Surface Finishing

Our Surface Treatment Capabilities

Whether you need a decorative mirror finish or industrial-grade corrosion protection, Honjenny delivers consistency across six major finishing categories.

Shot Blasting

The ideal pre-treatment to remove flash and burrs. It creates a uniform matte surface and compacts the outer layer to improve fatigue strength.

Precision Sandblasting

Creates a fine, consistent texture. We offer various bead sizes to achieve specific roughness (Ra) requirements, perfect for preparing surfaces for painting or anodizing.

Coating & Wet Painting

From durable powder coating for outdoor use to high-gloss wet paint for electronics. We color-match to any RAL or Pantone code.

Anodizing

Primarily for Aluminum parts. It creates a hard, wear-resistant oxide layer that protects against corrosion and provides electrical insulation.

E-Coating (Electrophoresis)

Immersion painting that guarantees 100% coverage, even inside deep threads and cavities. Excellent as a primer or a standalone corrosion-resistant finish.

Electroplating (Chrome/Nickel/Zinc)

Provides a metallic, conductive, and decorative finish. We offer Chrome for mirror-like looks, Nickel for wear resistance, and Zinc for rust protection.

The Honjenny Finishing Standard

We ensure the coating adheres perfectly to the casting.

  • Superior Adhesion

    We control the substrate quality. By ensuring the raw casting is clean and porous-free, we guarantee coatings pass the Cross-Cut Tape Test (ISO 2409).

  • In-House Validation

    Every batch undergoes strict testing in our lab, including Salt Spray Testing (up to 720+ hours) and coating thickness measurement.

  • Visual Consistency

    We use colorimeters to ensure ΔE < 1.0, guaranteeing that parts from different batches look exactly the same when assembled.

Finishing Applications

Meeting the visual standards of Consumer Electronics and the durability standards of Automotive industries.

Verified Quality Assurance

At Honjenny, surface finishing is science, not art. Our Quality Lab is equipped to verify that our finishes can withstand the harshest environments.

Customer Success Stories

Feedback on our finish quality.

“We used to have issues with paint peeling off our outdoor housings. Honjenny suggested a specific shot blasting pre-treatment before powder coating, and now our products survive 5 years outdoors without fading.”

Daniel R.
Quality Director

“The visual appeal of our audio equipment is crucial. Honjenny achieved a flawless Champagne Gold anodized finish that set our product apart. Their control over color consistency from batch to batch is something we haven’t found elsewhere.”

Jack L.
Product Design Lead

“Corrosion resistance was our top priority for this marine bracket. Honjenny provided an E-coating solution that passed our 72-hour salt spray test. Plus, their precision masking meant we didn’t have to re-tap threads during assembly—a huge time saver.”

Alex P.
Senior Mechanical Engineer

Finishing Workflow

Ensuring the look you want.

01

Sample Matching Content
You send us a color chip (Pantone/RAL) or a physical sample. We create a tailored finish to match it.

02

Performance Testing Content
Before mass production, we run adhesion and environmental tests (Salt Spray, UV) to validate the finish durability.

03

Visual Inspection Content
Final production parts undergo 100% visual inspection under controlled lighting to ensure no scratches, bubbles, or flow marks.

Frequently asked questions

Yes, for Powder Coating and Wet Painting, we can match any RAL or Pantone color code. For Anodizing, we offer standard colors (Black, Natural, Red, Blue, Gold).

It depends on the process. Our standard Powder Coating passes 500-1000 hours. Zinc Plating typically passes 48-96 hours (up to 240h with sealer). E-coating passes 500+ hours.

Yes, all our surface treatments, including Trivalent Chromate (Cr3+) plating and lead-free paints, are fully RoHS and REACH compliant for global markets.

Yes, but ADC12 contains high Silicon content, which turns the surface dark or yellowish-grey during anodizing. It is excellent for corrosion protection but not recommended for cosmetic parts requiring a clear, bright, or uniform metallic finish. We can advise on the best alloy or alternative finish for your visual needs.

Typically 60-80 microns, but we can adjust this based on your assembly tolerances.

Absolutely. Honjenny designs custom silicone plugs and masking fixtures to ensure threads and grounding points remain free of paint/plating.
