When creating an in-filled text engraving on a powder coated panel, Front Panel Designer allows you the option to "Mill afterwards". This isn't an option on anodized panels because the anodizing is done first, but I'm curious about how it affects the result on a powder coated panel. Even if the difference is subtle, why would I choose one over the other?
It may not matter, but in my particular case I'm planning to use text with white in-fill on a black panel.

We recommend to have all engravings done after powder-coating when infill of the engravings is required. This way, the engravings won't be already covered with paint from the powder-coating process when we apply the infill paint (especially critical when having small engravings.) The result will look more defined and higher in quality.
However, engraving after powder-coating requires a second setup on our milling machines and is therefore higher in cost.
We give you more control over the cost of the panel by allowing you to choose when certain objects should be cut or engraved. The default setting for engravings is always "mill afterwards".
I only know one good example for having engravings cut before powder-coating. This would be a serial number that shouldn't jump out too much with no infill paint somewhere on the bottom of the panel.
I hope that explains the difference.

Thanks for your prompt and clear answer! I'll definitely keep the default, mill afterwards.

I want to cut a 4 x 20mm slot, 3mm deep, in a 4mm thick anodized panel (which is 60 x 85mm). Into this slot I want to slide (and later bond) a 4 x 20 x135mm anodized panel, so that this thin panel will be perpendicular to the 60x85mm panel.
My question concerns the tolerances of the slot and 4mm stock thickness. I was planning on making the 4x20mm slot 4.06 x 42.0 mm (with 0 radius corners); should the 4.06mm width be sufficient for the 4mm thick stock?

4.06mm is a little tight. I usually recommend 0.2mm tolerance for a not to loose fit. A snug fit should have 0.1mm tolerance (in your case a slot of 4.1mm width.)
We can make sure that the parts fit. Just leave us a note in the fpd file (panel properties) or in the order program. The additional check in our QC department is complimentary.

Hi I am wondering if you will anodize a raw aluminum panel I send in for milling and engraving. If so how do I compute the charge...or can you just send me an additional bill.
Also, the raw aluminum currently has a lightly brushed finish. I don't care if the brushed aspect of it will be lost, just wanted to mention in case it can't be anodized if it's already brushed.

Unfortunately we do not have any anodizing capabilities at our shop. All our materials are pre-anodized and we can't anodized customer supplied material.
We offer in-house powder-coating as additional finish option. Maybe this is something you are interested in as well. Let me know if you would like us to send you some samples with powder-coated finishes.

Thanks Diane, sorry for the slow response.
I ended up getting the parts anodized locally. I'll be sending one of them in for machining and engraving.
I'll keep powder coating in mind for the future also,

I have a panel (steel) which has a 2.5mm lip on the top and bottom running the length of the panel. Is it possible to do any engraving on this panel, or does the lip keep the tools from correctly reaching the panels? (as in: do I really need to use a flat panel?)
Posted By: bhjazz on May 07, 2013 05:24AM Category: Production
Look at this thread. Panels with lips are no problem at all. We can mill on almost any part as long as it can be held on our machines.
However, steel is a problem. The spindles of our machines can only handle non-ferrous material like aluminum, brass, copper, etc.

Thanks for the information, Diane. I appreciate it. I'll get with my client and suggest aluminum as a replacement.
Have a great day!

Doing an amplifier chassis out of 2.5mm anodized/chromated stock and want to make it a "U" shaped piece with bends for the front and back panels. I know chromium is brittle - how about the coating you use?
Looking at a rounded 90 at the rear and a sloped panel up front.
Also wondering about milling the inside thickness down at the bend points? I've done it with a carbide flat bit in a router with many many passes just shaving the metal, but wondering if there's a better way. I figure around a quarter inch wide and half the thickness the full width of the chassis plate should make it possible to clamp the panel and bend it by hand.

The chromated finish is always on the back of the part (if not requested otherwise.) The chromated side is conductive, making it suitable for EMC applications.
I don't see a problem with bending it since it is on the back. However, the anodization on the front will crack most likely. We can send you some material samples if you like.
And there is always the possibility of machining customer supplied material. You can buy off-the-shelf u-shaped parts from many suppliers for reasonable money and have us do the machining. Just a thought.

I have 2 complimentary L-shaped parts. Is it allowable to submit them as a single "panel" separated by a cut? If so is the correct way of doing this using elongated shapes made with the hole tool?
Posted By: ecurtz on Mar 18, 2013 07:31PM Category: Production
here is a link to an old post. It has combined parts as well.
Just give the L-shaped parts enough stability to not collapse during milling. I recommend a short "connector" of 10mm length all 120mm along the perimeter.
