Lead Times

Anodizing is completed off-site via a third-party supplier. This means there is additional lead time and a minimum lot charge for this service.


Graphics can be applied on all of our anodizing colors via digital print and silk-screening. Please contact your account manager to discuss other anodizing options.

Other Constraints and Limitations

• For welded parts that have been anodized, there will be a noticeable difference in color between the part and where it has been welded.

• Our anodizing suppliers cannot guarantee color uniformity, especially for larger parts or parts in larger unit quantities.

• For consistency in anodizing color, we recommend small-sized parts in small volumes. Some parts may have racking marks.
