The Ultrasonic washing machine is designed to use the cavitation effect generated by the application of ultrasonic waves in the cleaning fluid, which can accelerate the dissolution and decomposition of dirt and grease in the cleaned parts, and has a perfect cleaning effect on the blind holes and internal holes of the container. The cleaning speed is fast, the efficiency is high, the surface is not damaged, and the labor intensity is reduced. It is cleaning precision mechanical parts, hydraulic parts, pneumatic parts, valves, brakes, bearings, bearing scrapers, oil nozzles, oil pumps, carburetors, injectors and others Electronic parts, circuit boards, semiconductor silicon wafers, electroplating, optical lenses, audio heads, polyester filters, chemical fiber spinning nozzles, spinning plates, etc., including laboratory cleaning and other industries. There are machines with different functions, such as heating, power adjustment, dual frequency, high frequency (59K, low noise, suitable for precision cleaning) and sweep frequency for users to choose.
