Large Caliber U-Pvc Extrusion Line U-Pvc

The large-diameter U-PVC extrusion production line uses U-PVC resin as the main raw material. First, the mixing system fully mixes the resin with additives such as stabilizers and plasticizers to form a uniform material mixture. Then the mixture is transported to the extruder, where it is heated, melted and plasticized in the extruder barrel to form a molten PVC melt. Driven by the thrust of the screw, the melt is continuously pushed to the mold, and the initial shape of the large-diameter pipe is formed through the specific cavity of the mold. Next, the formed pipe enters the cooling and shaping system, and is rapidly solidified and shaped by spray cooling or vacuum cooling. Finally, it is pulled at a constant speed by the tractor and cut into the set length by the cutting equipment, completing the continuous production of large-diameter U-PVC pipes.​

This production line has a high degree of automation, which can realize continuous operation from raw material mixing to pipe cutting, reducing manual intervention and improving production efficiency. It has strong equipment adaptability: by replacing molds of different specifications, it can produce U-PVC pipes of various diameters to meet the needs of different scenarios such as municipal engineering and water supply and drainage. The production line adopts a precise temperature control and shaping system, which can ensure uniform pipe wall thickness and flat appearance, improving the stability of product quality. In addition, key components are made of wear-resistant and high-temperature-resistant materials to extend the service life of the equipment; it operates with low noise, causing little interference to the working environment; at the same time, raw material waste can be reduced by optimizing the process, lowering the production cost.
