spot welding
A. There is no need to design the welding wire in advance to achieve the purpose of welding.
B. For relatively large workpieces, it is not easy to design welding lines for split-point welding to achieve the welding effect, which can be spot-welded at multiple points at the same time.
Cutting and sealing
Using the working principle of ultrasonic instantaneous vibration to cut chemical fiber fabrics, its advantages are smooth and clean without cracking or drawing. High-frequency and ultrasonic are two different concepts. High-frequency refers to electromagnetic waves with a frequency greater than 100Khz, and ultrasonic refers to sound waves with a frequency greater than 20 kHz. The welding principle and welding principle of high-frequency waves are also different from ultrasonic waves. High-frequency waves use high-frequency electromagnetic fields to make the internal molecules of materials violently collide with each other to generate high temperature to achieve the purpose of welding and welding. Ultrasound uses the principle of frictional heat generation to generate a lot of heat. To achieve the purpose of welding and welding.
welding method
The welding head vibrating with ultrasonic ultra-high frequency under moderate pressure makes the joint surfaces of the two plastics generate frictional heat and melt and join instantly. The welding strength is comparable to that of the main body. Suitable workpieces and reasonable interface design can be used to achieve watertightness. And airtight, and avoid the inconvenience caused by the use of auxiliary products, to achieve efficient and clean welding.
planting
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 to a certain depth. After completion, regardless of the tension and torque, it can be comparable to the traditional mold. Strength, can avoid the shortcomings of injection mold damage and slow injection.
molding
This method is similar to the riveting method. The concave welding head is pressed against the outer ring of the plastic product. After the welding head undergoes ultrasonic and 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 of electronics, speakers, and lens fixing in cosmetics.
riveting welding method
The ultrasonic super-high-frequency vibration welding head presses the protruding tip of the plastic product to instantly heat and melt into a rivet shape, so that materials of different materials are mechanically riveted together.
