CAD Data – HOW TO SUPPLY YOUR DATA


We can accept the following file formats:

Please supply to our Sales team by email.

  • DWG

  • IGES

  • DXF

  • Gerber

  • Step

  • or fully dimensioned drawing

How to supply your files

  • Please ensure all lines are continuous (no breaks) and all dimensions on nominal.

  • Please provide a scale line on data.

  • For QA inspection measurement we require a drawing with critical features identified.

  • Please clearly identify any ½ etched features and which side of part, detail is required.

MATERIALS, THICKNESSES & SIZES


  • Advanced Chemical Etching (ACE) processes more than 2000 different metal types in a wide range of sheets sizes, thicknesses, finishes and grades.

  • We can also etch special metals on request and work with customer-supplied material. All dimensions & tolerances are a guide only, all subject to metal type, part size, feature and volumes.

Corner Radii


With photo etching, the smallest inside and outside corner radius achievable is directly proportional to the thickness of the selected metal being processed.
  • A - Outside corner radius – minimum of 75% material thickness

  • B - Inside corner radius – minimum of 100% material thickness

Etching Principle Cusp and Feature Sizes


During etching, the front and back of the metal is attacked simultaneously resulting in an etch cusp, this is usually 10-30% of material thickness.

Advanced Chemical Etching (ACE) controls the process to produce a range of profiles.
