Industrial Ultrasonic Cleaning Machine Series

Industrial ultrasonic cleaning machines use high-frequency cavitation generated by immersing transducers in a heated cleaning solution to remove oil, wax, polish residue, rust and flux from parts of almost any geometry. Cleaning reaches blind holes, threads and internal channels that spray washing cannot reach.

Longyanxing ultrasonic cleaners range from 33 L bench units to 96 L and larger industrial tanks, with digital heating, degas and sweep-frequency generators, stainless steel tanks and optional filtration, oil skimming and rinsing stages. They serve hardware, automotive, mould and die, jewellery, optics and electronics workshops.

Select the right frequency for your soil: 28 kHz for heavy oil and chips, 40 kHz for general cleaning, and higher frequencies for fine and delicate parts. Tell us your parts and contamination and we will size the tank and recommend a chemistry.

Frequently Asked Questions

What does an ultrasonic cleaning machine remove?

An ultrasonic cleaner uses high-frequency sound waves to create microscopic bubbles that implode against the part surface, lifting contaminants from every exposed area. It removes polishing compound, oil, grease, wax, rust residues, oxide and fine particles, including from blind holes, threads and complex internal geometry.

Which ultrasonic frequency should I choose?

Lower frequencies around 28 kHz produce larger, more energetic bubbles that remove heavy soil and scale quickly. Higher frequencies from 40 kHz upward produce gentler, denser cavitation that is safer for delicate surfaces, fine finishes and jewellery. Many industrial units combine frequencies so one tank handles both cleaning stages.

Why is ultrasonic cleaning important after polishing?

Polishing leaves wax, compound and abrasive residue in recesses that manual wiping misses. Ultrasonic cleaning removes it completely, so the part is ready for inspection, plating, coating or assembly without contamination. This is essential for jewellery, medical and precision components where residue causes rejects.
