Post-Processing
USA Industrials is your solutions provider for post-processed parts
Overview
USA Industrials offers extensive post-processing capabilities. We have the ability to apply a broad range of platings and coatings that enhance performance properties on fasteners, hardware, fittings and more. Our in-house ISO Class 7 (10,000) clean room is used to manufacture and sterilize products for high-purity applications.
Clean Room
Clean Room: Parts are cleaned and bagged in an ISO Class 7 (10,000) clean room to remove dirt, bacteria, and surface particles.
Platings & Coatings
Zinc: Most common plating. Low cost and good corrosion resistance in environments not subject to excessive moisture.
Cadmium: Commonly used in marine and aviation applications. Offers superior corrosion resistance.
Chromate: A secondary dipping process after zinc/cadmium plating. Typically used to add color for aesthetic or identification purposes.
Iridite: A secondary coating process after zinc/cadmium plating. Typically used to add color and additional corrosion protection.
Black Oxide: Conversion coating that does not add to part thickness. Usually combined with oil dip, which serves as a rust inhibitor and lubricant.
Black Phosphate: Similar to Black Oxide. Conversion coating, which is usually combined with an oil dip.
Nickel: Offers very good corrosion resistance, with a silver color that provides a more decorative appearance.
Tin: Commonly used in the food handling industry. Offers strong corrosion resistance against organic acids and improved lubricity.
Silver: Enhances electrical conductivity and resists breakdown under extreme pressure and/or heat.
Galvanizing (Hot Dip Zinc): Applies a thick coating of zinc to serve as a corrosion protectant in harsh environments.
Passivation: Most commonly used on stainless steel materials. Parts are dipped in nitric acid, which removes surface imperfections and produces a slight film for a bright and corrosion-resistant finish.
Anodizing: Most commonly used on aluminum materials. Parts are dipped in acid, which oxidizes the material and leaves a hard and corrosion-resistant finish. Can be color-dipped after anodizing.
Wet Paint & Powder Coating
Wet Paint: Coating is applied as a liquid via an evaporating solvent.
Powder Coating: Coating is applied as a free-flowing, dry powder. Powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
