Ultrasonic welding is a fast, clean and effective assembly process for processing thermoplastic parts and some synthetic components. At present, it is used in the bonding between plastic products, plastic products and metal accessories and other non-plastic materials, it replaces the solvent adhesive, mechanical fixation and other bonding process, is an advanced assembly technology. At the same time can be the same or different metal, under appropriate pressure through cold grinding and horizontal movement of the metal surface molecules permeate each other, to achieve the purpose of welding. Ultrasonic welding not only has the function of connection and assembly but also has the sealing effect of moistureproof and waterproof.

Advantages of ultrasonic welding technology:
1, energy saving, only a small power can achieve welding
2, do not need to be equipped with smoke dissipation ventilation device
3, welding without welding accessories, low cost, high efficiency
4, no leakage, no leakage, air tight welding, high quality
5, easy to achieve automatic production of ultrasonic plastic welding technology advantages:
1. Fast and accurate -- most ultrasonic welding can be completed in 0.1-0.5 seconds
2, stable quality -- mechanized production, stable and reliable product quality
3, economic benefits - free of a large number of fixtures, adhesives, reduce labor, reduce costs
4, beautiful and clean - the surface is well formed, no damage, no deformation, no scratches and adhesive residue marks
5, the process is simple -- no need to preheat, no need to clean and other processes
6, convenient operation -- as long as the welding parameters are set, the operation is very convenient
7, high strength, good air tightness -- the weld composition is the same as the base material, high strength, good air tightness, water tight, air tight
8, can realize automatic welding -- 15K ultrasonic plastic welding machine is very easy to achieve automation
Advantages of ultrasonic metal welding technology:
1, high reliability: through time, energy, power and high limit monitoring, to ensure excellent process control
2, cost saving: avoid consumables such as solder, flux, bending and brass materials, making ultrasonic welding the most cost-effective process
3, low energy consumption: the energy required by ultrasonic welding is less than resistance welding
4, tool life: ultrasonic tools are processed with high-quality tool steel, with excellent wear resistance, easy installation, high welding accuracy
5, high efficiency and automation: typical welding speed is not more than 0.5 seconds, small size, less maintenance workload, strong adaptability, so that ultrasonic equipment becomes the first choice for automatic assembly line
6, low working temperature: because ultrasonic welding does not produce a lot of heat, so it will not make the metal workpiece annealing, will not make the plastic shell melting, also do not need cooling water

7, in addition to insulation: in most cases, the high-frequency friction of ultrasonic welding makes people do not need to peel the insulation skin of enamelled wire or clean the workpiece surface in advance.
