Principle of equipment The plastic component to be fused is heated on the interface of the joint to be fused by a metal plate with a higher melting point than the plastic component material to make the interface of the plastic component melt. When the interface of plastic parts is melted, remove the hot metal plate and press the upper and lower two plastic parts so that the interface is fused. Characteristics of the equipment This machine has the characteristics of simple structure, convenient operation and high production efficiency. After welding, it can meet the requirements of water and air tightness. It is suitable for the welding of thermoplastic parts of various shapes, sizes and materials. It is a widely used, economical and practical, high production efficiency welding process. According to the process characteristics, production efficiency and different requirements of automation degree of all kinds of plastic parts, users can choose one machine multi-mode welding process, in a welding process, can complete the welding of several plastic parts at the same time, can also choose a high degree of automation of multi-table hot plate welding machine, for multi-station welding. It can also use special multi-head hot plate welding machine with multiple welding surfaces to achieve all the technological requirements of one welding. Scope of application Automobile industry: bumper, instrument panel, fuel tank, cylinder cover, front and rear combined light radiating grating, ventilation pipe, sun visor, etc. Other: steam iron, washing machine, vacuum cleaner, float ball, large pallet and other large irregular plastic parts that must be water tight, air tight and high strength. Used for welding large irregular plastics such as automobile lamps, balance rings of washing machines, accumulators, steam irons, automobile water tanks .
