Stamping & Sheet Metal Ultrasonic Cleaning
Removes drawing oil, stamping lubricant and fines from stamped and sheet-metal parts in high volume.
Why Ultrasonic
Ultrasonic cleaning for Stamping & Sheet Metal
Stamped and sheet-metal parts carry drawing and stamping oil, lubricants, fines and sometimes light rust. Ultrasonic cleaning lifts these soils from creases, drawn features and the surfaces of nested or stacked parts, with oil skimming to keep the bath usable.
The work is closely tied to degreasing and oil and grease removal. A ultrasonic cleaner with filtration suits batch work, while a rotary basket line or mesh-belt line handles continuous high volume.
Oil loading, nesting and any corrosion risk are reviewed before choosing the stage and chemistry.
- Lifts drawing oil from nested and drawn parts
- Oil skimming extends bath life
- Cleaning of creases and formed features
- Batch or continuous high-volume options
- Prepares a clean surface for plating or coating
Typical Workpieces
Parts in this application
- Drawn and deep-drawn parts
- Brackets and sheet-metal housings
- Stamped panels and covers
- Nested and progressive-die parts
- Metal clips and springs
- Sheet-metal assemblies
Contamination
Soils to evaluate
- Drawing and stamping oil
- Stamping lubricants
- Metal fines and burrs
- Rust-prevention oil
- Polishing compound
- Light corrosion and oxidation
Cleanliness Target
Define clean before choosing equipment
Acceptance is based on surface cleanliness, oil checks and freedom from corrosion, often ahead of plating, coating or assembly.
Rust inhibitors or prompt drying may be needed for ferrous parts.
Recommended Sequence
A process route for evaluation
The final sequence depends on soil loading, material, rinse quality and drying behavior.
- Step 1Pre-skim or drain heavy oil
- Step 2Ultrasonic wash with filtration and skimming
- Step 3Rinse stages
- Step 4Dry with rust protection as needed
- VerifyCheck surface cleanliness and corrosion
Recommended Equipment
Systems to compare
The final specification follows process testing and production analysis.

View configurationProcess 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.
- DescribePart, material and contamination.
- LoadUse realistic spacing and orientation.
- TestRecord chemistry, time and temperature.
- VerifyInspect with the agreed method.
Application Questions
Planning the cleaning study
Include normal production parts and the most difficult expected geometry or contamination so the process is not based on an easy sample.
Provide part dimensions, material, soil, cleanliness target, parts per load, required output and available utilities.
Parts are arranged to allow liquid exchange, with filtration and oil skimming; continuous lines tumble or convey parts to expose nested surfaces.
It can if left wet. Prompt drying, rust inhibitor or controlled handling protect ferrous parts until plating or assembly.
High-volume stamping usually moves to a mesh-belt or rotary-basket line, while a single-tank machine suits batches and mixed parts.
