Customized Standard Diecast Examples:

  • Diecast aluminum alloy that is rugged, yet easy to machine
  • Lap joint construction protects against dust and splashing water, as well as provides improved EMI/RFI shielding
  • Smooth surface with no sharp edges
  • Designed to meet IP54
  • Low side wall draft angle (2 degrees or less) for easy PC board mounting

Draft Angle:



  • Manufacturing tolerance for the stocked diecast aluminum enclosures we offer are noted in that tables above.
  • Our standard CNC machining tolerances is ±0.005” (0.127mm). As a result, all cutouts and machined features on a single face will be ±0.005”. relative to one another only.
  • Our standard CNC machining tolerance and the manufacturing tolerance of the diecast aluminum enclosure will stack. For example, for a diecast aluminum enclosure being customized, the actual tolerance on your cutouts could be ±0.025” (±0.020” + ±0.005”), depending on how the part is set up in our machine.
  • If you require a tighter tolerance from a certain location, please be sure to relay this information to your Protocase Account Manager when requesting a quote so that our Engineering & Design Services team can be made aware.
  • For example, if you require a tolerance of ±0.005 from the right edge of a face, the “leftover” tolerance would be applied relative to the left side of the face, which would mean the tolerance would be ±0.025” from the left side.
  • Note: Leftover tolerances can only be applied to one of two perpendicularly opposed edges on a face. (For example, this tight tolerance rule could be applied to the top and right edge, but not the left and right edges).
  • The way in which we choose what edge to reference is arbitrary. If you need to have a tolerance tighter than ±0.025” from any edge, please let your Protocase Account Manager know.
