Brief Introduction of Vertical Four Corner Welding Machine
Vertical four-corner welding machine is the special machine for the welding of uPVC doors & windows, and an ideal equipment for mass production of uPVC windows and doors. The four welding heads can finish the welding of rectangle window frames or sashes in one operation, featuring high efficiency.
Compared with other uPVC welding machines, significantly, the four-corner welding machine improves the welding strength, welding accuracy and durability of uPVC windows and doors through window-frame parallel welding and synchronous profile-clamping technology, PLC programmer control, and high-accuracy liner bearing motional pairs. Additionally, good-performance and long-life pneumatic components, imported industrial PLC in control system, and high-strength machine construction, guarantee the service life of the uPVC window welding machine. This machine is easy to operate with user-friendly human-machine interface, and easy to maintain with pneumatic driving system and motional pairs of oil-free lubrication bearings.

The uPVC window welding machine is a major and essential equipment for manufacturing uPVC windows and doors. The machine heat the end of cutted uPVC profiles into molten state through heating plates, and then fabricate 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 one by one automatically. Welding is the most important step for making PVC windows and doors, and the welding quality (such as welding strength, welding-angle accuracy, window size accuracy) will affact the finished window quality directly. STONE Window Machinery guarantees the welding quality of the uPVC window machine through adopting 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.
