company news about How to adjust the sound produced by the ultrasonic spot welding machine

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, which will generate local high temperature. 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, 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 and plastic parts.
Most people who are familiar with the ultrasonic industry know that ultrasonic equipment will produce screams and particularly harsh ears during the work process, causing certain harm to the human body. How to adjust this phenomenon, and now propose solutions as follows:

1. Adjust the air pressure of the ultrasonic spot welding machine to the appropriate air pressure (2-5kg/cm2) according to the products to be welded.
2. There is a special fine-tuning screw to adjust the height of the ultrasonic spot welding machine head up and down.
3. The ultrasonic spot welding machine must adjust the appropriate welding parameters when welding the product: the setting of the three time parameters of delay, welding, and curing. Pay attention to the adjustment of the delay time when the ultrasonic welding machine screams.
Friendly reminder: It is best to bring earplugs and other products that protect your ears during work.
