Brief Introduction of Four-head Seamless Welding Machine

Four-head Seamless Welding Machine is suitable for welding colour uPVC profiles. In the press welding process of uPVC profiles, this machine can clean the welding beadings on upper and bottom surface, and can control the size of welding seam (the seam size less than 0.2mm), making the corner good-looking and top grade. This uPVC seamless welding machine strengthen the hardness of welding through control system and pneumatic system, ensuring the welding hardness is the best in different environmental condition, and digital adjustment for related parameters is available. As cleaning the corner of window-door frame as noon as the welding is finished, there are not slots on the corner surfaces, which increase the interface of welding by 10%-20%. From the above mentioned, the welding strength of the uPVC window seamless welding machine is much better than common uPVC window welders.

Features of Four-head Seamless Welding Machine

• Meet the requirement of seamless welding (the seam size ≤0.2mm) for color and co-extrusion profiles.
• Pressure, temperature and welding time can be adjusted manually according to different uPVC profiles and external environmental condition
• Can weld the shape of ┏, ┏┓, ┏┳┓, ┳┳┳┳, ┏┳┳┓
• All welding heads can work independently and simultaneously
• Support arms for each welding head
• Welding movements are controlled by PLC, with high stability

The uPVC window welding machine is major and essential equipment for manufacturing uPVC windows and doors. The machine heats the end of uPVC profiles into molten state through heating plates, and then fabricates the uPVC profiles into a window frame unit or window sash unit by pressing. The movements of profile clamping, profile melting, and frame fabricating are controlled by a PLC, and all the movements are finished step by step automatically. Welding is the most important step for making uPVC windows and doors, and the welding quality (such as welding strength, welding-angle accuracy, window size accuracy) will affect the finished window quality directly. STONE Window Machinery guarantees the welding quality of the uPVC window welding machine through use of high quality heating plates and temperature controllers, high accuracy liner bearing motional pairs and other high quality machine components, and through our strict quality control system.
