Services
Parts Cleaning
Our precision parts cleaning services utilize advanced methods like aqueous washing, ultrasonic cleaning, and vapor degreasing to remove contaminants. We meet specifications such as ISO 16232 and ASTM, ensuring components are free from particulate matter and residues. Clients benefit from validated processes and in-house laboratory testing for compliance.
Oxygen Cleaning
Oxygen cleaning services prepare components for medical, aerospace, and industrial applications by eliminating hydrocarbons and contaminants. We follow CGA G-4.1 and ASTM G93 standards, providing certification for safety-critical systems. Our clean room packaging ensures parts remain contamination-free post-cleaning.
Rust Removal
Our rust removal processes use neutral and acidic treatments to eliminate oxidation while preventing hydrogen embrittlement. This extends part longevity and ensures readiness for subsequent treatments. Clients avoid costly replacements by restoring corroded components to functional condition.
Passivation
Stainless steel passivation services meet ASTM A967 and AMS2700 specifications, creating corrosion-resistant surfaces. We ensure 100% effectiveness through rigorous testing, supporting industries requiring sterile or high-purity environments. This service enhances material durability and performance.
Laboratory Testing
Our ISO-certified lab conducts gravimetric, particle count, and NVR testing in HEPA-filtered clean rooms. Services include microscopic analysis and sealant adhesion testing, supporting OEM validation. Clients receive accurate data to verify part cleanliness and process compliance.
