Surface Finish Options
Protecting and Optimizing
Your Precision Parts
Newly formed cnc parts require specific post-processing to boost durability, improve surface aesthetics, and allow for color variation. We offer 13 unique surface treatments designed for optimal part outcomes.
As Machined
Leaves parts with their natural, economic finish directly from machining.
Brushed Finishing
Creates a uniform, textured matte appearance for enhanced aesthetics.
Sand Blasting
Produces a clean, diffuse matte surface, ideal for improved paint adhesion.
Anodizing Type II
Forms a decorative, corrosion-resistant, and dyeable oxide layer on aluminum.
Anodizing Type III
Builds a harder, thicker, and more wear-resistant protective coating than Type II.
Heat Treatment
Alters metal properties like hardness and strength through controlled heating and cooling.
Polishing
Achieves a smooth, highly reflective surface, eliminating imperfections for visual appeal.
Electro Plating
Deposits a thin metal layer to boost corrosion resistance, conductivity, or visual appeal.
Painting
Applies a colored, protective coating, customizable in various textures and finishes.
Passivation
Enhances stainless steel’s corrosion resistance by forming a stable, protective oxide film.
Electrophoresis
Ensures even and highly adherent paint coverage, especially on complex geometries.
Alodine Finish
Provides corrosion protection and electrical conductivity, often as a paint primer for aluminum.
Teflon Coating
Offers excellent non-stick, low-friction, and high-temperature resistance properties.
Gold Plating
Delivers superior conductivity and oxidation resistance, commonly for electronic applications.
SPI Surface
Defines precise mold textures, from mirror-like to coarse, for injection molded parts.
Vibrant & Durable Aluminum Anodizing
Permanent color and durable protection for aluminum that enhances beauty and is built to last.
