Ultrasonic welding of plastic boxes: Ultrasonic plastic welding is a new technology, which integrates microcomputer, ultrasonic, electronic and mechanical technology. It overcomes many shortcomings of plastic bonding and heat-sealing processes that have been used for many years. It has considerable economic benefits and a wide range of Application areas. With the development of plastic material technology, various plastic products in the plastic industry are widely used in aviation, automobiles, shipbuilding, electronics, toys and other fields. Due to the limitations of plastic processing technology and other factors, quite a few plastic products with complex shapes cannot be molded at one time, and plastic bonding and heat sealing processes are required. This process is not only low in efficiency, unsightly welding, low bonding fastness, but also environmental pollution and other problems. Ultrasonic plastic welding is a frequency modulation current generated by an ultrasonic generator, which is converted into high-frequency vibration mechanical energy by a piezoelectric transducer, and is transmitted to the welding head through an horn for welding of plastic parts.

Due to the different sizes and shapes of welding objects, the welding heads are designed to be round, tapered, and rectangular. The high-frequency mechanical vibration on the welding head is transmitted to the welding surface. Under the action of high-frequency vibration, the high temperature instantly makes the welding surface form a molten layer, which is fused and solidified under the controllable pressure of the welding machine, so as to realize the firmness of the two plastic parts. Combine. 

Ultrasonic plastic box welding: The application of ultrasonic plastic pressure welding technology. Plastic pressure welding is specially used for welding two plastic workpieces, specifically the welding of plastic shells and plastic boxes. Specific applications: laptop batteries, computer chargers, mobile phone chargers, battery car chargers, lithium battery casings, mobile phone batteries, plastic stationery, plastic toys, power adapters, car speakers, electric meter casings, three-phase electric meter casings, water meter casings, Cosmetic boxes, solar junction boxes, generator junction boxes, motorcycle battery covers, etc. Mostly, ABS plastic, PP plastic, PC plastic, AS plastic, PC plastic, PS plastic, PE plastic and other plastic material shells are connected and welded to the box.
