Our Surface Finishing Details
Part surface finishing methods serve either functional or decorative objectives. Every technique comes with its own set of prerequisites including materials, color, texture, and cost. Here are the details for the finishing techniques we offer.
| Name | Description | Materials | Color | Texture | Price | Link |
|---|---|---|---|---|---|---|
| As-machined | Our standard finishing option, the “as machined” finish, achieves a surface roughness of 3.2 μm (126 microinches), effectively eliminating sharp edges and deburring parts smoothly. | All materials | n/a | Stain | $ | / |
| Bead Blasting | Bead blasting involves forcefully propelling, typically at high pressure, a stream of blast media against a surface to strip away unwanted coatings and cleanse the surface of impurities. | Aluminum, Steel, Stainless Steel, Brass, Copper | n/a | Matte | $ | / |
| Anodizing | Our anodizing process enhances the longevity of our parts by providing resistance to corrosion and wear. It also serves as an excellent surface preparation for painting and priming, while offering an aesthetically pleasing appearance. | Aluminum | Clear, black, grey, red, blue, gold | Smooth, matte finish | $$ | / |
| Electroplating | Electroplated coating protects the surface of parts from decay by resisting rust and other defects. This is achieved by using electric currents to deposit metal cations onto the parts’ surfaces. | Aluminum, steel, stainless steel | Gold, silver, nickel, copper, brass | Smooth, glossy finish | $$$ | / |
| Polishing | Polishing processes, varying from Ra 0.8 to Ra 0.1, employ abrasive materials to rub against the part’s surface, adjusting the level of shine to meet your specific needs, from less to more shiny. | All materials | n/a | Smooth, glossy finish | $$$$ | / |
| Powder Coating | By utilizing corona discharge, we ensure the powder coating adheres to the part, forming a layer that is more resistant to wear. This layer typically varies in thickness from 50 μm to 150 μm. | All metal materials | Custom | Glossy | $$$ | / |
| Brushing | Brushing is a surface finishing technique where abrasive belts are employed to create patterns or marks on the material’s surface, primarily for decorative reasons. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a | Satin | $$ | / |
| Painting | Painting entails applying a coat of paint to the part’s surface through spraying. Customers can select colors matched to their preferred Pantone number, with finishes available in matte, gloss, or metallic. | Aluminum, Stainless Steel, Steel | Custom | Gloss, semi-gloss, flat, metallic, textured | $$$ | / |
| Black Oxide | Painting involves the application of a paint layer to the surface of the part by spraying. Colors can be customized to match a specific Pantone color number chosen by the customer, and the available finishes include matte, gloss, and metallic. | Steel, Stainless Steel | Black | Smooth, matte | $$$ |
