Cosmetic Finishes

Surface finishes serve dual roles, either functional or aesthetic. When they accomplish both, they are termed cosmetic finishes, ideal for enhancing the appearance of cosmetic parts. Ensuring flawless cosmetic part production involves taking extra precautions to minimize imperfections such as hang marks and tool-induced scratches.


Primary machining marks will still be visible.

Cosmetic On Request

Finishes can be either cosmetic or non-cosmetic as per request.

Cosmetic By Default

These finishes will always serve a cosmetic function.

Defining an A and a B side

Surface finishing processes can introduce aesthetic imperfections on your parts, such as hang marks in the case of anodizing. To maintain a pristine appearance in critical areas, consider defining an A-side and B-side in your design:


This represents the most visually significant surface, typically the one seen by users.


This refers to the less critical surface, usually hidden from view after assembly.

We guarantee defect-free production for the primary A-side of your part. Meanwhile, minor defects like hang marks may be present on secondary B-side surfaces. Rest assured, both A-side and B-side surfaces will be free of scratches, stains, and blemishes.
