How To Supply Your Files

Please ensure all lines are continuous (no breaks) and all dimensions on nominal.
For QA inspection measurement we require a drawing with critical features identified.
Please provide a scale line on data.
Please clearly identify any ½ etched features and which side of part, detail is required.

more than 2000 different metal types

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.

Materials, thicknesses & sizes

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

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.
