- Product Detail
In PVC pipe manufacturing, the counter rotating twin parallel screw barrel extruder is often used. It takes a dry mix of PVC and other auxiliary materials. The twin parallel screws turn the material into molten PVC, which is then shaped into pipes by moulds. Twin parallel screws are the core component that determines the quality of plasticised PVC and the stability of PVC pipe products. Our main clients are PVC pipe manufacturers, but we also supply spare parts to many extruder equipment machinery around the world.
PVC pipe twin parallel screw barrel
1. We have twin parallel screw barrels for PVC pipes. Screw barrels are made from high quality alloy steel 38CrMoAlA that’s tempered, precision machined, and nitrided for hardness and corrosion resistance. Each screw and barrel is machined using high precision CNC screw and barrel milling machines to ensure a high degree of consistency in extrusion performance. Screws and barrels have a smooth surface, and there are no gaps to gather material.
2. There’s a high level of corrosion and wear resistance on the screw barrel set. Bimetallic alloy anti-wear treatment is applied to the top surface of the screw flight in the compression, metering, venting, and mixing sections. The barrels can be supplied with a dual alloy groove surface strengthening process to make them more abrasion-resistant. Furthermore, we can provide a customised service for SKD sleeve fitted barrel.
3. We offer optimized screw designs that help mix the PVC pipe material well, increase plasticisation, improve extrusion volume, and provide good venting performance. In this way, you’ll get a great PVC pipe surface.
4. Our factory is equipped with a complete set of twin parallel screw barrel production processes, which allows us to produce large size twin parallel screw barrels potentially saving you production cost. Please contact us for the latest stock availability and screw barrel price on some screw barrel models.
