Ultrasonic Mold Cleaning Machine uses high-frequency sound waves to remove mold residues and fouling from tooling and plates that are immersed in a heated aqueous solution. An ultrasonic generator converts standard line-frequency current into high-frequency electrical energy. The generator is connected to small transducers that are mounted to the bottom or sides of a wash tank. These transducers vibrate at ultrasonic frequencies when the current passes through. This causes the bottom or sides of the tank to vibrate like the diaphragm in a speaker,which scrub and loosen vent residues and grime.
