Powder coating aluminum wheels
Вставка

- Sorry about the noise! This is why I don't record in the shop too often. In this video we break up the monotony a bit with something a little different. This should give you guys a good overview of what powder coating is, and how it is applied. These mopar aluminum turbine wheels were far from perfect, and basically headed for the scrap yard, and after a lot of cleaning, blasting and outgassing, they were ready to coat. We used 4 different powders for this 2 tone look . The outside of the barrels was coated in black epoxy, the face was coated with alien silver, then with a clear, and the rest of the wheel was coated with a wrinkle black. These were the 2nd set, 2 other wheels have already been done.

Great job !!!!!! Thanks for sharing.
Thanks! You bet!
looks great, thanks for sharing.
This way awesome to watch great job wheels look badass
Really awesome work!
Thanks!
Great video 👍🏻
Thank you sir!
Those are American Racing hurricane turbine wheels.
Chrysler bought those in bulk to install on the pickups and Ramchargers.
Nice!!
I didnt know Keifer sutherland was doing powder coating these days
Ha ha ha!! He does sound like Keifer Sutherland!!!
Awesome work, would you tell me the temperature you are setting for the heating process ? Cause every rims manufacturer recommends not to expose aluminum to more than 150°C
These were cured in the oven at 330f (165c) but you could cure them at 150c with a little longer cure time.
@@vintagemixersandmore1666 great! Thanx for the reply! Sorry to keep on bothering... For how long?
@@ariellovera8550 Last coat on these was about 30 minutes once the parts were heated to 330, but these had 4 coats in some places. Go longer if your unsure. Black and darker colors are very hard to overcure unless you forget about them and leave town lol, but colors like white and clear can turn darker if overcured but it does take a while, so you can leave the parts in longer if unsure, especially at lower temps for aluminum or zinc parts.
@@vintagemixersandmore1666 awesome! Lots of info to consider! Thanks so much dude! We will be doing some tests on a couple VW Golf GTI rims soon... 😜
@@ariellovera8550 Awesome, good luck!! One more thing, if you are shooting any type of metallic like chrome, you will need to fully cure it before you apply the clear, or it will turn gray. Try practicing on something scrap as well if you are using a lower temperature to cure, and test it to make sure it is fully cured so you know the time you will need to leave it in the oven. Time starts when the part reaches curing temperature, not the oven, and thick parts like wheels take longer to reach cure temp. An IR temp gun is a godsend when first starting out!
Hi there. New subscriber here. I am totally less then novice with all this powder coating. Great job by the way. I love how old wheels can be recycled and revamped with a little know how and some time. I had 1 question. It pertains to steel and aluminum. One is electrically charged (the steel) so with aluminum you don't need a charge or does that come from the powder? Might seem like a dumb question but just trying to understand all of this. I'd like to get a little setup and do some old rims I have. Thank you.
So it don’t hurt the first grey coat to go through 3 cure cycles?
What is the apoxy? I’m new to this and it’s the first time I’ve heard of it and it looks like u just used as a measure to something on the inside why not use on the whole wheel? Or use it as a base? What is apoxy and what’s it for?
Sorry, I just saw your comment. No it is fine to go through multiple cycles. Epoxy is the same finish you will find on refrigerators and side panels of ranges, very durable powder coat finish, but not to be exposed to UV. I did use it mainly on the inside since I wanted to use something to seal the metal and the bead area that would be durable and would not be exposed to sunlight. Hope this helps!
What psi do you set your gun and powder flow air to? I keep having trouble with my multi coat nozzle in the faraday areas
I run around 8, but can go 5 to 10 depending on what I am shooting. Are you having trouble with first coat? I don't usually use the multi coat nozzle for first coat, in farady areas I will turn the air up a touch and the voltage down. For additional coats, I can start with the voltage around 70, turning it all the way up like they recommend for the multi coat nozzle seldom works for me. I still find that shooting the first coat at a higher KV , then down a bit for each consecutive coat still works best. It is also different with different powders, and different materials. Just keep experimenting with different PSI and voltage, sometimes the PSI can be too high and blow the powder out of the tight spot. Also try spraying the powder in at an angle, like catch the farady area with the edge of your powder cloud, that seems to work well too.
What did you do to protect the silver part of the wheel. White applying the black on the back side ?
I didnt worry about it, the silver got coated with black and before the wheel went in the oven I wiped the powder off the areas staying silver
Could you have clear coated the whole wheel and the wrinkle black color for added protection?
Also a vacuum with an attachment works better than compressed air for that center hub section.
Hey Jarrod, sure but it would change the look of the wrinkle black, its pretty durable on its own. The alien silver requires a clear coat.
I agree, but I don't usually do parts that require powder removal from certain areas. The parts I usually do I can just plug or tape anywhere I don't want powder. This was actually the very last set of wheels I did, and don't see another set in the near future. I did these wheels for a friend, but got a lot of questions about powder coating, so used these to try to show the process. Thanks!
Vintage Mixers and More thanks for the replies to my questions and these came out great regardless. Great work and one of the better videos I have seen. Take care
Vintage Mixers and More the epoxy you used on the barrel, what kind and brand of powder was that. I want to use the epoxy for some structural brackets to the Mopar I'm building and if they sell epoxy powder I would rather use that for durability
so how much would it set me back to have a set of those done like that
depends what the rates are near you. Powder coating rates seem to vary wildly from shop to shop, area to area. Check with a few local powder coaters, you may find one pretty reasonable. Production shops will most likely cost a lot more.
Hey i have the same rims almost wanting something done like this. Do you other peoples wheels?
No sorry, I don't anymore, I am so busy right now with the restorations I no longer have time to do car parts, I can barely do my own lol
Do you know of anybody that does maybe like a friend of yours or somebody you can recommend
Where do you live Juan? If you look online, you should have a local powder coater in your area. I am in northern Michigan, there is one other person here that I know of, I can get you the info if you are near northern Michigan.
What kv do you shoot your powder at?
It depends on the powder, whats being shot, and how many coats. For this I started out at higher than normal, probably 80 to 90 so I could turn it down some for the other coats.
1 wheel, less than 1/4 lb per powder.
