Metal Finishing Companies

Last updated: January 2026

This directory lists 130 metal finishing companies across the United States, from specialty coaters focused on PVD/CVD and thermal sprays to high-volume plating lines for zinc dichromate and cadmium.

Buyers engage metal finishing companies to address a spectrum of critical engineering problems: enhancing corrosion resistance in harsh environments, increasing surface hardness for wear applications, improving lubricity, ensuring electrical conductivity or insulation, and achieving precise aesthetic finishes. Key challenges often revolve around achieving uniform coating thickness, optimizing adhesion to the substrate, and managing precise masking requirements for selective finishing.

Suppliers in this space vary significantly. You'll find general job shops handling a wide array of common finishes like electroplating, anodizing, and passivation. Then there are highly specialized facilities focusing on niche processes like vacuum metallization, e-coating, or specialized chemical conversion coatings. Some operate massive automated lines for automotive or general industrial volumes, while others excel in small-batch, high-precision finishing for medical devices or aerospace components, often with stringent Nadcap or AS9100 certifications.

To engage effectively, buyers should come prepared with detailed engineering drawings, material certifications for the base substrate, precise specification call-outs (e.g., AMS, ASTM, Mil-Spec), desired quantity, and realistic lead time expectations. Suppliers, in turn, will expect clear instructions regarding critical dimensions post-finishing, areas requiring masking, and any specific pre-treatment or post-treatment requirements, such as hydrogen embrittlement relief or specific bake cycles.

A significant trend in the metal finishing sector is the continued shift away from hexavalent chrome processes towards more environmentally friendly alternatives like trivalent chrome, particularly in automotive and consumer electronics. There's also growing investment in automation, advanced process control, and real-time thickness monitoring to ensure greater consistency, reduce waste, and meet increasingly tight tolerances for demanding applications.

How to Choose a Company

  • Verify the supplier's specific process capabilities and tank sizes, ensuring they can physically handle your parts for processes like Type II or Type III hardcoat anodizing, or have adequate barrel capacity for small-part electroless nickel plating.
  • Demand proof of adherence to relevant industry specifications such as AMS 2404 for Electroless Nickel, ASTM A967 for Passivation, or MIL-DTL-5541 for Chromate Conversion Coating, rather than just general claims of quality.
  • For aerospace, defense, or critical medical applications, insist on Nadcap accreditation (e.g., AC7108 for chemical processing, AC7110 for coatings), not merely ISO 9001 or AS9100, which are broader quality system certifications.
  • Inquire deeply about their masking capabilities and expertise; complex geometries or selective plating require highly skilled technicians and appropriate masking materials to protect specific areas from the finish.
  • Assess their pre-treatment line: the effectiveness of cleaning, degreasing, and etching steps directly impacts coating adhesion, uniformity, and prevents common issues like blistering or peeling post-finishing.
  • Be wary of suppliers who don't proactively ask about your post-finishing dimensional tolerances or the need for hydrogen embrittlement relief for high-strength steel, indicating a potential lack of critical process understanding.
  • Review their quality control protocols specifically for metal finishing, including their methods for measuring coating thickness uniformity (e.g., XRF, eddy current), adhesion testing (e.g., cross-hatch, bend test), and salt spray testing (ASTM B117) frequency.

Frequently Asked Questions

What's the difference between Type II and Type III hardcoat anodizing, and when should I use each?

Type II (sulfuric acid anodizing) provides good corrosion resistance and is ideal for dyeing, yielding a cosmetic finish typically between 0.0001-0.001 inches thick. Type III (hardcoat anodizing) uses higher current densities and lower temperatures, resulting in a much harder, denser, and thicker (0.001-0.003 inches) coating primarily for wear resistance, abrasion protection, and electrical insulation. Use Type II for general protection and aesthetics, and Type III for components requiring extreme durability and hardness.

How do I prevent hydrogen embrittlement when plating high-strength steels?

High-strength steels (typically Rockwell C 35 or higher) are susceptible to hydrogen embrittlement when exposed to hydrogen atoms during plating. The critical prevention step is a post-plating bake: components must be baked at a specified temperature (e.g., 375°F for 3 hours) within a very short timeframe (typically 1-4 hours) after plating. Ensure your supplier has a certified baking oven and adheres to precise timing and temperature requirements per relevant specifications like ASTM B850 or AMS 2759/9.

What specific drawing call-outs are essential for getting an accurate quote for passivation?

For passivation, specify the base material (e.g., 303, 304, 316 stainless steel), the passivation specification (e.g., ASTM A967 (Nitric or Citric Acid Method), AMS 2700), and any post-passivation testing requirements (e.g., salt spray, humidity test, copper sulfate test per ASTM A380). Clearly indicate if the part has been machined or heat-treated, as this can affect the surface condition and passivation method required.

Can all metal finishing shops handle my complex masking requirements for selective plating?

No, not all shops possess the expertise or equipment for complex masking. Selective plating often requires intricate masking techniques using waxes, tapes, lacquers, or custom-fit fixtures to protect specific areas from the finish. It's crucial to discuss your masking needs upfront, provide clear drawings showing areas to be coated and areas to be masked, and verify the supplier's experience and success rate with similar masking challenges. Improper masking leads to costly rework or scrapped parts.

What impact does part geometry have on coating thickness uniformity, especially with processes like electroplating?

Part geometry significantly impacts coating thickness uniformity in electroplating due to the 'Faraday cage effect' and current density distribution. Areas with sharp edges, points, or protrusions tend to receive a thicker deposit, while recessed areas, deep holes, or inside corners often receive a thinner, or even no, deposit. This is less pronounced with electroless plating, which offers more uniform coverage. Always provide drawings with critical dimensions post-plating and discuss geometric challenges with your finisher to manage expectations or explore alternative processes.

What's Nadcap and why is it critical for certain metal finishing applications?

Nadcap (National Aerospace and Defense Contractors Accreditation Program) is a global industry-managed program for special processes like chemical processing, heat treating, and coatings. It goes beyond ISO 9001/AS9100 by specifically auditing the technical competence and adherence to stringent process controls required for these critical manufacturing steps. For aerospace, defense, and some medical device applications, Nadcap accreditation (e.g., AC7108 for chemical processing) is often a mandatory requirement to ensure the highest levels of quality, reliability, and traceability for life-critical components, significantly reducing supply chain risk.
