Professional CNC Flange Machining Services

AOOM Technology delivers comprehensive CNC flange machining solutions engineered for demanding industrial applications. Our ISO 9001:2015 certified facility combines advanced multi-axis CNC equipment with decades of precision machining expertise, enabling us to produce components that meet the most stringent dimensional, metallurgical, and performance requirements. From design-for-manufacturability consultation through final inspection, every project benefits from rigorous process control and a commitment to continuous improvement that ensures consistent, repeatable quality across both prototype and high-volume production runs.

Flange manufacturing demands tight concentricity, perpendicularity, and gasket-surface flatness to guarantee leak-free assembly under operating pressure. AOOM's flange machining workflow addresses these requirements through dedicated fixturing, precision boring, and automated bolt-hole pattern drilling that maintains bolt-circle accuracy within ±0.05 mm across production batches. Each flange is individually verified against the applicable ASME, DIN, or JIS standard before release.

Quality Assurance

AOOM Technology operates an ISO 9001:2015 certified quality management system that governs every stage of flange production from material receiving through final packaging. Flange gasket surfaces are individually inspected for flatness and surface finish using optical comparators and profilometers, while bolt-hole patterns are verified with CMM to ensure alignment with mating flanges. Material certifications and traceability documentation accompany every shipment, providing complete accountability from raw stock to finished part. Our quality team also performs capability studies (Cp/Cpk) on critical features to ensure process stability before production release. Each flange is pressure-rated and marked in accordance with applicable ASME, DIN, or JIS specifications before shipment.
