Ultrasonic spot welding technology
When the ultrasonic wave acts on the surface of thermoplastic, it will produce tens of thousands of times of high-frequency vibration per second. The ultrasonic energy is transferred to the welding area through the weldment, and local high temperature will be generated. Because of the poor thermal conductivity of plastic, heat gathered in the welding area, resulting in rapid melting of the plastic surface, with a certain pressure, so that it is integrated.The handheld ultrasonic spot welding machine can be used for film, cloth, thermoplastic products welding, riveting, spot welding and metal and plastic parts inlaying and holding process.

Ultrasonic spot welding machine application scope:
1. Plastic toys, water guns, aquatic game machines, children's dolls, plastic gifts, etc.
2. Electronic products: recording, cassette box and core wheel, disk shell, cell phone panel and rectifier transformer, switch socket, remote control, electronic mosquito bat, imitation bottle cap, etc.
3. Home appliances: electronic clock, hairdryer, steam iron water tank, electric kettle, computer, etc.
4. Stationery and daily necessities: writing case, aquarium ruler, folder slot and shell, pen holder, cosmetics box shell, toothpaste tube seal, cosmetic mirror, vacuum cup, lighter, seasoning bottle and other sealed containers.
5, automobile, motorcycle: battery, front corner light, rear car light, instrument, reflector, etc.
6, sports industry applications: table tennis, table tennis, badminton racket, tennis racket, golf clubs, billiard tables, treadmill roller rope skipping handle Treadmills, running machine accessories, vaulting box, gymnastics MATS boxing sandbags, sanda, boxing gloves, protective devices, path ShiYiPai, X exhibition shelf and other sports equipment widely used in ultrasonic plastic welding machine for plastic spot welding, etc.
7. Ultrasonic washing machine for metal mechanical parts, bearings, pneumatic components, electronic components, optical components, medical components, gold and silver ornaments and parts before electroplating. Power from 100W to 5000W, but also according to user needs to design and manufacture tank type, immersion type, heating type and high density, low frequency and other non-standard special models.
8. Ultrasonic lace dissolving and breaking machine, ultrasonic cotton tuck machine, ultrasonic lace machine and ultrasonic mask retenting machine are a new production process in the textile and garment industry, which can help the industry to improve the product grade, improve productivity and reduce the working intensity.

Advantages of ultrasonic spot welding machine:
1, high stability: the digital electrical box automatically tracks the resonant frequency, adjust the output frequency to match the handheld equipment, once the fault is found, stop working and alarm, most of the ultrasonic welding can be completed within 0.1-0.5 seconds.
2, energy saving and environmental protection: the welding surface is not damaged or deformed, no scratches and cement residue marks, free of a large number of fixtures, flux, cement, reduce labor and reduce costs.
3, reliable quality: ultrasonic welding solidification molding, molecular recombination, forming a strong molecular chain, weld strength can be close to the strength of raw materials, good air tightness, water leakage, air permeability.
4, simple operation: ultrasonic welding is very easy to achieve automation, as long as the welding parameters are set, can be welded, do not need to preheat, do not need to clean and other processes.
5, a wide range of applications: handheld ultrasonic spot welding machine can be used for film, cloth, thermoplastic products welding, riveting, spot welding and metal and plastic parts of the inlaying and blank holding process.
