Fabrication Tolerances for Dimensional Variance in Sheet Metal and Machined Parts Overview Protocase takes great care to manufacture your electronic enclosures, parts, and components as accurately as possible.
general dimensional tolerances for sheet metal formed parts
Dimensional tolerances for parts that are formed with hard tooling after photochemical etching have to be determined on a part specific basis by the fabricator. Finally, dimensional tolerances for dropout parts are different than for parts that remain on the sheet.
