As an important component of the cooling circuit of the water-cooled engine, the automobile water bottle keeps the heat of the engine, absorbs the heat of the cylinder block and prevents the engine from overheating by circulating the coolant in the engine water channel. It is a water holding device with large area and complex manufacturing process. Because the material of the kettle is thermoplastic material, the most convenient way in the production process is to use plastic welding equipment for welding production.
The hot plate machine is a kind of mechanical equipment which uses the principle of electrothermal melting and perfect mechanical device to complete the welding operation.
During welding, the heating plate is placed between two plastic parts. When the workpiece clings to the heating plate, the plastic begins to melt. After heating for a period of time, the plastic on the surface of the workpiece will reach a certain degree of melting. At this time, the workpiece will be separated from both sides, the heating plate will be removed, and then the two workpieces will be combined. When the welding time and depth reach a certain degree, the whole welding process will be completed. It is suitable for welding large and complex plastic parts with special welding requirements. As a kind of plastic product with welding process, automobile water bottle is just suitable for welding production with hot plate machine.
