1. Welding method Ultrasonic vibration transmits the ultrasonic wave to the weldment along with the welding head. Due to the large acoustic resistance at the two weldments, local high temperature is generated and the interface of the weldment is melted. Under certain pressure, the two weldments can achieve beautiful, fast and firm welding effect.

2. Embedding method Nuts or other metals are to be inserted into plastic workpieces. First, the ultrasonic wave is transmitted to the metal, and the metal object is directly embedded in the molded plastic through high-speed vibration, and the plastic is melted, and the embedding is completed after solidification.

3. Riveting method To join metal and plastic or two pieces of plastic with different properties, ultrasonic riveting can be used to make the weldment not easy to embrittlement, beautiful and firm.

4. Spot welding method Use small welding heads to weld two large plastic products at points, or a whole row of tooth-shaped welding heads are directly pressed on two plastic workpieces to achieve the effect of spot welding.

5. Molding method Utilize ultrasonic waves to instantaneously melt and shape the plastic workpiece. When the plastic solidifies, it can make the metal or plastic of other materials firm.

6. Removal method Utilizing the special design method of the welding head and base, when the plastic workpiece is just shot, it is directly pressed on the plastic branch, and the removal effect is achieved through ultrasonic transmission.
