Precision Cleaning Capabilities

The workshop uses ultrasonic cleaning tanks and controlled rinsing processes to remove contaminants from component surfaces, gaps, holes, grooves, and other difficult-to-access areas.

Depending on the component material and cleanliness requirements, the process may include:

• Pre-cleaning
• Ultrasonic washing
• Multi-stage rinsing
• Purified-water cleaning
• Controlled drying
• Visual inspection
• Clean handling and transfer
• Cleanroom packaging

Ultrasonic energy creates fine cavitation within the cleaning liquid, helping loosen particles and residues from complex surfaces without relying entirely on manual brushing or direct mechanical contact.

Typical Components

The workshop can support the cleaning of:

• PFA and fluoropolymer components
• Precision injection-molded parts
• Semiconductor-related plastic components
• Rings, fittings, and sealing parts
• Components with internal channels
• Small precision assemblies
• Parts requiring controlled surface cleanliness
• Components prepared for clean packaging

Fixtures and baskets are selected according to part geometry to keep components separated and reduce surface contact, collision, or deformation during the cleaning cycle.

Cleanroom Process Control

The cleaning area is organized to limit the introduction and transfer of contaminants during production. Operators follow controlled entry, clothing, handling, and cleaning procedures before working with processed components.

Important control points may include:

• Cleanroom clothing compliance
• Cleaning-liquid condition
• Bath temperature
• Ultrasonic cleaning time
• Rinsing sequence
• Fixture cleanliness
• Drying conditions
• Component exposure time
• Packaging and transfer methods

Parts are handled with gloves and suitable fixtures to reduce direct contact after cleaning. Cleaned components can then be transferred to inspection or packaging without returning to an uncontrolled workshop environment.

Role in Our Manufacturing Process

The Class 1,000 cleanroom cleaning workshop forms part of our integrated precision manufacturing and quality-control system.

A typical workflow may include:

1. Injection molding or component manufacturing
2. Initial appearance inspection
3. Component sorting and fixture loading
4. Multi-stage ultrasonic cleaning
5. Controlled rinsing and drying
6. Cleanroom visual inspection
7. Clean packaging
8. Final quality verification

Completing cleaning, inspection, and packaging within the same controlled environment helps reduce repeated exposure to airborne particles and supports more consistent handling between production stages.

The workshop shown represents our in-house precision cleaning capability. Actual cleaning procedures are selected according to component material, geometry, contamination type, cleanliness requirements, and packaging specifications.
