The basic principle of ultrasonic welding is to convert high-frequency electric energy into high-frequency vibration mechanical energy. This reciprocating vibration is transmitted to thermoplastic or metal, and friction and heat are generated at the interface of plastic and plastic, plastic and metal, or metal and metal. In ultrasonic welding, friction generates heat to fuse two material surfaces ...

Thanks to the development of the digital age and the increasing demand for high-quality electronic products, metal connection technology has achieved long-term development-from traditional bolts, nails and even adhesive connections to today's ultrasonic metal welding. What is ultrasonic metal welding? Ultrasonic metal welding is a kind of "cold welding", which does not melt metal. It uses ultrason...

With the rapid development of industrial production, plastics are widely used in various fields of the national economy and people's lives with their advantages of light weight, high specific strength, corrosion resistance, and easy processing. In engineering, plastic welding rods require that the composition of the material is the same as the composition of the material to be welded, but the stre...

There are two types of spot welding of ultrasonic welding machine: surface spot welding and single-sided spot welding. The welding characteristics of the two categories are also different. For example, in double-sided spot welding, the electrodes are fed from both sides of the workpiece to the welding place. The conductive plate of the welding area is used as the lower electrode, which can elimina...

We need to clarify that the welding method of the ultrasonic plastic welding machine is to conduct sound waves, which are converted into heat energy through vibration and friction to achieve the purpose of welding. In this way, the degree of anastomosis of the ultrasonic mold, the height, depth, and material organization of the product section must not be able to withstand the same pressure value....
