Ultrasonic Cleaner

A jewelry ultrasonic cleaner uses high-frequency sound waves in a liquid bath to lift soil from jewelry surfaces and narrow crevices. Typical tasks include removing polishing compounds, skin oils, and workshop residues. This type of equipment is applied in studios, repair benches, and retail backrooms as part of a standardized cleaning workflow.

Advantages

Typical configurations include a stainless-steel tank, lid, basket, heater, timer, and drain valve. Digital or analog controls allow adjustment of time and temperature. Baskets suspend items to limit contact with the tank walls. Fill markings, detachable power cords, and optional degas functions support routine operation. Bench units commonly range from 0.6 to 10 liters, with capacity selected according to batch size and fixture requirements.

Selection Criteria

When evaluating an ultrasonic cleaning system for jewelry work, review:
Tank Capacity & Footprint: Ensure internal dimensions accommodate trays, holders, and the largest pieces to be processed.
Frequency & Power Profile: Confirm operating frequency and rated power per liter for consistent results.
Temperature Control: Many detergents function within defined temperature ranges; accurate heating supports this.
Baskets & Accessories: Check mesh size, watch holders, and beaker racks for specific tasks.
Drainage & Maintenance Access: Drains and removable lids simplify fluid changes and tank cleaning.

Application Range

This ultrasonic cleaner supports cleaning of rings, chains, settings, and watch cases with movements removed. It is often used between process steps—after polishing, before plating, or prior to inspection—where residue reduction supports surface preparation. For gemstones, material suitability should be confirmed, as some porous or fracture-filled stones are not recommended for ultrasonic exposure.

Buying Considerations

Before purchasing ultrasonic cleaner for jewelry, review input voltage, plug type, tank material grade, and manufacturer guidance on compatible detergents. Check sonic power rating, duty cycle, and frequency tolerance for daily use. Lid fit, basket quality, and sealing around controls help manage splashing. Availability of spare parts such as baskets, heaters, transducers, and gaskets supports long-term operation.
