How To Adjust The Welding Strength Of Ultrasonic Plastic Welding Machine?

Now many people will use ultrasonic plastic welding machine to process plastic workpieces. After processing, the factory will also conduct quality sampling inspection on products. According to different product types and requirements, the required detection methods are also different, usually including air tightness detection, impact resistance detection, DC high voltage detection and pressure detection. If the product quality is found to be unqualified, the welding strength of the ultrasonic plastic welding machine will be adjusted to improve the bright connection quality.

Ultrasonic plastic welding machine has many parameters, including frequency and power. Adjusting the size of parameters can adjust the welding strength. There is a tuning knob on the ultrasonic welding machine, which is a key adjustment button on the equipment. By adjusting it, the frequency of the high-voltage electric signal sent by the ultrasonic generator can be consistent with the mechanical resonance frequency of the transducer. The method of operating the tuning knob is also relatively simple. Just touch the test switch and rotate the button left and right. Secondly, ultrasonic plastic welding machine can convert ultrasonic energy into heat energy, improve the wettability between welding areas, enhance the diffusion ability between molecular chains, and form a strong combination through intermolecular diffusion and chain entanglement, so as to achieve the effect of controlling welding strength. In addition, the welding strength can also be adjusted by the amplitude, pressure holding time and welding time of the ultrasonic plastic welding machine.

The adjustment of ultrasonic plastic welding machine has high requirements for operators. If the operator does not have sufficient experience, it is difficult to accurately adjust the equipment. With the continuous development of industrial automation, the factory has higher and higher requirements for ultrasonic welding. This difficult adjustment problem needs to be solved urgently, otherwise the welding machine will be replaced by other equipment. At present, many ultrasonic plastic welding machine manufacturers in China are committed to improving the automation level of the equipment, trying to turn it into a fool machine and reduce the burden of operators.
