I’m new to powder coating and have been trying some things and having some problems.

Background:
I built my own oven. I haven’t done a temp. calibration yet.
I have the Redline 250 gun.
I’ve added a ground wire from my spray rack to a ground rod outside my garage.

Successes:
Black on bare steel – looks great
Lollypop Purple on bare steel and bare aluminum – looks great

Failures:

1. Extreme chrome on bare steel and bare aluminum – color separates in places – See picture. Do I need thicker powder, lower temp, longer cook?
My oven has an old house oven temp controller – the powder says 392 for 30 – 60 minutes. I set the dial at very slightly under 400 and cooked for 35 minutes.

2. Illusion Amethyst and Illusion Aquamarine over black. I couldn’t get an even coat of powder to stick. Tried different settings on the gun, didn’t seem to matter

3. Lollypop Purple over Extreme chrome. Had the same problem with powder not sticking evenly. Tried with over Extreme chrome hot right out of curing oven – that’s the dark one. – seemed to get a more even coat of powder on, but then the chrome seemed to lift up and mix with the purple in the oven.
Tried it on Extreme Chrome cold. – very poor powder adherance and some lifting of the chrome into the purple in the oven as well. That’s the light colored one.

Hopefully the picture helps explain my situation. Please advise to what things I should do to correct my problems.

Thank you so much.

Candy Apple Red

admin — Mon, 28 Sep 2009 09:01:31 +0000

Good evening folks. I am new to anodizing, but I have been anodizing sucessfully for the last few weeks. I have a customer looking for a similar color to candy apple red. I have Red Borderex (Spelling), but it is still too light. Can someone share any tips via message boards here or perhaps via pm. I have the color wheel, but it is only so useful in this scenario cause color on paper doesn’t look like color on aluminum.

Thanks!

What am i doing wrong here?

admin — Wed, 23 Sep 2009 20:42:30 +0000

What is going on here? I am still getting a streak in the one piece. The other piece is just dulling. I put both of these pieces in while they were a mirror finish. After i took them out of the ano bath they were dull. I dried them both off and i could wipe off a little of the dull color and i got a chalky film on my hand. Could it be in the water. The water is very clear. I just used soap and water, then the degreaser for about 3 minutes, i skipped the desmut this time and still the same results.:confused:>:(

Blotchy overdye

admin — Thu, 17 Sep 2009 20:05:49 +0000

A lot of things were working fine been hinky lately. ???

Been working with a lot of pieces that I realize are cut from the same alloy of sheet. My process has been

Cut (plasma cut)
Shape + deburr
Polish
Ano
Dye
(Redye)
Seal in nickel acetate

When they’re dyed the first time, they look beautiful, uniform, perfect. When they’re masked or acidwashed, though, the first color is fine – but the second becomes blotchy, and more so with every bleach/sulfuric dip + redye. Eventually with each treatment it stops dying at all; usually by the third bleach/acid/redye it’ll take only the lightest shade of the third color, in blotches.

Here is a piece that was dyed yellow, masked in parts, then redyed brown. The other was dyed blue, masked, dyed violet, masked, and dyed green (this is the backside, the flip with the masking was more uniform in green but several shades lighter -???). The effect could be desirable but is NOT what I’m looking for here.

Many thanks..

Two same alloy pieces..different results

admin — Wed, 16 Sep 2009 07:55:45 +0000

Thanks to recent improvements, most things are running better in my anodizing setup. But this weird problem keeps occurring.

Two of the same pieces that need deox/desmut connected together here. Both were anodized (badly, see my dozen other recent threads), stripped in lye, rinsed, deox/desmut, then reanodized. One comes out fine, or fine-ish. The other is pitted and when it dries, the pits become white bumps.

Two pieces of the same alloy, under same treatment and anoed in the same run, anodized at different colors, one dark grey, the other less so. Both pitted unacceptably and took dye differently, neither very well.

One was anodized more often than the other, this was one piece’s third run. But both were prepped the same way. I guess matching pieces must always be prepped, processed (and reprocessed) in lockstep, or both thrown out.

Thoughts?

New with questions

admin — Sun, 13 Sep 2009 07:49:38 +0000

i am new and just got my tanks setup. I am a little confused at the 720 rule.
I have the 25amp constant current supply. What do i need to set the current at. The test pieces i am trying to anodize are flat pieces 1" x 3". can someone give an example on how to figure this and what to set my power supply at. i tried one piece but the dye was faint in color. Thanks for the help.

Types of Anodizing

admin — Fri, 11 Sep 2009 19:30:33 +0000

Chromic Anodizing
Utilizing a chromic acid electrolyte this form of anodizing yields the thinnest coatings, only .05 to .1 mils thick. Chromic anodizing is a good choice when a part is complex and difficult to rinse because chromic acid is less corrosive than sulfuric acid used in other anodizing methods. Chromic anodize also reduces the fatigue strength of the aluminum less than the other methods described.
Sulfuric Anodizing
This form of anodizing yields coatings under 1 mil thick. Although it offers mild abrasion resistance it is more durable than chromic anodize. Like most anodizes corrosion resistance is excellent. The most desirable feature of this form of anodizing would be the excellent results from dyeing yielding deep and rich colors.
Hardcoat Anodizing
Also using a sulfuric acid electrolyte, although at a lower temperature, hardcoat anodize’s claim to fame is wear resistance. This will produce a Rockwell C-scale rating of 60-70. This makes it an excellent candidate for many wear situations.

Color match help request!

admin — Tue, 08 Sep 2009 19:21:57 +0000

Hi guys! I have a client that want his s2000 valve cover coated as the same J’s Racing use for their covers. The color is called Candy Teal just like columbia coatings one, but don’t seems to be the same, and I’ll like your opinion!
this is the J’s racing valve cover as the client wants:

and this is the cc Candy Teal

The valve covers seems a lit more blueish. I know it could be a flash/lightning changes (I have multiple pics of the same job that looks a lot diff depending on the light), but I’ll like the opinion of some one that has used Columbia Candy Teal!

thanks for your time and have a great day!

note: sorry for the threatjacking its just easyer than redacting it all over again!
