CAD Data – HOW TO SUPPLY YOUR DATA
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.
|Metal Family||Thickness range||Maximum Sheet Size|
|Steel & Stainless Steels||0.005mm – 1.5mm||600mm x 1500mm|
|Nickel & Nickel Alloys||0.01mm – 1.5mm||600mm x 1500mm|
|Copper & Copper Alloys||0.01mm – 2.0mm||600mm x 1500mm|
|Aluminium Alloys||0.025mm – 2.5mm||600mm x 1500mm|
|Titanium & Titanium Alloys||0.01mm – 1.0mm||300mm x 500mm|
