Comprehensive Automotive Metal Finishing

Automotive clients partner with Diamond Metal Finishing to simplify complex workflows, ensure compliance with finishing specifications, and enhance part longevity and appearance. We integrate multiple finishing services under one roof — reducing transit time, rework, and vendor coordination.

✦ Automotive Anodizing (Type II & Type III)

Aluminum parts across powertrain, body, and accessory applications benefit from anodizing for both function and finish.

• Type II Anodizing: Used for corrosion resistance and appearance on trim pieces, emblems, enclosures, and brackets.
• Type III Hardcoat Anodizing: Suitable for high-wear and thermally exposed parts including actuator housings, engine covers, and chassis mounts.
• Available in clear, black, and dyed finishes. Consistent layer thicknesses ensure dimensional control.
• Conforms to MIL-A-8625 and ISO process guidelines.

✦ Automotive Powder Coating

Our powder coating services ensure durable protection for structural and aesthetic components used throughout the vehicle.

• Coatings meet OEM standards for adhesion, abrasion, and weather resistance.
• Used on underbody panels, interior supports, roll cages, and decorative brackets.
• Available in custom textures and colors to match vehicle branding or performance needs.
• Multi-coat options available to support salt spray or high-moisture conditions.

✦ Automotive Laser Engraving

Engraving is used throughout automotive assemblies to mark safety-critical and traceable components with permanent data.

• Mark serial numbers, VIN plates, spec identifiers, and branding elements.
• Deep engraving available for high-abrasion or under-hood applications.
• Compatible with aluminum, stainless, powder-coated parts, and plastics.

✦ Automotive Screen & Digital Printing

We offer functional and aesthetic printing services to support control labels, fascia, overlays, and branded visuals inside and outside the vehicle.

• Screen printing for single-color graphics with high adhesion and durability.
• Digital printing for multi-color designs and short-run production.
• UV and solvent-resistant inks used for longevity under sunlight and fluids.

✦ Automotive CNC Routing

Precision routing services help form and finish interior panels, enclosure cutouts, and custom prototype parts in automotive plastics and metals.

• Routed materials include aluminum, G10, Glastic, polycarbonate, and acrylic.
• Used for dash panels, door inserts, brackets, and fuse box covers.
• Supports high-accuracy tolerances required in assemblies.

✦ Automotive Chemical Conversion Coating (Chem Film)

Ideal for multi-metal assemblies or pre-treatment, chem film ensures reliable corrosion resistance and bonding integrity across conductive parts.

• Class 1 and Class 3 chem films using Iridite and Alodine systems.
• Common for grounding zones, enclosures, and fasteners.
• Used standalone or as primer for painting or powder coating.
