Four-head PVC Win-door Seamless Welding Machine (AL-SHWS4-120*4500)
The SHWS4-120×4500 is a high-end four-head seamless welding machine for PVC/UPVC doors and windows. Designed for colored profile seamless welding, it can complete four-corner welding in one pass, delivering smooth, burr-free welds for premium-grade windows.
Overall Advantages
- Seamless Welding Technology: Removes welding flashes automatically after welding for smooth, invisible seams, ideal for high-quality colored profiles.
- Four-Head Simultaneous Welding: Processes four corners at once for maximum efficiency in mass production.
- Alloy Quenched Cutting Tools: High-hardness, interchangeable alloy tools for long service life and low maintenance.
- Rigid Welded Frame: Heavy-duty welded structure resists deformation, with automatic air blowing to clear welding debris.
- Precision Linear Guides: Heating plate moves on linear rails for stable, accurate positioning and consistent weld quality.
- PLC Touch Screen Control: Color touch screen allows easy adjustment of parameters for different profiles, supporting arbitrary angle welding for special-shaped windows.
