Wave cleaning is to use the energy characteristics of ultrasonic waves to act on the workpiece in the cleaning medium through its mechanical effect and "cavitation effect" to achieve rapid and efficient cleaning. In particular, ultrasonic waves are penetrative and have irreplaceable advantages for the cleaning of micro-holes and blind holes. Ultrasonic cleaning is a necessary means for the regeneration of polyester melt filter cores, spinning spinnerets and other components in the chemical fiber industry. It is an important way to save costs, reduce energy consumption, reduce labor intensity and improve product quality.
