Advantages of ultrasonic welding applied to plastic shell welding

Apr 24, 2022

With the development of plastic material technology, ultrasonic welding machine is widely used in medical, electronics, electrical appliances, consumables, auto parts, non-woven fabrics, office supplies and toys industries of all kinds of plastic products. Due to the influence of plastic bonding process of too many factors, there are many complex plastic products can not be formed at a time, but also need plastic bonding and thermal bonding process. However, the efficiency of the process itself is low, some of which also need to add adhesive, resulting in ugly welding products, low bonding fastness, but also easy to produce environmental pollution and other problems. But the use of ultrasonic welding machine will not appear this problem, ultrasonic welding can not only improve production efficiency, low cost, but also improve product quality and production safety.


Principle of ultrasonic plastic box welding machine:

The ultrasonic energy is transmitted to the welding zone through the upper weldment. The two welded interfaces generate high speed friction heat and local temperature rises. And because of the poor thermal conductivity of plastic, can not timely heat dissipation, gathered in the welding area, resulting in the rapid melting of the two plastic contact surface, under a certain pressure, so that the fusion into one. When the plastic box welding machine ultrasonic stopped, let the pressure continue, a little pressure holding time, so that it solidifies into shape.


According to welding requirements, ultrasonic welding machine can choose semi-automatic or automatic mode, welding temperature, heating time, cooling time, heating depth, welding depth pressure, conversion time and other parameters are adjustable.


Plastic box welding machine is suitable for: electricity meter box welding, water meter box welding, power adapter welding, U disk welding, telephone handset welding, electric mosquito clap welding, electric toothbrush handle welding and so on.
