Key Steps in PVC Pipe Extrusion

1. **Material Feeding**: High-precision hopper with auto-calibration (e.g., ±0.5mm tolerance).  

2. **Heating & Melting**: Twin-screw extruder with 5-zone temperature control (120-220°C).  

3. **Molding**: Customizable die heads for 20-630mm pipes (seamless or ribbed designs).  

4. **Cooling & Cutting**: Water-cooling system + laser cutting (±0.1mm precision).
