Introduction to Ultrasonic Welding Technology

Ultrasonic plastic welding machine is suitable for welding, riveting, spot welding of thermoplastic products, as well as inlaying and edge pressing processes between metal and plastic parts. It eliminates the outdated process of using chemical organic melting point agents for bonding, and has the characteristics of low energy consumption, high efficiency, no deformation, no pollution, firm welding, and easy operation. The product adopts advanced circuits, program control, pneumatic transmission, automatic overcurrent protection, and safety operation protection circuits. The circuit adopts a circuit board insertion structure, which is convenient for maintenance and replacement. The new 15KHz ultrasonic plastic welding machine with electronic delay welding device is also designed. It has advantages in welding softer PE and PP materials, as well as plastic welding parts with super large diameter and length. It can meet the needs of various products and contribute to improving production efficiency and product grade for users.

Scope of use of ultrasonic plastic welding machine:

1. Cars and motorcycles: batteries, front corner lights, rear lights, instruments, reflectors, etc.

2. Stationery daily necessities: stationery box, aquarium ruler, folder seam and shell, pen holder, cosmetic box shell, toothpaste tube sealing tail

Sealed containers such as makeup mirrors, thermos cups, lighters, and seasoning bottles.

3. Household appliances: electronic clock, electric drum blower, steam iron water tank, electric kettle fan, computer, etc. 4. Electronic products: recording, cassette box and core wheel, disk casing, mobile phone battery board and rectifier transformer, switch socket

Remote control, electronic mosquito swatter, counterfeit bottle cap, etc.

5. Plastic toys, water guns, aquarium game consoles, children's dolls, plastic gifts, etc.

The use of ultrasonic welding technology in the plastic industry has become increasingly common around the world. Due to the application of this technology, it can replace the fluxes, adhesives, fasteners, or other mechanical fixation methods required in previous production, thereby improving production efficiency and reducing costs. The principle of ultrasonic welding is that an ultrasonic generator generates a high voltage and high frequency signal of 20KHz (or 15KHz), which is converted into high-frequency mechanical vibration through an energy conversion system. The signal is applied to a plastic product workpiece, and the temperature from the transmission point to the interface is increased through friction between the surface and internal molecules of the workpiece. When the temperature reaches the melting point of the workpiece itself, the interface of the workpiece quickly melts, and then fills the gaps between the interfaces; When the vibration stops and the workpiece is cooled and shaped under a certain pressure, welding is achieved. 1. Ultrasonic welding technology is also applicable to various industries such as ultrasonic handheld plastic welding machines, ultrasonic plastic hose sealing machines, ultrasonic punching machines, ultrasonic frequency correction generators, plastic inner folding machines for plastic stationery, and organ clip forming machines. 2. Ultrasonic welding technology is suitable for ultrasonic lace breaking machines and ultrasonic pleating machines in the textile, clothing, and craft accessories industries. It is a new production process in this industry that helps to improve product quality. 3. Ultrasonic welding technology is applicable to ultrasonic washing machines for electroplating pretreatment of hardware mechanical parts, bearings, pneumatic components, electronic devices, optical devices, medical devices, gold and silver jewelry, and parts. Power ranges from 100W to 5000W, and non-standard special models such as slot, immersion, heating, high-density, and low-frequency can be designed and manufactured according to user needs. 4. Ultrasonic welding technology is suitable for ultrasonic plastic welding machines, plastic hot plate welding machines, and high-frequency plastic welding machines in industries such as plastic toys, electronics, household appliances, daily plastic products, plastic stationery, and automotive parts. In addition to the 20KHZ universal series, the ultrasonic plastic welding machine also produces the 15KHz series specifically designed for soft materials such as PP and PE, as well as for workpieces with ultra large diameters and ultra long widths. The power range from 1000W to 4200W, which can meet the requirements of different users. No need to use needles or thread, eliminating the hassle of changing needles and thread; The product is aesthetically pleasing and has a more three-dimensional feel, catering to the trend of the times; You can choose to change the pattern as needed; High production intensity and high production efficiency.
