Read MoreCritical Holes Out of Tolerance
The aerospace detail parts we send out for anodizing are often coated with a chemical film (Alodine) to aid in the application of masking. When the Alodine is dissolved before anodizing, the precise diameters of holes are often eroded oversize, which will scrap the part in many cases. What is the best way to specify on a drawing or purchase order that such erosion cannot be tolerated? Should a certain masking technique be specified? Are there certain processes that should be forbidden?

Any suggestions as to what the problem might be?
