Title: Powder coated aluminium enclosure? Etch able with Banggood 2500mW?
Post by: Bigwan on May 04, 2016, 09:34:35 AM
Hope this is in the right place! I'm really interested in the banggood 2500mW uv etcher, but I was wondering if anyone here had ever etched any powder coated aluminium with one of these machines? Is it possible with UV?

Maybe...someone here has etched aluminum bottle openers...give it a try and let us know your results...

I did find a couple of "gotchas" when I tested the coated (anodized?) aluminum bottle openers.

Some colors did not etch at all.

Polished Silver: so reflective no heat from laser absorbed?
Dark Blue: no idea why; blue laser on blue paint won't absorb the laser's heat?

These colors did etch beautifully @ power 255 on 5.5W (but I did a test at a power of 100 and it worked just as well):

Black
Red
Orange
Green

I'd noticed people here had managed anodised aluminium etching, but it's specifically powder coating etching I'm interested in. I'd like to etch artwork and lettering into off the shelf Hammond brand powder coated enclosures such as the 1590 series: http://www.hammondmfg.com/dwg_SBVer.htm for guitar effects boxes.

May have to suck it and see!

Scary to try something like that. Someone asked me if I could engrave their MacBook. he**. No.

Not sure I understand... Sure you might screw up an enclosure or 2 proving out that it works (or not), but they're not stupid expensive.

You realise I'm building these effects myself, not playing with somebody's prize possession, right?

Yeah, but I guess my point is that it unnerves me to engrave anything "good". There's no eraser. If it's for business, you gotta do what you gotta do.

Considering the accepted etching norm in boutique pedal land is transferring laser printer toner onto a bare aluminium enclosure as a chemical resist and etching the exposed areas in a ferric chloride solution I think this is a nice,  quick,  clean alternative if it works!

Not answering the OPs questions but it might be helpful to know that I did this test piece on metallic foil coated laminate with 2.5W laser.

I can't be certain, but from that link, the finish does look similar to the openers I played around with. Pic attached.

@Bigwan, your profile doesn't say where you are but if you want to send me a lid from one of those boxes I would be glad to test it for you, or perhaps there's someone close to you that would work with you to check it out?

I'm in Northern Ireland where most people are naturally suspicious of "new"  technology...  I might take you up on that Zak!

There are many users in the UK, which would be cheaper for postage but if you don't have any luck PM me and I will give you my address (USA).

Any particular reason for the UV laser? I'm just curious what made you decide to go that route as apposed to the 450nm laser version.

I did play with a powder coated bar the other day it did engrave but not all the way through.
This was before I started recording times and speed.

Have you found your answer? I own a powdercoating business and am going to try to etch after coating.

Yes I have etched coated aluminum. A LED flashlight body. Step at 300 and power 100%

I have 3 Hammond BB stomp boxes. I am making my dad a guitar pedal. I was wondering the same thing. I will throw a logo on one tomorrow (on the bottom of it doesn't work) and report back

Reporting back. I tried engraving on a Hammond BB box and it did not make even a small mark

Settings I used:
T2 Laser
Full power
400 speed
0.1 resolution
2W laser

I "etched" a Altoids container.  The darker colors on the container etched better than the lighter colors.
