Our Chemical Processing department offers several services including multiple anodize type II and type III processes as well as a number of chem film services. Frontier Group has the capacity and expertise to accommodate small and large parts, those requiring masking (or not) and those requiring multiple colors. Our Chemical Processing operation is supported by 1,000 gallon anodize and 500 gallon other process tanks and a team of professionals who are experienced in working with complex parts. For size capabilities, please contact us for further details.

Additionally, Frontier Group is the only provider of TriPlex™ processing which employs a modified version of anodize type III and a three seal process. This process significantly enhances the durability and functionality of the hard anodize surface.
