What Is Cleanliness Testing for Machined Parts?
Cleanliness testing is a controlled inspection process that measures the amount and type of residual contaminants, such as particles, fluids, or debris, remaining on a machined part after cleaning.
At C. Thorrez Industries, this testing is an essential step following processes like CNC machining, ultrasonic washing, and assembly. We use validated inspection techniques to detect and quantify microscopic contaminants, ensuring your parts meet industry-specific cleanliness requirements.
Our testing protocols are based on customer specifications, industry standards, and critical performance requirements.
Why Cleanliness Testing Matters in Precision Machining
Contamination can jeopardize product performance, assembly integrity, and regulatory compliance. That’s why cleanliness testing is a core part of our precision machining workflow, especially for components used in demanding environments.
Our cleanliness testing helps ensure:
- Functional reliability in hydraulic and fuel systems
- Compatibility with sterile and biocompatible applications
- Smooth fit and sealing in tight-tolerance assemblies
- Protection of coatings, adhesives, or secondary finishes
We don’t guess—our data-backed processes give customers confidence that their parts are not just clean, but certifiably clean.
How Cleanliness Testing Works at C. Thorrez
Our process is tailored to the part’s geometry, material, and application. It typically includes:
- Sample Preparation – After final machining and ultrasonic cleaning, parts are handled with care in a controlled environment to avoid recontamination.
- Extraction Method – Parts are flushed, sprayed, or immersed in a certified solution to remove any residual contaminants.
- Particle Collection & Measurement – We analyze the solution using filtration, gravimetric analysis, or microscopy to detect particles by size, shape, and composition.
- Reporting & Documentation – Test results are recorded and compared against defined cleanliness criteria. If required, cleanliness certificates are included with the shipment.
Applications Across Industries
Our cleanliness testing process is trusted by clients in high-precision sectors that demand zero-compromise performance:
- Aerospace & Defense – Ensuring critical systems function without failure
- Medical Devices – Verifying sterility and biocompatibility for implants and surgical tools
- Automotive Powertrains – Preventing wear or failure due to particle contamination
- Fluid & Hydraulic Systems – Confirming that valves and seals operate as intended
Whether your component lives in a jet engine or a life-saving device, we ensure it meets its cleanliness spec.
