Brief Introduction of Four Head Welding Machine
Four-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.

Features of Four Head Welding Machine
 Can weld the shape of ┏, ┏┓, ┏┳┓, ┳┳┳┳, ╋╋╋╋
 All welding heads can work independently and simultaneously
 Support arms for each welding head
 Can weld any angle from 0°-180°with special locating plate
 Pressure, temperature and welding time can be adjusted manually according to different uPVC profiles and external environmental condition
 Welding movements are controlled by PLC, with high stability

The difference between HJ02-4500.4/4B and HJ02-4500.4/4A
HJ02-4500.4/4B uses high-precision linear bearing guide rails, and HJ02-4500.4/4A uses square guide rails.

The uPVC window welding machine is a major and essential equipment for manufacturing uPVC widnows 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 or door frame 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 Mahinery guarantees the welding quality of the uPVC window machine through adopting high quality heating plates and temprature controllers, high accuracy liner bearing motional pairs and other high quality machine components, and through our strick quality control system.
