what type of oven is needed to cure powdercoating?

temperatures won't exceed 400 degrees, so that doesn't seem to be an issue.

what's stopping anyone from building a big electric hotbox?

 

Any type of oven would do. Even your own home oven would do lol.

Harbor freight sell a power coating oven. It a small one tho.

hrm. 18x18x18 is on the small side.

any links to a a larger for under $800

 

Any home stove/oven will do the job. Craigs list or the pennysaver for cheap ones. heck, you can probably just go pick one up from the dump for free. A lot of people just chuck the old one when they remodel.

i've got an oven the size of a smal closet, it's nice & works well. I could probably take some pix of it if your interested. (home grown unit)

inside dimensiones are like 3ft x 3ft x 8ft tall

it's fire insulated so that that it's cool to the touch on the outside while it's running, it's got a digital display for temp readout & just a small control pannel hanging off the side.

 

running can you please post pics?

 

I just use a spare home oven in my garage. But I can only do small parts

 

I bought a used home type electric oven (don't use gas) for $20. I put casters on it and a table top on it and it rolls out of the way when I am not powder coating. Craigslist often has ovens for free, as people just want the old one to go away when they replace it.

 

i use one i got off craigs list for 50.00 i do valve covers, motor cycle parts, and i can even do 15" rims. this spring ill probably make a new oven, id like to make a 3'x3'x'3 hot box just for doing wheels and smaller parts. my uncle owns a PC shop here as well, and has a huge oven big enough for tube chassis etc. i would just do big parts there

 

i was also thinking about making my own but also wanted to make it so it would hold pressure does any one have any ideas of how to seal it

 

Why do you need it to hold pressure? You don't have to bake powdercoat under pressure do you?

 

subscribed. has anyone else ever noticed that all of things that you though were unobtainable when you first started modifying cars always turn out to be much simpler than you thought?

this thread agrees with me. lol.

 

awesome. just picked out all my parts.

can you guys recommend good powder? any name brands that stand out?

i want to do my calipers first, but i dont feel like disassembling the seals and piston.

 

Eastwood or Caswell.

What kind powder gun do you have?

For good result. Prep your work.

 

going with eastwood.
don't have a gun yet. planning on the $170 package.

 

it would be nice to have an oven for powder coating and for vacuum bagging carbon fiber in one unit

is there any kind of silicone hose or something that could be used around the opening for a seal that wouldn't melt up to 500*

 

McMaster-Carr has seals like this one:


Which are available in Viton and advertised at -20 - 450 F.

Might be worth looking into.

 

yeah that could def work, thanks for the find. has anyone here made there own oven? im wandering if you can just take the element and controls from a conventional oven and make a larger box around them. and what to insulate with?

 

Tried Eastwood and Caswell and both are good, but I like Columbia best.

Yes. For insulate you can use Rigid Fiberglass insulation or Mineral Wool Insulation.

 

is that available at lowes or home depot?

 

I think so. Give them a call first. If not, you can order them online.

 

anywhere you know of online?

 

McMaster-Carr to the rescue yet again.

They have the mineral wool insulation in "semi-rigid" sheets as well as fiberglass insulation.

Once you go there, do a search for "High-Temperature Sheeting". It's on the same catalog page as the fiberglass stuff and has a max temperature of 1000 degrees F.
