Faceplate lettering.

[moldmker]

Hello,
I'm involved in a reverse engineering project for 20 custom electronics enclosures.

The painted faceplates and buttons have black lettering/graphics which I need to replicate.

I have the artwork on file.

I need to explore different methods of applying the letters.

Searching web reveals laser printing/heat transfer method and laser/water decal.
Looks like the heat transfer method would allow me the closest duplication.

Many of you have much more experience in prototype panels than I do. Any other methods/comments?

Thanks,
moldmker

Hi:
Sometimes we anodize the panels (after machining), and then engrave (on the VMC)through the anodized coating (.003-.005 deep) a carbide endgraving tool.
It looks trick, and is reasonably fast.

moldmker-
Another option is to fill in the machined grooves with a colored epoxy to prevent oxidation. If you use a thin epoxy, and heat the part, it will flow nicely and come out almost flat with the top surface.

I should add this, the faceplates are .035" thick steel formed to slight arch.

I think I will be limited to a transfer process.

Keep the ideas coming.

Thanks,

edit: I just saw the other thread on inkjetting PCBs.
Had to chuckle, that was one option we joked about!

OK, so machine, then anodize, then engrave, fill with epoxy then roll form.

cheers

Oops, forget the anodizing on steel.
