LENJEX Industrial Cleaning

Jewelry & Watches Ultrasonic Cleaning

Gentle cleaning of rings, chains, watch bands and small components to restore shine without hand polishing.

Why Ultrasonic

Ultrasonic cleaning for Jewelry & Watches

Jewelry and watch parts collect polishing compound, dirt, skin oils and residues in settings, chains and links. Gentle 40 KHz cavitation cleans these recessed areas without the contact and wear of hand polishing, restoring shine quickly.

A compact benchtop cleaner is the standard choice, with a small basket and mild compatible chemistry. Retail counters and workshops commonly use the same equipment for both jewelry and watch bands.

Gemstone and material compatibility should be checked before cleaning, as some settings and stones are not suited to ultrasound.

Cleanliness Target

Define clean before choosing equipment

Acceptance is visual: restored shine with no residue in settings or links and no change to the stone or setting.

Soft or fragile stones are excluded or handled separately.

Recommended Sequence

A process route for evaluation

The final sequence depends on soil loading, material, rinse quality and drying behavior.

  1. Step 1Check gemstone and material compatibility
  2. Step 2Clean in mild chemistry at 40 KHz
  3. Step 3Rinse to remove residues
  4. Step 4Dry and inspect settings
  5. VerifyConfirm shine and stone condition

Recommended Equipment

Systems to compare

The final specification follows process testing and production analysis.

Process Controls

Control the variables that change the cleaning result

Confirm the part, soil, loading and final handling before fixing equipment settings.

Control 01

Material and geometry

Record surfaces, cavities and features that can trap air or liquid.

Control 02

Soil condition

Test the heaviest representative contamination, not an ideal sample.

Control 03

Basket loading

Keep acoustic access and part spacing consistent with production.

Control 04

Rinse and drying

Match downstream handling to residue and corrosion risks.

System Selection

Match the cleaning route to production flow

Stage count and automation follow the validated process and required output.

Batch

Single-tank route

Compare for focused washing where rinsing and drying are managed separately.

Multi-stage

Wash, rinse and dry

Add controlled stages when carryover and final condition matter.

Automatic

Repeatable transfer

Evaluate automation when output, handling or recipe control requires it.

Acceptance

Define how the cleaned part will be checked

Use the same practical inspection method for trial samples and production parts.

  • Agree the surface or residue limit
  • Check hidden and difficult features
  • Record rinse, drying and handling conditions
  • Compare results before the next operation

Representative Trial

Confirm the process with real parts and loads

Trial evidence should cover normal production and the most difficult expected condition.

  1. DescribePart, material and contamination.
  2. LoadUse realistic spacing and orientation.
  3. TestRecord chemistry, time and temperature.
  4. VerifyInspect with the agreed method.
