An ultrasonic cleaner is a high-efficiency, environmentally friendly cleaning device that utilizes the cavitation effect generated by ultrasound in liquid to clean the surfaces of hardware and plastic parts. It mainly consists of an ultrasonic generator, transducer, and cleaning tank, capable of cleaning every gap and corner of complex workpieces, achieving a dead-angle-free cleaning effect.
Ultrasonic cleaners are widely used in various industries such as surface coating treatment, machinery, electronics, semiconductors, watch and jewelry, optics, textile printing and dyeing, and more. For example, in the machinery industry, they can be used to clean attachments like cutting oil, abrasive particles, iron filings, and dust; in the electronics industry, they can remove dust, oil stains, and other contaminants from the surfaces of electronic components.

Main Features
1. Thorough Cleaning Without Dead Angles: 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 cleaners are equipped with an efficient circulation and filtration system. Used cleaning solvents can be filtered through the system for repeated use, thereby saving water resources and cleaning solvents, reducing the company's cleaning costs, and enhancing its environmental image.
Ultrasonic frequency: For conventional cleaning, frequencies are typically selected between 20-40kHz and 68-120kHz. The low-frequency range is suitable for removing 3-5μm contaminant particles.
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 to achieve 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 components, such as automotive hubs, cylinder assemblies, and other large parts, are cleaned at frequencies of 25-28kHz;
For watch parts and precision stamped parts, a frequency of 40kHz is selected;
For optical glass and low-end liquid crystal devices, frequencies of 68-120kHz are used;
For cleaning semiconductor wafers and liquid crystal glass substrates to remove 1-3μm contaminant particles, megahertz-level frequencies of 0.8-1.0MHz are selected.
