What are the methods of ultrasonic plastic welding machine
The ultrasonic plastic welding machine is composed of pneumatic transmission system, control system, ultrasonic generator, transducer, tool head and mechanical device.
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 interface melting occurs. Under pressure, the two weldments can achieve beautiful, fast and firm welding effect.
2. Implantation (insertion) method: Nuts or other metals are to be inserted into the plastic workpiece. 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. 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 be brittle, beautiful and strong.
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, so as to achieve the effect of spot welding.
5. Forming method: The plastic workpiece is melted and formed instantaneously by ultrasonic waves. When the plastic solidifies, the plastic of metal or other materials can be firm.
