PVC production line technology encompasses core stages such as raw material processing, extrusion and plasticization, vacuum sizing, and cooling/cutting. Process parameters vary significantly based on pipe diameters (e.g., 20–63mm, 75–250mm, 315–630mm, 630–1200mm for drainage or water supply pipes) and materials (rigid PVC, PVC-C). The core technical focus of PVC multi-layer co-extrusion pipe lines lies in ensuring material compatibility, maintaining uniform layer thickness, and achieving high-speed synchronous control. By merging molten materials with distinct properties within a composite die head, the resulting pipes combine functionalities such as barrier properties, strength, and corrosion resistance; these are widely used in applications like oxygen-barrier pipes, aluminum-plastic composite pipes, and large-diameter sewage pipes. Core Process Flow and Key Technical Data PVC pipe production typically employs a conical twin-screw extrusion process. The standard workflow is: raw ma...
