What temps should I be shooting for in a powder coat oven??. For aluminum parts or steel parts??. I am looking at this one:
5zvrn-3641198538@sale.craigslist.org
Sure seems like 700 is all full hot!!.:eek:
The seller emailed me back telling me the oven ranges temps from 250 to 700.I'm still waiting to hear back from him about the internal dimensions.
The question mainly lays in aluminum rims.I certainly want the best in longevity and finish,but I do think about distortion baking the parts too hot.
Yes I do know most buy a used home oven,I was thinking and not really knowing,that different powder coating requires different temps.Also thicker steel parts might require hotter temps to cure like a-frames.
Well Aluminum starts to melt around 1200 F and steel is a bit more so you won't hurt anything at 700F ...Unless you don't use gloves
Have you looked at any of the powder manufacturers? What temps do they recommend? I'm sure they're not all the same.
Most all powdercoating temps need to be around 360-365 degF and that's for all metals . For beginners you want to have a good digital heat gun so you can see how hot those temps are when you pull the piece from the oven. As you know all ovens are not the same and they can vary heat.
You also want to pre-heat the parts, about 15-20 minutes, so they can allow for out gassing, especially aluminum parts. You heat the part to temp and then apply powder. The powder will start to melt and then you put it back in the oven for another 15-20 minutes.
If you do not out gas the parts, what happens is you apply the powder and little bubbles will pop on the newly applied powder.
Plus home ovens suck at temperature control.....terrible hot spots vs. cold. Ovens with circulation are better.
Thanks for the advise guys.
The seller got back to me:
Gary,
Internal dimensions measure 14"x14"x14".
The manufacturer is Blue M Electric Company.
Seems small.Anyone ever heard of that manufacture??.
Well I kind of answered my own question by looking on Ebay:

This one I think is one I should pass on.Aside from my own use,I was considering taking in side work the size of wheels on down.What you guys think of that??.
I think you'd have to buy all the equipment required and PRACTICE, PRACTICE, PRACTICE on your own pieces to learn how to do it before you even think about doing work for others!!!!!!Quote:
