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. Forming method: The plastic workpiece is melted and formed instantaneously by ultrasonic waves, and the metal or other materials of plastic can be made firm when the plastic is solidified.
  3. Riveting method: If you want 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 embrittlement, beautiful and strong.
  4. Spot welding method: Use small welding heads to weld two large plastic products at different points, or press the entire row of tooth-shaped welding heads directly on the two plastic workpieces, so as to achieve the effect of spot welding.

  5. 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 at the same time, and the embedding is completed after solidification.

6. Removal method: Utilizing the special design method of the welding head and the 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.
        The quality of products using ultrasonic welding machines is different from the stable quality after get off work. However, if everyone uses ultrasound after work, it is not work efficiency. Therefore, the countermeasure adopted at this time is to adopt an independent method for the air pressure source; require that products below 0.02m/m be equipped with a voltage stabilizing device on the ultrasonic machine; adjust the number of output stages and increase the power, but in general, the power of the ultrasonic welding machine is It is best to control the output between 2~4 stages. If you must work in 5~6 stages, the production time must be shortened as much as possible to avoid the loss of parts and vibrators.
