High-Quality Metal Finishing Services

The three broad categories are electroplating, chemical or conversion coatings, and mechanical finishing. Electroplating deposits a metal layer for conductivity or corrosion resistance. Chemical treatments such as anodizing and chromate conversion alter the surface through chemical reactions. Mechanical methods such as polishing and bead blasting modify texture without adding material.

Cost depends on the base material, deposited metal, part geometry, and production volume. Nickel and zinc options typically run lower than chrome or gold. We provide detailed quotes based on your CAD files and volume requirements.

Surface treatments add processing time and cost to a production run. Some coatings require controlled environmental conditions during application, and improper preparation can lead to adhesion failure. Selecting the right finish for your operating environment eliminates most risks, and our verification process includes adhesion testing and dimensional inspection on every batch to catch issues before shipment.

We offer electroplating (nickel, chrome, zinc, copper in rack and barrel), anodizing, powder coating, chemical conversion including chromate and black oxide, e-coat, and passivation. The right treatment is selected for your material, operating environment, and dimensional requirements at the feasibility review.

We need your CAD files or drawings, the base material specification, the desired treatment type, required coating thickness, and annual volume. Upload your design files to start, and our team reviews initial feasibility.

Yes. Fabrication and treatment run in the same production network, which gives you a single point of accountability from raw material to completed part and removes the need to coordinate a separate finisher. Most customers ordering castings, machined parts, or fabricated components add a finish to the same run.

Coatings add material to every surface they contact, and anodizing and electrodeposition are the most common causes of tolerance issues: a bore sized exactly to print before coating may be undersized after. The fix starts at the drawing review stage. Either mask the feature to keep it bare, remove the coating requirement if it serves no function on that area, or adjust hole sizing to account for build-up before production begins. Our quality team reviews every drawing for assembly-critical features before the coating process starts.

Color variation usually traces back to two problems: relying on a RAL or Pantone code without a physical reference sample, and inconsistent pretreatment before coating. RAL and Pantone codes do not always translate exactly across different facilities. We ask for a physical sample, define the acceptable shade range, and approve pre-production color samples before the full run, with a color-match report documenting the approved shade range, so full-lot color mismatches never reach you.

Type II anodizing produces a thinner oxide layer suited for corrosion resistance and cosmetic appearance. Type III, often called hardcoat, builds a much thicker layer for wear resistance and hardness. The greater build-up of Type III requires tighter hole-sizing adjustments at the design stage, so selecting a type without accounting for thickness can cause assembly problems on precision features.
