Chicago Anodizing is a leading provider of barrel and bulk anodizing. This process is usually used in the screw and fastener industry, and is an inexpensive although functional alternative to location and rack anodizing. Barrel and bulk anodizing is a cost efficient alternative for certain customer's running high annual usage, but is not a fit for all projects. 

Please contact us directly for more information on this process and if it is a good fit for your anodizing requirements. 


Chicago Anodizing offers a number of mechanical finishes on aluminum surfaces prior to anodizing.  Our services include lathe polish, hand buffing, blasting (sand, glass and bead), brushing and time-saving. These processes are performed on a daily basis and Chicago Anodizing has the capabilities to handle high EAU for all of these offerings.


Chicago Anodizing uses a variety of masking techniques to ensure that any surface on any part can be free of anodizing if required.  We use plugs, glues, screws, paints, and tapes to complete total coverage of the surface area that has to remain in it's raw state.  Chicago Anodizing can develop and manufacture custom masking for programs that have a repeatable requirement and shorter lead times.
