank ensure better sealing. The high-precision water ring vacuum pump ensures a stable and effective shaping of products. The tightly arranged sprinklers and stable water pressure improve the speed and uniformity of pipe cooling. Precise water level control and water temperature control further improve the quality of PVC pipe cooling and shaping. The large-capacity water filter and backup bypass can effectively clean impurities in the cooling water, and can quickly clean the filter without stopping the machine.
