   The principle of ultrasonic plastic welding is to generate 20KHz (or 15KHz) high-voltage and high-frequency signals from the generator. Through the energy conversion system, the signal is converted into high-frequency mechanical vibration, which is applied to the workpiece of the plastic workpiece and passes through the surface of the workpiece and between the molecules. Friction causes the temperature transmitted to the interface to rise. When the temperature reaches the melting point of the workpiece itself, the workpiece interface is rapidly melted, and then the air gap between the interfaces is filled. When the vibration stops, the workpiece is simultaneously cooled and shaped under a certain pressure. A perfect weld is achieved.


Ultrasonic welding machines can be divided into automatic welding machines, semi-automatic ultrasonic welding machines, and manual welding machines according to the level of automation。 。 According to the frequency cable can be divided into: 15K, 20K, 28K, 30K, 35K, 40K and other models。
   15k ultrasonic welding machine power can be divided into 2600W 3200W 4200W. Suitable for welding saddle large, difficult to weld, more complex plastic 20khz ultrasonic welding machine for small size, simple structure of plastic parts, Ming 20K digital intelligent ultrasonic welding The machine is a high-tech welding equipment jointly developed by the German ultrasonic expert team. It adopts international advanced design concept, high-quality imported electronic components, digital circuit and program software control technology, with automatic frequency scanning and diversified welding mode. The functions of inspection, fault automatic detection and protection, power cable adjustment man-machine dialogue, open communication interface, software upgrade, etc. are convenient and reliable.
   [Laser welding machine] Ultrasonic welding machine type
28K.30K ultrasonic plastic welding machine is often called ultrasonic spot welding machine portable ultrasonic welding machine handheld ultrasonic welding machine has the advantages of light body, easy to carry, easy to move and so on. Hand-held ultrasonic welding machine can be divided into: ultrasonic observation Spot welding machine, ultrasonic metal welding machine, polymer battery positive spot welding machine, lithium battery negative spot welding machine, aluminum to nickel spot welding machine, amorphous silicon spot welding machine, etc. Suitable for spot welding, pressure welding, joining, boring, Process of boundary flower, dot marking, sealing, screw embedding, decal welding, etc.
   35K40K ultrasonic welding machine is used for small and high precision electronic products such as: flash card, U disk SD card, SM card, comfort pacifier, spot welding, embossing and other electronic products welding.
   Laser welding machine ultrasonic plastic welding machine is used for welding, joining and implanting ABS, PE, PC, PS, PVC, PP, SAN, PA, acrylic, nylon, ABS and PC composite materials, as long as the welding head With changes, it can be used in a variety of applications, widely used in electronics, electrical appliances, automotive parts, plastic toys, stationery, daily necessities, handicrafts, cosmetics and other industries。
