Automatic Anodizing is a provider of Type III Hard Coat Anodizing services, specializing in industrial-grade protective coatings. By combining quality customer service with strong communication, we are able to follow custom needs to the letter while keeping pace with necessary turnaround times. In addition, our specialization in precision coating of small parts sets them apart from lesser competitors.

This Type III hard coat anodization is a Mil-spec compliant product, providing hardness up to 70 Rockwell on any aluminum substrate part. Automatic Anodizing uses an electro-chemical approach, with anodization taking place within tanks filled with Type III sulfuric acid. Coatings, which can be clear or black, may be up to .003″ thick, and can, cover areas up to 12 sq. ft. The final result is a highly protective hard coat that leaves the aluminum substrate well protected.

Additional services, including PTFE coating, grit blasting, and custom marking can be added to any Type III hard coat order. Automatic Anodizing welcomes orders of any size, from one-offs to large production runs. All processing takes place within an ISO 9001:2008 certified environment.
