Chiggo is your one-stop machine shop for custom manufacturing and surface finishing. Our wide range of surface finishing services takes your project that final step to perfection. Quality and aesthetics, tailored for you.
Surface finishing can be for either functional or aesthetic purposes. Each technique matches specific materials, offering unique colors and characteristics. Some finishes can be used individually, while others can be combined. Below is a quick cheat sheet of the surface finishes we offer.

Cosmetic finishes refer to surface treatments applied primarily for aesthetic enhancement, although they also can offer functional benefits such as increased durability, corrosion resistance, and improved surface hardness. These finishes are designed to enhance a product's visual appeal by adding various colors, textures, or gloss levels.
These finishes are used primarily for protection or performance, not for aesthetic purposes, and generally do not offer a cosmetic option
These finishes are primarily applied for functional purposes but can be enhanced or altered to also serve aesthetic purposes if requested
These finishes are inherently decorative and are primarily used to improve the visual appeal of an item
For Better Surface Finishing Results, It Is Essential to Specify the Following Key Points on Drawings
Specify the dimensional tolerances that must be maintained after surface treatment to ensure that the processing does not adversely affect the assembly or functionality of the part.
