BRIGHT DIP ANODIZING
Chicago Anodizing is one of the few anodizers in the country that offers Bright Dip Anodizing. Bright Dip is a chemical pre-treatment done to aluminum parts just prior to anodizing that enhances the sheen of the metal and gives it a polished appearance. Our proprietary Bright Dip process is done upon customer request, prior to Type II or Type III anodizing, and parts can be dyed color to specification.
TYPE III, CLASS 1 & 2 ANODIZING
MIL-A-8625 TYPE III, Class 1 & Class 2 (dyed) Anodizing, also knows as Hardcoat Anodizing, is a process that utilizes sulfuric acid with low temperatures and high voltage to create a very hard surface area on the aluminum pieces. Hardcoat is generally used for parts in need of abrasion and wear resistance. Chicago Anodizing supplies Hardcoat for a collection of industries worldwide, including automotive, firearm, nuclear and aerospace.
CAC can work around any customer requirements to add coating thickness to a customer's preferred specification. Chicago Anodizing understands the critical nature of the Hardcoating process, and is equip to handle parts of all shapes and sizes for Type III.
