Powder Coating

After my usual PC guy wanted $400 to powder coat my two aluminum chassis, I've decided I'll try it myself. I've been reading up on the PC forums and watching a few videos. Eastwood has a customer satisfaction guarantee so I've ordered their oven that my pieces will fit into and shipping was free. The chassis guys are shipping me a bunch of scraps for experimentation.

I'm pulling the trigger so to speak.

Interesting. Can you share some links to the actual oven you are looking at?

Btw, that’s stupid expensive for powder coating. The place here I think charged me $80 for several items in 2 different colors when I did my JE Labs Simple 2A3.

I don't actually use plugs for anything. A little powder in the screw holes just doesn't matter for what I'm up to.

If you have threaded holes, just chase them out when you're done. IMO the plugs are good for tight tolerance items, which our DIY creations usually are not.

It is way harder and tends to look better IMHO. The melting process brings a nice look different than paint in most cases.

I prefer it in most cases too. Downside being that not everything can be powder coated because of the heat.

I know it is too expensive but I think he didn't want the job. The other guy that was willing was very inconvenient to get to during a work week. This way, I'll be able to do other stuff if I want.

He he, I discovered that the Amazon Firestick remote has a microphone in it. I can say out loud the name of some kind of product I would never buy around that remote and ads will pop up within a few hours while I'm browsing the web. This is very powerful information, and I'll certainly be having some choice conversations with other people's Firestick remotes when I have the opportunity!

Back to advantages vs. disadvantages. If you want to use enamel paint on a metal chassis, the enamel will take a few weeks to properly harden. This is pretty painful to wait for! Powder is ready and super hard as soon as the panel cools after you pull it out of the oven.

On the other hand, there are some sprays that don't have that kind of drying time (2K 2 part paint) and you can touch them up far more easily.

Messing with my friends' alexa, etc. is a favorite past time of mine.

Curious what sort of temperature is needed for baking powder coat?

When you get the powder, usually there's a sticker on the bag with the recommended cooking time. You'll have to keep an eye on the part as it's cooking, as the powder will darken a little bit, then flow out into a liquid, then you cook as directed. The part size and the temperature of the part will make the time it takes for the powder to flow out change.

I have had one since about 2003. I still have the original eastwood hotcoat gun setup. Don't try to powder over un-prepped substrate, you'll at least need to sand everything well. I powdercoated a new hammond enclosure years ago without any prep and the powder wanted to peel off in some areas due to lack of adhesion. As was mentioned above, curing starts when the part reaches curing temp, not when the oven reaches curing temps.
