Anodizing Services for Custom CNC Parts

One supplier for both manufacturing and anodizing finishing. Avoid the vendor blame game and get ready-to-assemble parts.

Custom Parts We Machined & Anodized

Optimized strictly for custom CNC machined and turned parts. We specialize in Type II and Type III anodizing for metals like aluminum, titanium etc. Non-standard components available.

Optical Lens Housings

Custom Bicycle Hubs

Performance Automotive Parts

Composants médicaux

Pièces décoratives

Grinder Parts

Mini aluminum hardware

Flashlight housing

A noter : First Mold provides anodizing service exclusively as a secondary finish for custom parts we machine in-house. We do not offer standalone anodizing services.

Materials We Anodize

To guarantee the highest quality and consistent results for custom CNC parts, our anodizing services focus exclusively on aluminum and titanium alloys.

Aluminum Alloys - The Industry Standard

6000 Series

6061 | 6063

Best overall anodizing performance.

7000 Series

7075

Top choice for high‑strength structural parts.

5000 Series

5052

Excellent corrosion resistance and formability.

Titanium Alloys

Our anodized titanium CNC parts are mostly used for surgical instruments, anti-galling fasteners, and high-end phone housings. Through this treatment, the titanium workpieces can achieve vibrant, fade-resistant colors for decoration or functional identification, while their surface wear resistance and corrosion resistance are significantly enhanced.

Anodizing Color Options

Anodizing service enables coloring across most color ranges, while pure white cannot be produced.

Noir

Gris

Rouge

Orange

Jaune

Vert

Bleu

Pourpre

Note for Type III Hardcoat: Due to the dense oxide layer, Type III anodizing typically results in a Dark Gray, Bronze, or Black finish. Vibrant colors are generally not available.

Type II vs. Type III For Your Metal Parts

We provide both standard and hardcoat anodizing. Choose based on your part's functional environment. Our project manager will also provide you with guidance.

Fonctionnalité	Type II: Standard Anodizing	Type III: Hardcoat Anodizing
Primary Goal	Aesthetics, Corrosion Resistance	Extreme Wear Resistance, Hardness
Coating Thickness	0.0001″ to 0.001″	0.0005″ to 0.004″
Color Options	Full Spectrum	Dark Gray, Bronze, Black
Dimensional Impact	Minime	Significant – Requires CNC Allowance
Meilleur pour	Consumer electronics, enclosures, cosmetic parts	Gears, sliding parts, tactical components

Precision Control & Custom Masking

Anodizing service utilizes masking techniques to shield specific zones from anodic oxidation.

CNC Dimensional Allowance

Our CNC and surface finishing teams are perfectly coordinated. As early as the CAM programming stage, we can calculate the thickness increase from the anodizing layer. Part tolerances will not be compromised by the anodizing service.

Custom Masking Capabilities

Critical features of the part are kept in their original state. Threaded holes, internal threads, and bearing mating surfaces are common examples. During the anodizing process, we protect these surfaces using custom silicone plugs and other methods.
