1. Welding method: Under moderate pressure, the welding head vibrating with ultrasonic wave and high frequency causes frictional heat of the two plastic joints and instantaneous fusion welding. The welding strength is comparable to that of the body. Appropriate workpiece and reasonable interface are adopted. Designed to achieve watertightness and airtightness, and eliminate the inconvenience caused by the use of auxiliary products, and achieve efficient and clean welding.
Second, riveting welding method: The ultrasonic welding head with high frequency vibration is pressed against the protruding tip of the plastic product, so that it instantly heats and melts into a rivet shape, and the materials of different materials are mechanically riveted together.
3. Embedding: With the help of the welding head and proper pressure, the metal parts (such as nuts, screws, etc.) are squeezed into the reserved plastic holes in an instant, fixed at a certain depth, regardless of the pulling force and torque after completion The strength of the molding in the traditional mold can avoid the disadvantages of damage to the injection mold and slow injection.
4. Forming: This method is similar to the riveting and welding method. The concave welding head is pressed against the outer ring of the plastic product. After the welding head produces ultrasonic ultra-high frequency vibration, the plastic is melted and formed to cover the metal object to fix it, and The appearance is smooth and beautiful. This method is mostly used in the fixing of electronics and speakers, and the fixing of lenses in cosmetics.
5. Spot welding: A. Weld the two pieces of plastic in a point-by-point manner without pre-designing the welding wire to achieve the purpose of welding. B. For relatively large workpieces, it is not easy to design the welding line to carry out spot welding, and to achieve the welding effect, it can spot weld multiple points at the same time. Sixth, cutting and sealing: the use of ultrasonic ultrasonic vibration principle to cut chemical fiber fabrics, its advantages are smooth and clean without cracking or drawing.
