2. Welding and embedding method of 2.pvc: Embedding nuts or other metals into plastic workpieces. Firstly, ultrasonic waves are emitted to the metal. After high-speed vibration, the metal object is directly embedded in the molding plastic, and the plastic melts and solidifies to complete the embedding.
3. Welding riveting method of 3.pvc: If metal and plastic or two plastics with different properties are to be connected, ultrasonic riveting can be used to make the weldment not brittle, beautiful and firm.
4. Welding and spot welding of 4.pvc: weld two large plastic products with small welding heads, or directly press the whole row of toothed welding heads on two plastic workpieces to achieve the effect of spot welding.
5.pvc welding molding method: the plastic workpiece is instantly melted and molded by ultrasonic wave, which can make the plastic of metal or other materials firm when the plastic solidifies.
6. Welding removal method of 6.pvc: Using the special design method of welding head and base, the plastic workpiece is directly pressed on the plastic branch when it is just ejected, and the removal effect is achieved through ultrasonic conduction.
The working principle of pvc welding means that the quality of ultrasonic plastic welding depends on the amplitude of transducer welding head, applied pressure and welding time. Welding time and welding head pressure can be adjusted, and the amplitude is determined by transducer and horn. The interaction of these three quantities has a suitable value. When the energy exceeds an appropriate value, the melting amount of plastic is large, and the welded object is easy to deform. If the energy is small, it is not easy to weld firmly, and the external pressure should not be too large. As a typical representative of plastic welding machine, pvc welding machine has irreplaceable importance in industrial welding.
