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, 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.

The handheld ultrasonic spot welding machine can be used for the welding, riveting, spot welding of films, fabrics, and thermoplastic products, as well as the inlay and edge pressing process between metal parts and plastic parts.

Most people familiar with the ultrasonic industry know that ultrasonic equipment will produce screams and particularly harsh ears during the working process, causing certain harm to the human body. How to adjust this phenomenon, and the solutions are 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 for the fine adjustment of the upper and lower height of the ultrasonic spot welding machine head.

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.
