How much build-up will I have?

Electroplating typically has build-up of less than 0.001″, but this can vary according to process parameters. Additional information relating to individual coating thickness can be found under the “Services” heading of each individual finish.

Surface treatments like chemical conversion coatings on aluminum, black oxide, and Dow #7 have no build-up.

Electroless plating such as electroless nickel has the ability to hold tolerances as close as 0.0002″.

Coating thickness of electrolytic processes like chrome and nickel plating are more difficult to control since they build up more on outside corners and edges (which are high current density areas) than on inside corners, recessed areas and center areas (which are low current density areas). If your tolerances are closer than 0.005″, it would be wise to contact us for advice.
