Brief Introduction of Three Head Welding Machine

Three-head Welding Machine for PVC Door & Window is a special machine for processing uPVC doors and windows. The machine guarantees the welding strength, welding accuracy and durability of uPVC windows and doors through PLC programmer control, pneumatic driving system, and high-accuracy liner bearing motional pairs. 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, easy to operate. 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. The machine is one of essential uPVC window manufacturing machines.

The uPVC window welding machine is major and essential equipment for manufacturing uPVC windows and doors. The machine heats the end of cutted 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 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 affect 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.
