Our Surface Treatment Capabilities

CHX Metal provides comprehensive surface treatment and metal finishing services, ensuring your precision parts meet exact specifications for appearance, corrosion resistance, wear resistance, and electrical conductivity.

Anodizing

Type II and Type III hard anodizing for aluminum alloys. Improves surface hardness up to 60-70 HRC, provides excellent corrosion resistance, and offers decorative color options.

Type II standard anodizing (5-25μm)
Type III hard anodizing (25-75μm)
Color anodizing: black, red, blue, gold
Sealing and non-sealing options

Electroplating

Precision electroplating services for enhanced wear resistance, electrical conductivity, and solderability.

Nickel plating (electroless & electrolytic)
Chrome plating (hard chrome)
Zinc-nickel alloy plating
Gold and silver plating (for electronics)

Powder Coating

Durable powder coating providing excellent impact resistance, chemical resistance, and aesthetic finishes in virtually any color.

Electrostatic powder coating
Epoxy, polyester, and hybrid powders
Thickness: 60-120μm
Gloss, matte, and texture finishes

Electrophoretic Coating (E-Coating)

Uniform coating even on complex geometries. Excellent corrosion protection for automotive and industrial applications.

Cataphoretic (cathodic) E-coating
Film thickness: 10-35μm
Edge and crevice coverage
Black, white, and clear options

Quality Assurance

All surface-treated parts undergo rigorous quality inspection including:

Coating thickness measurement (X-ray and magnetic gauge)
Adhesion testing (tape test, impact test)
Corrosion resistance testing (salt spray test per ASTM B117)
Surface roughness measurement
Visual and dimensional inspection

Applications

Our surface treatment services serve precision parts across automotive, electronics, medical devices, optical communications, aerospace, and industrial automation sectors.
