High Power portable 20Khz Ultrasonic Spot Welding For Plastic label welding

Parameter

Common problems of traditional welding

1. High-temperature welding is easy to cause damage to the welding surface, and even deform the product in severe cases.
2. The welding equipment is large in size, not easy to handle by hand, and unable to complete complex procedures.
3. The welding mode is too single, the welding material is restricted, and the welding head cannot be replaced at will.
4. Adhesives and fluxes are used for welding, the welding pollution is serious, and the welding strength is not high.
5. Adhesives, buckles or other mechanical fixation are used when welding, which is inefficient and costly.

Ultrasonic spot welding technology

When ultrasonic waves act on the surface of thermoplastic plastics, high-frequency vibrations of tens of thousands of times per second are generated. The ultrasonic energy is transmitted to the welding area through the weldment, and local high temperature will be generated. Due to the poor thermal conductivity of plastics, heat is concentrated in the welding area, causing the surface of the plastic to melt rapidly, and after a certain pressure is applied, it is integrated.
Hand-held ultrasonic spot welding machine can be used for welding, riveting, spot welding of films, fabrics, and thermoplastic products, as well as inlay and edge pressing processes between metal parts and plastic parts

Advantages of ultrasonic spot welding

High stability: The digital electric box automatically tracks the resonant frequency and adjusts the output frequency to match the handheld device. Once a fault is found, it stops working and gives an alarm. Most of the ultrasonic welding can be completed within 0.1-0.5 seconds.
Energy-saving and environmental protection: The welding surface is not damaged or deformed, without scratches and adhesive residues, avoiding the use of a large number of fixtures, fluxes, and adhesives, reducing labor and cost.
Reliable quality: Ultrasonic welding is solidified and formed, and the molecules are recombined to form a strong molecular chain. The strength of the weld can be close to the strength of the raw material. .
Simple operation: Ultrasonic welding is very easy to realize automation. As long as the welding parameters are set, the welding can be carried out without preheating or cleaning.
Wide range of applications: Hand-held ultrasonic spot welding machines can be used for welding, riveting, spot welding of films, fabrics, and thermoplastic products, as well as inlay and edge pressing processes between metal and plastic parts.
