1. Welding method: The welding head vibrating with ultrasonic ultra-high frequency under moderate pressure makes the joint surface of the two plastics generate frictional heat and instantaneously melt and join. The welding strength is comparable to that of the main body. Suitable workpieces and reasonable interfaces are used. The design can be watertight and airtight, and avoid the inconvenience caused by the use of auxiliary products, and realize efficient and clean welding.
2. Riveting welding method: press the welding head of ultrasonic ultra-high frequency vibration to press the protruding tip of the plastic product to make it instantly heat and melt into a rivet shape, so that the materials of different materials are mechanically riveted together.
3. Implantation: With the propagation of the welding head and appropriate pressure, metal parts (such as nuts, screws, etc.) are instantly squeezed into the reserved plastic holes, and fixed at a certain depth. After completion, the tension and torque can be comparable The strength of the traditional in-mold molding can avoid the shortcomings of damage to the injection mold and slow injection.
4. Forming: This method is similar to the riveting welding method. The concave welding head is pressed against the outer ring of the plastic product. After the welding head undergoes ultrasonic ultra-high frequency vibration, the plastic is melted into shape and covered with the metal object to fix it, and The appearance is smooth and beautiful. This method is mostly used in the fixing and forming of electric speakers, horns, and fixing of cosmetic lenses.
5. Spot welding: A. There is no need to design the welding wire in advance to weld the two pieces of plastic to achieve the purpose of welding. B. For relatively large workpieces, it is not easy to design the welding line to perform split-point welding to achieve the welding effect, which can be spot-welded at multiple points at the same time.
6. Cutting and sealing: Using the working principle of ultrasonic vibration to cut chemical fiber fabrics, its advantages are smooth and clean without cracking or drawing.
