Powder coating ovens are known for reaching the curing temperature quickly, and they are easy to operate. They are designed using an innovative airflow design that is helpful in keeping the interior temperature uniform thereby saving fuel. The modern powder coating oven is designed in such a way that the user can easily reconfigure and fine tune it without spending a lot of money and time. In addition to that, this oven has durable and uniform finishes.

The size of the powder coating oven built is dependent on the needs of the user. Some of its key elements include fans, lights and heating elements all of which are recessed into its walls. In addition to that, this unit has inbuilt powder rack which fits tightly into the oven ensuring that no space is wasted. The powder coating process can be done on the rack. The rack is then rolled into your oven for curing. This is something that can add some complexity as well as the cost of the construction materials. However, you can save a lot of money by going the traditional routine.

Essential features of a powder coating oven

The following are the main features of a good powder coating oven

  • Window in door
  • Recessed lighting
  • Recessed convection ducting and fan
  • Rivet construction
  • PID controller
  • Heating elements
  • 20 and 16 gauge sheet metals

Materials used and the construction process

Every unit should have steel track and steel stud frame that is riveted together. The frame sides are skinned with sheet metal. A twenty gauge metal is used in making the different parts of the even apart from the floor which is made using a sixteen gauge sheet metal. The floor is made using a thick sheet metal to make it sturdier. Al the studs, sheet metals, and track are purchased locally from the home depots or the local metal supply companies. These materials can also be purchased online, but you can save a lot of money by shopping around.

Framing tools and materials

The frame of this oven is made using galvanized steel studs that are used in building homes. These studs can be obtained from the local Lowes and depots. A combination of steel track and steel studs can also be used.Steel tracks are easy to cut ad they can be drilled easily because they are thin (25 gauge). Rivets are used to hold the frames together. They are cheap and easy to use. Rivets can either be applied using pneumatic rivets guns or hand rivet guns. The construction process should begin with the floor frame. The floor should be measured according to the size of the oven being constructed.

All the four corners should be squared up using speed square. Once you are done with the sides of the oven floor, you should add more studs to make the structure sturdy. The same procedure is followed for the back wall and the side walls. These walls are then placed on to the floor, each at a time. They are then riveted to the floor. The oven’s ceiling is assembled in the same way as the floor. At this point, all the recessed heating elements will come into play. Individual sections should be constructed for the various heating elements using studs.

Skinning the inside

Sheet metals are used in skinning the inside once you are done with framing up the structure. The sheets of metals should be cut according to your specifications. They are helpful in holding the frames together. A thin metal sheet is preferred because it can allow faster heating of the oven.
