With the continuous development of science and technology, the market division of labor is more and more clear, at the same time, in the technical level of welding machine, for different materials, there are corresponding ultrasonic welding machine equipment. For ultrasonic welding machine, the current popular market is mainly ultrasonic metal welding machine and ultrasonic plastic welding machine. 

1, ultrasonic metal welding machine ultrasonic metal welding machine is to use the energy generated by high frequency vibration, the same or different metal, under appropriate pressure through cold grinding and horizontal movement of the material surface molecular phase mutual infiltration, to achieve the purpose of welding. Ultrasonic metal welding is a highly efficient and reliable welding method. Its welding advantages are as follows: (1) welding materials are not molten and fragile metal characteristics. (2) Short welding time, without any flux, gas, solder. (3) Low requirements for welding metal surface, oxidation or electroplating can be welded. (4) After connection, the electrical conductivity is good, and the resistivity is very low or close to zero. (5) Welding without sparks, environmental protection and safety. 

2, ultrasonic plastic welding machine (1) high power ultrasonic welding machine welding plastic will not necessarily melt, to see the specific adjustment parameters. (2) Ultrasonic plastic welding machine generally can not be used in a few pieces of thickness between 2-3mm plastic welding, but does not rule out special conditions, such as structure/welding mode/ultrasonic machine power and so on have an impact. (3) When ultrasonic welding, if you want to clip the wire mesh between two pieces of plastic, you must add positioning method to make the wire mesh welding in the plastic will not move; (4) Hot melt plastic raw materials are more ideal for ultrasonic welding, the most common is ABS, PVC, PC acrylic and other materials. (5) The welding effect of the ultrasonic welding machine is related to the surface finish, otherwise there is no need to do the ultrasonic line on the plastic mold. "The ultrasonic wire is the ultrasonic waveguide fusion superpoint positioning device, usually in the form of contact line (or contact point) on the plastic mold. So in ultrasonic welding industry, the ultrasonic waveguide fusion superpoint locating device is called ultrasonic wire.
