WHJ4-150×4500 Four Heads Seamless Welding Machine

WHJ4-120*4500 is a four heads seamless welding machine dedicated to PVC door and window manufacturing, with 1-4 heads optional to flexibly adapt to different production scales and processing needs. Applicable to white and colored PVC profiles, it can weld 4 corners at a time, supporting 90° and V-shaped corners as well as multiple welding shapes. It is widely used in professional PVC door and window factories and large-scale PVC profile processing workshops, meeting the high-efficiency, high-quality seamless welding needs of batch production of PVC window frames. It ensures slag-free, smooth welding joints, improving product aesthetics and sealing performance, and is an essential equipment for high-standard PVC door and window production.

1. Flexible Head Selection: 1-4 heads optional, which can be adjusted according to production volume and processing requirements, adapting to both small-batch customization and large-scale batch production, improving equipment utilization.

2. High-Efficiency Batch Welding: Standard four heads can weld 4 corners at one time, matched with automated welding process, greatly shortening the welding cycle and improving production efficiency.

3. Seamless High-Quality Welding: Adopts seamless welding technology, no slag left on the upper and lower corners after welding, ensuring neat, smooth welding joints, enhancing the aesthetics and sealing performance of PVC doors and windows.

4. Versatile & Convenient Operation: Supports 90°/V-shaped corners and multiple welding shapes, meeting diverse PVC window frame structure needs; touch screen enables easy adjustment of melting and welding time, and movable right three heads can be locked manually or pneumatically for stable operation.

5. Strong Profile Adaptability: Applicable to white and colored PVC profiles, with several matching backing plates for different profile types, avoiding profile deformation during welding and ensuring consistent processing quality.
