What are the specific steps in the actual operation of PE hot-melt welding machine
Jan 21, 2019

The main function of PE hot-melt welding machine is to make hot-melt butt or socket for pe water supply pipe, gas pipe, fire pipe, green pipe, sewage pipe and so on. The specific operation steps are as follows: select the appropriate clamp fixture according to the welded pipe and fittings, and clamp the pipe to prepare for cutting.


Cutting the welded pipe section, the end face of the pipe fittings and the oxide layer to ensure that the butt end faces of the two pipes are smooth, smooth and free of impurities; the end faces of the two welded pipes should be completely centered, the smaller the wrong side, the better, the wrong side can not exceed 10% of the wall thickness, exceeding Will affect the quality of the docking. The docking temperature is generally between 210-230 ° C, and the heating time of the heating plate is different in winter and summer, and the melting length of the both ends is preferably 1-2 mm.


The heating plate of the PE hot-melt welding machine is removed, and the two hot-melt end faces are quickly adhered and pressurized. To ensure the welding quality, the switching cycle is as short as possible. Hot-melt butt joint is the key to welding. The docking process should always be carried out under the melt pressure. The width of the crimping should be 2-4mm.


During the cooling process of the PE hot melt process, the butt joint pressure should be kept constant, and the interface should be slowly cooled. The length of the cooling time is hard to touch the curled edge, and the heat is not felt. After the docking is completed, release the lining, remove the docking machine, and re-prepare the next interface for
