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 a certain pressure, the two weldments can achieve a beautiful, fast and firm welding effect.
2. Implantation (insertion) 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. At the same time, the plastic is melted, and the embedding is completed after solidification.
3. Forming method: The plastic workpiece is melted and formed instantaneously by ultrasonic waves, and when the plastic is solidified, the plastic of metal or other materials can be made firm.
4. Removal method: Using the special design of the welding head and base, when the plastic workpiece is just shot, it is directly pressed on the branch of the plastic, and the removal effect is achieved through ultrasonic transmission.
5. Riveting method: To join metal and plastic or two pieces of plastic with different properties, ultrasonic riveting method can be used to make the weldment not easy to be brittle, beautiful and strong.
6. 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.
