Custom CNC-Machined Flanges

When standard flanges limit design flexibility, custom-machined solutions allow exact fit and functional accuracy. Our Custom CNC-Machined Flanges follow client drawings, combining multi-axis machining and tight tolerances for exact form and function. 
Inconsistent mating or pressure issues lead to frequent replacements and downtime. We machine every unit from billet or forged blanks, supporting high-stress, high-temperature, or corrosion-prone systems. 

Standard Specification

Custom per engineering drawings [Can reference ASME/API/DIN as baseline]

Pressure Rating

Custom (typically Class 150-4500 / PN10-PN700) [FEA-verified]

Material

Any machinable alloy: Titanium (Gr.2/5), Inconel (625/718), Aluminum (6061-T6), Composites

Nominal Size

0.5″ to 120″ (DN15-DN3000) [No standard size limitations]

Flange Type

Fully custom (Integral hubs, Vanstone, Split-ring designs)

Product Description

Inconsistent mating or pressure issues lead to frequent replacements and downtime. We machine every unit from billet or forged blanks, supporting high-stress, high-temperature, or corrosion-prone systems.

Facing Type

Custom profiles (Grooved, Tongue-and-groove, Metal-to-metal)

Dimensions

±0.005″ tolerance

Bolt Circle Diameter

Custom patterns [Eccentric/offset designs possible]

Number & Size of Bolt Holes

Non-standard configurations [Keyed slots/oval holes available]

Surface Finish

8-32 μin Ra (mirror finish), Micro-textured [EDM/laser options]

Corrosion Resistance

Custom cladding (Hastelloy, Stellite), PVD coatings

Temperature Rating

-452°F to +2000°F (-269°C to +1093°C) [Material-dependent]

Material Certification

Full traceability (PMI, UT, RT), NADCAP-certified processes

Gasket Compatibility

Custom gasket profiles [Including metal C-rings, spring-energized seals]

Coating/Plating

DLC (Diamond-Like Carbon), Teflon-impregnated, Ceramic thermal spray

Manufacturing Method

5-axis CNC machining [From billet/forging]

Technical Advantages

Standard fittings can’t match unique layouts or advanced pressure boundaries. Our flanges allow non-circular bolt patterns, eccentric layouts, and internal fluid channels based on drawing inputs. 
We machine profiles such as tongue-and-groove, metal-to-metal, or recessed seal cavities for critical sealing. Surface finish options like PVD, DLC, or micro-texture support friction control or corrosion protection.

Industry Applications

Cryogenic Valve Systems

CNC-milled flanges in Inconel or Monel support -250°C service in LNG and industrial gas handling units. 

Space Vehicle Components

Titanium Grade 5 flanges withstand thermal shock and vibration during launch sequences and orbital operations. 

Offshore Subsea Assemblies

Cladded designs with Stellite overlays resist saltwater erosion and pressure cycling in deep-sea pipelines. 

High-Temperature Furnaces

Custom profiles with ceramic coatings endure over 1800°F in metallurgical and sintering systems.

Semiconductor Equipment

Ultra-smooth Ra 8 finishes prevent contamination during gas transfer in vacuum deposition machines.

Nuclear Reactor Modules

NADCAP-certified components ensure metallurgical integrity and meet ASME Section III nuclear safety codes.

Custom CNC-Machined Flanges

Fit-to-Function Manufacturing for Specialized Systems

Engineered assemblies need flanges built to the exact drawing, without tolerance stack-up or sealing mismatch. Our custom machining setups handle one-off units or short-run series with full traceability and material verification. 
Each part ships with dimensional reports and certifications that match your industry or regulatory need. We help reduce rejection rates, minimize rework, and speed up system integration for high-value assemblies.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can you match our internal sealing groove dimensions exactly?

Yes, we follow client-provided CAD or 2D drawings to machine grooves to within ±0.005 inch tolerance. We also validate groove finish with profilometers to meet Ra specifications. This ensures full sealing performance without manual correction on-site.

Do you support small-batch or one-off production for R&D projects?

We accept quantities as low as a single unit for testing or prototyping needs. Each unit receives the same traceability and dimensional reporting as production runs. This helps you validate critical fit or performance before committing to larger orders.

Can we request mixed material or cladded flange structures?

Yes, we offer dissimilar metal combinations such as Inconel cladded over carbon steel or Stellite overlays on pressure faces. Our weld-overlay process ensures bonding integrity and corrosion resistance. These are suitable for heat exchangers or high-wear piping.

How do you control tolerance stack-up in multi-surface machined flanges?

We use 5-axis machining centers with in-process probing to eliminate cumulative error. All critical dimensions are verified with CMM before release. This gives consistent fitment in precision assemblies like rotating equipment or valve bodies.

Can you support eccentric or offset bolt hole patterns for non-standard flange assemblies?

Yes, we machine custom bolt circles including offset or slotted hole layouts as per your drawings. We also check alignment using digital templates during QC. This allows hassle-free integration with mismatched or retrofitted equipment.
