The GM approval certifies that Arlington Plating Co. is highly qualified to anodize exterior aluminum parts that address both Class A and Class B alkaline pH requirements, as well as decorative interior trim applications. Recently completed in January, the automated line produces MIL-A-8625 Type II (sulfuric) anodizing with high pH sealants, organic die coloring and electro color capabilities. The line offers bright dip and satin finish applications.

The GM team’s extensive review included an audit of the 44 process tanks that comprise the anodizing line, as well as best practices and standard operating procedures performed by Arlington Plating Company. GM noted that the installation of the automated line, representing over a $2 million investment, factored into granting GMW14665 approval so quickly.
