Our Custom Surface Capabilities

From micro-level protective chemical layers to highly durable powder resins, we provide specialized post-processing lines matching global OEM tolerances.

**

Anodizing (Type II & III)

Primarily optimized for Aluminum CNC elements. Develops a hard, highly wear-resistant oxide shell layer. Type III (Hard Anodizing) provides severe scratch shielding. Spec: Up to 50μm Thickness

**

Powder Coating

Deployable across all structural casting metals in thousands of RAL and Pantone textures. Superior high-impact absorption properties and UV stabilization setups. Spec: Outstanding Impact Resistance

**

E-Coating

The global framework standard for structural automotive components. Delivers complete, even distribution coverage into extreme blind recesses and deep cavities. Spec: 1000+ Hrs Salt Spray Confirmed

**

MAO / PEO Coating

Advanced Micro-Arc Oxidation customized for Magnesium alloys. Generates an ultra-hard, crystalline ceramic infrastructure resisting direct heat and chemical erosion. Spec: Ceramic Hardness for Magnesium

**

Chromate Conversion

Commonly known as Alodine passivation. Establishes a highly receptive base priming platform for downstream painting while maintaining component electrical conductivity. Spec: RoHS/REACH Chrome-Free Compliant

**

Blasting & Polishing

Controlled mechanical blasting sweeps to attain customized micro roughness values ($R_a$) or highly uniform matte/brilliant mirror surface cosmetic profiles. Spec: Tailored Ra Roughness Control

Validated Quality Standards

We do not just perform coating application runs; we meticulously audit each chemical layer’s structural integrity to verify long-term protection.

• Salt Spray Testing (ASTM B117) Subjecting sample batches from 48 up to 1000+ hours to track accelerated environmental oxide resistance.
• Cross-Hatch Adhesion Testing Strict blade tape scoring evaluations confirming mechanical cohesion limits over the base metal substrates.
• Micron-Level Thickness Control Precision non-destructive inductive probe measurements tracking correct cross-sectional film profiles.
• Precise Digital Color Matching Utilizing sophisticated spectrophotometer validation pipelines to maintain strict brand batch-to-batch consistency.

Frequently Asked Questions

How do you ensure magnesium parts don’t corrode in salt-spray environments?

Magnesium is highly reactive, requiring a specialized multi-layer strategy. We prime the raw substrate using either advanced Micro-Arc Oxidation (MAO) or high-grade non-chrome conversion layers. This is instantly paired with highly uniform e-coating or specialized exterior-grade powder resins. This comprehensive layering configuration routinely passes 720 to 1,000+ hours of continuous ASTM B117 salt spray exposure without base metal pitting.

Are your surface treatments RoHS and REACH compliant for international shipping?

Yes, absolutely. All our post-processing lines utilize 100% hexavalent chrome-free, lead-free chemical conversion and passivation technologies. We issue full technical documentation ensuring your precision batches comply with modern environmental export directives targeting both European and North American customs entry ports.

Can you match specific brand colors and gloss percentages for metal enclosures?

We provide full verification matching based on global standard codes (RAL, Pantone) or directly from physical master samples sent to our labs. Every incoming color configuration passes through spectrophotometer tracking instruments to evaluate delta-E tolerances, guaranteeing tight gloss and shade alignment across your entire mass production run.
