Ultrasonic Riveting Handgun/Ultrasonic Spot Welding Gun
The principle of ultrasonic welding is through the ultrasonic generator to convert high-frequency electrical energy into higher frequency mechanical movement, then mechanical movement through a set of amplitude can be changed to the transmission device to the welding head.
The welding head transmits the received vibration energy to the joint portion of the workpiece to be welded, in which the vibration energy is converted into heat energy by friction and the plastic is melted.
Ultrasonic not only can be used to weld hard thermoplastics, but also can process fabrics and films.

Ultrasonic automotive plastics as the condition of ultrasonic welding, the most important is the time to apply welding energy (vibration, welding time) length and pressure, of course, other conditions are also very important. Welding temperature, ultrasonic welding material viscosity, flow temperature. Otherwise the material will not melt.
With the amplitude, the higher the amplitude, the higher the temperature rise. The pressure is applied to the molded article using a cylindrical gaze. General compressed air pressure is 0.1-0.3MPa (pressure gauge), sometimes higher. But if the use of high pressure, it will hinder the cylindrical vibration.
The welding time varies depending on the material and the shape of the product. The welding time of some molded articles is only 0.2 seconds.
Over time will cause excessive welding and produce a lot of flash and bubble, resulting in poor airtight, must pay attention. Cooling (holding) time For crystalline plastic, if the temperature below the melting point, the connection will be solidified, usually the pressure time is maintained between 0.1-0.2 seconds. AMMA plastic).
Ultrasonic riveting: the nature of metal and plastic or two different plastic bonding together, can make use of ultrasonic riveting machine, so that the weldment hard brittle, beautiful, strong.
Ultrasonic welding: the use of ultrasound machine small welding head, the two pieces of plastic products into multi-point welding, or welding the first row of teeth on a direct pressure on the two plastic work piece, so as to achieve the effect of ultrasonic welding.
Ultrasonic implants: the nut screws or other metal into plastic work piece. Ultrasonic energy through the ultrasound machine will be transmitted to the metal. The high-speed vibration and heat, the pressure in the ultrasound machine to make metal objects embedded directly into the plastic inside.
Plastic contact surface resulting in rapid melting, coupled with stress, it blend and coagulation, so that to achieve the purpose of ultrasonic welding.
