Basic Finishes
Standard or minimal surface treatments used to clean, deburr, or prepare parts for further precision processing.
Mechanical Polishing
Uses fine abrasive compounds to reduce surface roughness, producing a smooth, highly reflective or mirror-like appearance.
Sanding & Deburring
Uses abrasives to remove surface blemishes, smooth sharp edges, and prepare components for subsequent coatings.
As-Machined
Standard surface roughness (3.2 µm / 125 µin Ra). Parts are cleaned and deburred without additional surface finishing.
Surface Textures
Abrasive blasting processes that remove surface contaminants and create uniform matte or satin textured finishes.
Sand Blasting
Uses compressed air to propel abrasive media, effectively removing scale, rust, and surface contaminants with light texture.
Bead Blasting
Shoots fine glass beads at high pressure to clean parts and yield a smooth, glare-free matte satin texture without changing tolerances.
Coatings & Painting
Applies protective or decorative layers over components to enhance durability, corrosion resistance, and aesthetic appeal.
Spray Painting
Applies liquid paint coats over part surfaces for aesthetic color customization, branding logos, or functional surface protection.
Powder Coating
Electrostatically applies dry powder and heat-cures it to form a durable, uniform, colorful, and UV-resistant protective layer.
Cataphoretic Coating (E-Coating)
Uses electrical current in a paint bath to deposit a uniform, highly corrosion-resistant organic coating over conductive metal parts.
Electroplating & Metallic Coatings
Deposits thin metallic layers via electrolysis to prevent rusting, improve conductivity, and elevate visual appearance.
Electroplating
Electrochemical process depositing thin protective metal films (like chrome, gold, or silver) onto conductive part surfaces.
Zinc Plating (Galvanizing)
Applies a sacrificial zinc coating to protect iron and steel components from atmospheric corrosion and sacrificial rusting.
Nickel Plating
Deposits a thin, hard nickel layer to provide superior wear resistance, chemical protection, and a bright metallic luster.
Chemical Treatments
Alters metal surface chemistry through immersion to maximize corrosion resistance, surface hardness, and paint adhesion.
Natural Anodizing (Clear)
Creates a protective oxide layer without added dye, retaining the aluminum’s natural metallic appearance while improving corrosion resistance. Suitable for housings, brackets, and precision components.
Black Anodizing
Combines a protective anodized layer with black dye for a clean, professional appearance and improved corrosion resistance. Available with matte or satin textures depending on surface preparation.
Color Anodizing
Adds color to anodized aluminum while preserving its surface texture and metallic character. Suitable for decorative components, product identification, and custom assemblies.
Hard Anodizing (Type III)
Produces a thicker, harder oxide layer to improve wear resistance and surface durability. Suitable for sliding components, guides, and parts exposed to repeated friction.
Passivation (ASTM A967)
Chemical acid bath treatment removing free iron contaminants from stainless steel surfaces, creating a corrosion-resistant passive film.
Chromate Conversion (Chem Film)
Chemical conversion coating for aluminum/magnesium providing corrosion resistance while preserving low electrical contact resistance.
