Complete Surface Finishing

Overview

Made In America handles the full range of surface treatments in-house, so your parts ship complete without additional vendors or handoffs. Our finishing department supports aerospace and defense specifications across passivation, anodizing, plating, coating, sand blasting, tumbling and our proprietary sub-Ra 8 µin finishing process. Heat treat and NDT are coordinated with certified vendors and fully documented on every program. Every finish applied per customer specification with full documentation and inspection before parts ship.
  • Passivation per ASTM A967 and AMS 2700
  • Anodizing Type II and Type III hard coat
  • Chemical Film per MIL-DTL-5541
  • Silver, gold, and nickel plating
  • Painting per mil-spec and customer requirements
  • Proprietary sub-Ra 8 µin finishing process
  • Shot peen for fatigue life improvement
  • Heat treat and NDT coordination with certified vendors

Finishing at Made in America

Types

Complete surface treatment

  • Chemical and Conversion Coatings

    Passivation per ASTM A967 and AMS 2700 for stainless and high-alloy parts. Anodizing Type II and Type III hard coat for aluminum components. Chemical Film per MIL-DTL-5541. All processes documented and traceable to part serial number.

     

  • Plating

    Silver plating for electrical conductivity and corrosion resistance. Gold plating for high-reliability electrical contact applications. Nickel plating for wear resistance and dimensional build-up. Plating thickness controlled and verified per drawing requirements. Aerospace and defense plating specifications supported.

     

  • Painting and Specialty Coatings

    Painting per customer color, gloss, and mil-spec requirements. Teflon and dry film lubricant coatings. Shot peen for fatigue life improvement on aerospace parts. Heat treat and NDT coordination with certified vendors.

     

  • Mechanical Finishing

    Sand blasting for surface preparation and cosmetic finishing. Tumbling and vibratory deburring for edge break and surface prep. Ultrasonic cleaning for cleanliness-critical applications. Proprietary sub-Ra 8 µin process verified with profilometer measurement.

    Frequently asked questions

    • What finishing specifications do you support?

      We support passivation per ASTM A967 and AMS 2700, anodizing Type II and Type III, Chemical Film per MIL-DTL-5541, and painting per mil-spec and customer requirements. Aerospace and defense plating specifications are supported across silver, gold, and nickel.

    • Do you perform finishing in-house?

      Yes. Passivation, anodizing, plating, painting, coating, sand blasting, tumbling, and our sub-Ra 8 µin finishing process are all performed in-house. Heat treat and NDT are coordinated with certified vendors.

    • What is your sub-Ra 8 µin finishing process?

      Our proprietary finishing process achieves surface roughness below Ra 8 µin, verified with profilometer measurement. It is used on semiconductor equipment components, precision mating surfaces, and other applications requiring ultra-smooth finishes.

    • Do you provide traceability for finishing operations?

      Yes. All finishing processes are documented and traceable to part serial number. Full documentation is provided with every shipment.
