Ultrasonic cleaning machines are efficient and environmentally friendly cleaning devices that utilize the cavitation effect generated by ultrasound in liquids to clean the surfaces of hardware and plastic parts. They mainly consist of an ultrasonic generator, a transducer, and a cleaning tank, capable of cleaning every gap and corner of complex workpieces, achieving a dead-angle-free cleaning effect.

Ultrasonic cleaning machines are widely used in various industries such as surface coating treatment, machinery, electronics, medical, semiconductor, watch and jewelry, optics, textile printing and dyeing, and more. For example, in the machinery industry, they can be used to remove contaminants like cutting oil, abrasive particles, iron chips, and dust; in the electronics industry, they can clean dust and oil stains on the surfaces of electronic components.
Main Features
1. Dead-angle-free cleaning: Ultrasonic cleaning equipment can accommodate batch cleaning of multiple workpieces and clean every gap and corner of complex workpieces, achieving a dead-angle-free cleaning effect.
2. Reduced labor intensity: Ultrasound provides fast and efficient cleaning, reducing workers' labor intensity and creating a clean and orderly cleaning environment.
3. Environmentally friendly cleaning: Ultrasonic cleaning machines are equipped with an efficient circulation and filtration system. Used cleaning solvents can be filtered through the system for reuse, thereby saving water resources and cleaning solvents, reducing cleaning costs for enterprises, and enhancing environmental sustainability.
Ultrasonic frequency: For conventional cleaning, frequencies are typically selected in the 20-40kHz and 68-120kHz ranges. The low-frequency range is suitable for removing contaminants with particle sizes of 3-5μm.
Main Parameters
1. Frequency: ≥20KHz, which can be divided into low, medium, and high frequency ranges.
2. Cleaning medium: Chemical solvents or water-based cleaning agents, combining chemical action with the physical effects of ultrasonic cleaning for better cleaning results.
3. Power density: Power density = transmitted power (W) / transmitted area (cm2), usually ≥0.3W/cm2. The higher the power density of ultrasound, the stronger the cavitation effect, the faster the speed, and the better the cleaning effect.
In practical applications:
Powder metallurgy parts such as magnetic cores, magnetic rings, and those with grinding magnetic powder are cleaned at frequencies of 20-25kHz;
Rough metal parts, such as automotive hubs, cylinder components, and other large parts, are cleaned at frequencies of 25-28kHz;
Watch components and precision stamped parts are cleaned at frequencies of 40kHz;
Optical glass and low-end LCD devices are cleaned at frequencies of 68-120kHz;
For cleaning semiconductor silicon wafers and LCD glass substrates to remove contaminants with particle sizes of 1-3μm, frequencies in the megahertz range of 0.8-1.0MHz are selected.
