Comprehensive OEM Metal Finishing

OEM partners choose Diamond Metal Finishing for our ability to manage diverse component geometries, finish requirements, and production volumes—all under one roof. Our controlled processes ensure compatibility, traceability, and compliance throughout the supply chain.

✦ OEM Anodizing (Type II & Type III)

We anodize aluminum components for appearance, corrosion protection, electrical insulation, and durability across OEM applications.

• Type II Anodizing: Provides cosmetic and protective finishes for panels, bezels, and branding plates.
• Type III Hardcoat Anodizing: Used on housings, mounts, and sliding interfaces needing abrasion and wear resistance.
• Available in clear, black, and custom-dyed options. Conforms to MIL-A-8625.

✦ OEM Powder Coating

Powder coating provides a robust and aesthetically flexible solution for OEM parts subject to mechanical use or environmental exposure.

• Meets AAMA and ASTM standards for color stability, adhesion, and durability.
• Custom color matching for brand requirements or part differentiation.
• Used for enclosures, structural frames, brackets, and external casings.

✦ OEM Laser Engraving

Laser marking enables permanent part identification for warranty tracking, regulatory compliance, and brand security.

• Mark part numbers, serial IDs, QR codes, and logos directly on metal or plastic parts.
• High-contrast engraving on anodized, powder-coated, or bare materials.
• Used across mechanical assemblies, housings, and customer-facing interfaces.

✦ OEM Screen & Digital Printing

We support OEM visual and functional printing needs including front panel interfaces, overlays, legends, and product branding.

• Screen printing for high-durability, single-color graphics on enclosures and controls.
• Digital printing for multi-color logos, panel layouts, or instructional markings.
• Compatible with aluminum, stainless, plastics, and coated parts.

✦ OEM CNC Routing

Precision CNC routing enables the creation of component forms, enclosures, and mounting hardware for OEM assemblies.

• Routing services for aluminum, polycarbonate, G10, Glastic, and acrylic.
• Used to cut panels, faceplates, gasket outlines, and mounting plates.
• Supports low-volume prototypes through full production runs.

✦ OEM Chemical Conversion Coating (Chem Film)

Chem film treatment provides conductive corrosion resistance and serves as a primer layer for painted or coated OEM parts.

• Clear and gold options available (Class 3 and Class 1 chem film).
• Used on sensor housings, multi-metal frames, and electronic subassemblies.
• Meets MIL-DTL-5541, RoHS, and REACH requirements.
