LENJEX Industrial Cleaning

Automotive Parts Ultrasonic Cleaning

Automotive component cleaning must remove mixed contamination from passages, holes and complex surfaces without slowing production flow.

Typical Workpieces

Parts in this application

  • Engine blocks and cylinder heads
  • Transmission parts
  • Bearings and gears
  • Fuel and hydraulic components

Contamination

Soils to evaluate

  • Machining oil and coolant
  • Carbon deposits
  • Metal chips and fines
  • Assembly grease
Automotive Parts Ultrasonic Cleaning process evaluation

Cleanliness Target

Define clean before choosing equipment

Acceptance may be based on visible residue, gravimetric particle limits, surface condition or downstream assembly performance.

The acceptance method should be practical for trials and production, with agreed sample handling and inspection timing.

Recommended Sequence

A process route for evaluation

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

  1. Step 1Pre-clean or spray for heavy loose soil
  2. Step 2Ultrasonic wash with selected chemistry
  3. Step 3Rinse stages to control carryover
  4. Step 4Drying matched to cavities and throughput
  5. VerifyInspect against the agreed cleanliness method.

Recommended Equipment

Systems to compare

These equipment families support the application review; 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.
