How to Build and Design a Powder Spray Furnace

An oven or infrared heating is necessary to cure the powder over some materials for the powder coating process. In coating large parts, you can either purchase a fairly expensive powder coating oven or make your own oven. If you want to build and design your own powder coating oven, then here are the steps that you have to follow for a successful powder coating oven project.To start with the framing, you must assemble the floor square section first. You must overlap the studs so that they can sit inside of each other on the corners.

Keep them in place with a locking c-clamp and place a rivet on each corner. Add more rivets on each corner until all four sides are secured. Repeat this process on your walls and ceiling. Just make sure that you rivet the walls on top of the floor and the side walls to the floor and the back wall. Once you have done with the framing, you must begin skinning it with sheet metal. You must obtain long straights cuts of galvanised steel sheet metal so that you can keep your oven free from rust.

The recommended thickness of the sheet metal ranges between 16-gauge to 26-gauge. For this project, you can place a 16-gauge sheet metal as the first layer on the inside of the floor and rivet into place. Then, add some stud supports on the bottom. As soon as you have skinned the entire oven interior, you can now work with your heating elements by cutting four cut-outs using a pneumatic cut-off tool. Your cuts must be a straight-edge and a square.You can now install a convection fan on the top of the oven for it to circulate the air from the top of the oven down to the bottom.

This fan Flocking Machine helps equalise temperatures throughout the oven. The ductwork inside the wall, on the other hand, brings air from the top to the bottom. It is wrapped around from the sidewall to the top of the oven to the fan. And for you to prevent the forced air from leaking into the oven frame, you must use a high-quality sealant for your ductwork. When constructed correctly, your convection system can pull up the air through the top of the oven. This air is then ducted back down the sidewall and into the bottom of the oven. This system can prevent temperature fluctuations while the oven performs powder coating.
