The working principle of ultrasonic welding machine is fast, economical, efficient and environmentally friendly, especially in the operation of thermoplastic parts and the synthesis of other workpieces. At present, the principle of ultrasonic welding machine is widely used in the synthesis of plastic products and plastic materials, metal parts and metal materials, There are also some other materials and industrial and technological operations.

It completely surpasses the old solvent fusion operation, flux welding, adhesive bonding and other welding aid fusion synthesis technology, not only has the advantage of saving, because of the advanced ultrasonic principle technology, no operation pollution, so it is very environmental protection, the perfect welding operation effect is comparable to the material itself, the welding quality is solid, the welding operation appearance is beautiful, The sealing effect of welding operation can not be compared with the old technology.

In recent years, with the rapid development of plastic industry, all kinds of plastic products have been widely used in aviation, automobile, shipbuilding, electronics, toys and other industrial fields, and achieved remarkable results and economic benefits. However, due to the limitation of injection molding process and other factors, a considerable number of plastic products with complex shape can not be molded at one time, which requires bonding. However, the plastic bonding and heat bonding process which has been used for many years is quite old. This old technology not only has low efficiency, but also makes operators deal with pungent adhesive or high temperature heat source all day, which causes a series of thorny problems such as environmental pollution and labor protection; In addition, in the bonding process of plastic parts, there is the phenomenon of adhesive sagging at the joint, resulting in the loss of smoothness and beauty of the finished product; Especially serious is. This method of bonding fastness is not high, poor sealing. Should not be bonded to pressure vessels. Obviously, this technology can not meet the needs of the development of plastic industry, so a new plastic processing equipment - ultrasonic plastic welding machine came into being. When the ultrasonic welding machine is used to weld plastic parts, there is no need to add any adhesive or soldering agent, and no need to use heat source. It has the advantages of simple operation, fast welding speed and good quality.
