| Finishes Option | Finishes Description | Finishes Color | Finishes Purpose |
|---|---|---|---|
| Default Surface | This is the surface finish that results directly from the machining process without any post-processing. It may have visible tool marks and is not typically very smooth. | Various (depends on material) | Basic finish, cost-effective |
| As machined | Parts are machined and deburred, sharp edges are chamfered. Visible machining marks, light surface scratches. | Various (depends on material) | Machining Decorative Patterns |
| Bead Blasting | A cold working process to improve fatigue life by bombarding the surface with spherical media. | None (textured surface) | Improve fatigue life, enhance surface strength |
| Sand Blasting | A surface treatment process using compressed air to propel abrasive material against a surface for cleaning or roughening. | None (textured surface) | Clean surface, increase roughness |
| Electrophoretic | A coating technology that applies an organic or inorganic coating to a metal surface through an electrochemical process. | Various (including black white, red, green, champagne, blue) | Provide decorative effect, improve corrosion resistance |
| Electroplating | Electrochemical deposition of a metal coating onto the surface of a part to improve appearance and resistance to corrosion. | Various (depends on plating material) | Improve appearance, increase corrosion resistance |
| Electropolishing | Electrochemical polishing to smooth the surface, improving brightness and reducing roughness. | Mirror finish | Improve smoothness, enhance brightness |
| Chrome Plating | Applying a layer of chromium to a metal part to increase wear and corrosion resistance. | Silver | Improve wear and corrosion resistance |
| Nickel Plating | Applying a layer of nickel to a metal part to improve corrosion resistance and appearance. | Silver | Improve corrosion resistance, enhance appearance |
| Gold Plating | Applying a layer of gold to a metal part to improve conductivity, corrosion resistance, and provide decorative effects. | Gold | Improve conductivity, enhance corrosion resistance, provide decorative effect |
| Silver Plating | Applying a layer of silver to a metal part to improve conductivity and corrosion resistance. | Silver | Improve conductivity, enhance corrosion resistance |
| Tin Plating | Applying a layer of tin to a metal part, often used to prevent oxidation and improve solderability. | Silver | Prevent oxidation, improve solderability |
| Zinc Plating | Applying a layer of zinc to a metal part to improve corrosion resistance. | Silver | Improve corrosion resistance |
| Laser Marking | Using a laser to mark the metal surface, providing permanent identification. | Various (depends on material) | Provide permanent identification |
| Cleaning | Using various methods to clean the metal surface, removing contaminants and impurities. | None (depends on material) | Remove contaminants, improve surface quality |
