Electrochemical Etching
Etching Stencils
The stencil is what actually shapes your mark: current only reaches the part where the stencil's image area is open, so stencil choice determines everything from line fidelity to how deep you can etch. We process every stencil photographically in-house on a tough lacquer base built to hold up for thousands of marks.
How to Choose
Etching Stencils
Depth is the first decision. Running an automatic marking machine, or a rolling application like marking needles, changes the calculus: Insert Stencils are reinforced with a heavy-duty flexible frame and polarized locating holes so they re-register consistently onto your fixture, run after run. If your application is sheet-metal forming analysis rather than part identification, you’ll want to look for Grid Marking Stencils.
Our Dura-Fab (DF)
construction, on a synthetic woven fiber base, is built for stencil designs with features at least 3/32" deep
Dura-Fab Fine (DFF)
uses a closer weave and is a good fit if your artwork is finer or more detailed.
Dura-Fab Deep Etch (DFDE)
is our most commonly used stencil for deep etching jobs and doubles as a general-purpose stencil when needed.
Dura-Fab Fine Deep Etch (DFFDE)
combines fine detail with deep etch, ideal for scales, lines, or grid patterns.
