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.
