1. The PVC Corner extrusion line has been improved from the original One-out-of-Two to One-out-of-Four & One-out-of-Six extrusion line, which increases capacity but reduces labor costs;
2. The old-fashioned punching machine of PVC Corner extrusion line has been improved to high-speed punching machine (easy to operate). Products are not easy to break during the production process, and processing is stable and more power-saving;
3. PVC corner production line consists of twin-screw (or single-screw) extruders, customized moulds, vacuum stereotype table, specialized hauling-off machine, high-speed punching machine, and automatic stacking machine (new type of machine).

Production Process Raw Material + Additive Preparation (Formula) → Mixing ( Mixer Unit) → Loading (Screw Loader) → Conical Twin-Screw Extruder → Customized Mould → Vacuum Stereotype Table → Specialized Hauling-off Machine → Punching Machine → Automatic Stacking Machine (PLC control)
