[EE] Prototype membranes / decals

[K S]

Hi list.

For PCBs we have fantastic (quick / cheap / quality) services such as
allpcb.com.

Does anyone know of a similar service for membranes / decals? And also
possibly for machined plastic or metal parts? Hopefully with a simple web
interface for specifying and uploading designs and getting an immediate
quote, and with nicely priced worldwide delivery?

TIA.

[Jim]

Try Protomold for the plastic parts

Regards,

Jim

I have not used them, but I've seen ads for
https://www.frontpanelexpress.com/ that look interesting.

Thank you. Yes, I do know of this operation but they do metal panels
(and seemingly quite reasonably priced!) not the membrane / polycarb
decals.

Protocase is very good for enclosures.

Thanks Jim and Sean. I've given them a go - I'll see what comes back.

I'd never been to the allpcb.com site, so I had a look around. They
actually have an option for membrane switches and panel overlays. No
idea how it compares costwise though.

Protocase is very good for enclosures. They will do panels, too. Emphasis
is on speed so the price is a bit higher than some other places might be
but I've done 4 unique enclosures and one small production run (abt qty 50)
panel wirh them.

Wow - I had no idea! This is actually exactly what I was after! Thank you!

A do-it-yourself method for label/decal/graphic overlay...
Flip/mirror the image, laser print onto transparency/acetate. Spray paint white or other background colour, use light coats and drying between coats to avoid dissolving image. Adhere with double sided tape.
Relatively quick and cheap. Result is a glossy and hard wearing surface, as image is sandwiched between transparency and paint. As waterproof as the adhesive is. Cut with care to avoid delamination. YMMV, experiment to perfect.

I'm trying not to do it myself, for the same reason I abandoned making
my own PCBs - time taken, quality, messiness etc. But I must say your
example looks mighty fine!

I have a decal printer that can do this... it can print on .005" or
.010" polycarbonate (so it's stiff though can bend) and it uses foils,
so it can print metallic colors also.
The bottom of this page has examples on what it can do...
http://www.gerberprinters.com/

Mine's temporarily down, but you can find any sign shop that has the
same printer (Gerber Edge) and they can do it for you. And they can do
it with an adhesive backing.
If you can't find a place that has one, you can ask at signs101.com

Cheers,
-Neil.

A similar method that I used to use with good results:
Label appearance was as good as many commercial labels, and the method is
quick, easy and relatively low cost (choose any three).

- Print onto media of choice - white or coloured paper or card.
- Add a layer of clear "coverseal" or similar adhesive faced plastic-
intended for covering book covers.
- Cut label to size.
- Attach with adhesive of choice. PVA worked well in my application, but
double sided tape or other could be used depending on target substrate.
