SolidWorks Rendering of the Powder Coating Oven Electronics Box
Earlier this year I started buying parts to make a Powder Coating Oven.
Controls inside the finished PCO Control Box prior to wiring
I will try to post images later to help others make their own PCO controller …

The goal is to have a Portable Powder Coating Oven (PCO) with removable panels that can be configured into different shapes to allow for powder coating rectangular boxy shaped items as-well-as long thin items by heating the same volume of air with 2 heating elements. ( Total of 5170 watts )
Powder Coating Oven on Wheels allowing to to be moved anywhere in shop
Also a portable (Plug-in) PID Controller for the Powder Coating Oven … with the bonus that the PID Controller can also be used with my Beer Home Brewing Equipment and a future outdoor Meat Smoking Hut 🙂

For this Project my plan was to first draw in all the purchased parts and then start designing the rest of the items using SolidWorks CAD Software.

Powder Coating Oven Parts drawn into SolidWorks
Attempted to order as many parts as possible off of AMAZON.com
Dayton 1TDV2 High Temperature Blower, 115 Volt, 129 CFM
As they arrived, I weighed the parts and drew them into SolidWorks …
Measuring a part’s weight with a digital scale
SolidWorks allows me to make the CAD part’s weight, and center of gravity, the same as the real-world part, so completed Assemblies are the correct weight.
The weight of the actual real-world part matches the SolidWorks CAD part
SolidWorks also allows users to make Photo-Realistic renderings of the parts for presenting a visual of how real-life item will appear when finished.
SolidWorks Renderings of Parts for the Powder Coating Oven
I decided to 3D-Print many of the parts for the Oven’s Control Box …
3D-Printed Side Air Hole Vent Covers for Electronics Box
First designed the Powder Coating Oven’s Electronics box with SolidWorks …

SolidWorks CAD Rendering showing the side Vent Covers
One of the benefits of using a 3D-Printer is designing any shape needed without worry of ‘draft angles’ which are required to make plastic injection parts.
For example, I wanted to be able to switch out different size/models of square shaped PID Controllers & Digital Timers.
Rounds Cutouts in Sheet Metal to Mount Square Controls
So I designed and 3D-Printed a mounting setup which allows ‘square’ controls to go in a ’round’ hole easily drilled with a 2.5″ hole saw using a drill press.
Mounts to put a Square PID Control into a Round Hole
You can download the .STL files for 3D-Printing the Square Mounts for Round Holes drilled with a Hand Drill and Hole-Saw
I put the .STL files for 3D-Printing these PID Mounts on GrabCAD
Also designed and drew up some Cord Stop Clamps ( .STL Files )
3DP Cord Stop Clamps to Keep Cords from Pulling Out of the Control Box
I like to show lots to dimensions in my drawings to prevent mistakes 🙂

Tested the 3D-Printed parts, and the purchased parts, within the sheet metal cutouts prior to welding & painting the Electronics Box.

The electrical Terminal blocks I bought didn’t work, so I designed some …
Uploaded the 3Dp .STL files to GrabCAD ~ Link: 3Dp Terminal Blocks
SolidWorks Transparent View of the Electrical Connection Terminal Block
Didn’t have 1/8″ thick Copper so found some Aluminum angle in scrap bin …
Drill and Tap Size Dimensions for creating the Terminal metal bar
Drilled and Tapped the Aluminum and then cut it to the correct size …
Tapping Threads in the No.6-32 and No.10-24 Connection Holes
3D-Printed one for White wires, and another for Black wires, and the ABS 3D-Printing material acts as an insulator for the 120V electrical connections.
Aluminum or Copper Flatbar sections press into a slot in the ABS Terminal Block
The Cover keeps the screws from falling out even if they become loose …
Different Size Wire Terminal Ring Connections can be used on Terminal Bar
I will probably switch out the Aluminum with Copper flatbar when I get some.
3D-Printed ABS material Cover protects the metal area of the connections
A specific feature I wanted for this (PCO) Powder Coating Oven was the ablity to know the cost of the electricity used while Powder Coating parts.
bayite Amp Volt Watt Multi-Meter purchased from AMAZON.com
The multi-meter comes with a ring which needs to go around the L2 electrical wire to know the Amps being used, so I designed and 3D-Printed a stand.
3D-Printed Amp Meter Ring Stand fits inside Electronics Box
Below is a SolidWorks rendering showing the wiring and Amp Ring Stand.

The finished 3D-Printed Amp Meter Ring Stand Mount for Powder Coating Oven
Tested each of the parts prior to mounting the in the electronics box ~ In the photo below I have the baylite meter setup to test 120v amperage; however, the meter is wired to 240V power in the Powder Coating Oven control box.
Testing the kWh Amp Meter unit prior to installing the the Electronics Box
In future posts, after fully testing out the Powder Coating Oven, I will show the wiring in SolidWorks, which is easier to view than the real-life wiring because I will be able to hide, or make transparent, other items in the box to show specific wires going to specific items.
SolidWorks Transparent View of Powder Coating Oven Control’s Wiring
I have already uploaded many of the CAD parts to GrabCAD.com …
SolidWorks Rendering of Switches used in the Powder Coating Oven designs
Tried to keep most of the items as Single part files; yet, still allow the parts to be adjustable, such as allowing switches to be viewed as ON or OFF.
The SolidWorks CAD switch can be set to show it as ON or OFF
Made the gap adjustable so the switch fits on other material thicknesses …
Gap of the Switch can be changes to match the thickness of metal
The LED Readout numbers can also be set for Tutorials & User Manuals …
The AUBER PID Controller keeps the the Oven’s temperature consistent
I try to use metal from my scrap metal bin to make equipment for my shop and sometimes the metal is heavier than I would normally use.
For example, the sheet metal for this PCO (Powder Coating Oven) Control box is 0.135″ thick and I would probably normally use 0.075″ thick sheet metal.
Welding the Powder Coating Oven Control Box Sides Together
After drilling & cutting all the holes, I welded the Control box sides together …
The finished sheet metal PCO (Powder Coating Oven) Control Box
Since this unit is for my shop I painted the PCO Control box Flat Black …
The PCO Control Box with Bolt-On Top & Back Plates
The Top & Back plates bolt-on to make the inner Controls easier to wire …
Painted the Powder Coating Oven (PCO) Control Box Flat Black
After the paint cured I started adding the controls & switches …
Installed the the Front LED Lights, Switches, Timer, and PID Controller
Noticed I was one ON/OFF switch short … They came in a Pack of 5 … *sigh*
Back on AMAZON to order more … For some reason I thought there was 6 🤔
All the Powder Coating Oven electronic parts fit in the box as designed
After tests realized I didn’t need the Air Cooling fan but added one anyway.
Next Step is to add the 240V Outlets to each side of the PCO Control Box
Everything on the PCO is powered from outlets & extension cords, because this is a portable Powder Coating Unit that can be taken to different locations.
This Electronics box can also control a Meat Smoker & a Home Brewing system.
( I wanted a multi-use Control Box for future projects ~ Whoo Hoo!! ) 😜

The Amber Light on the front lets users know 240V power is plugged into the Control box … When dealing with 240 Volts – Safety, Safety, Safety!! ⚡
In addition, the Amber LEDs on each side of the control box light-up when the Contactor Switch is providing 240V power to the 240V side outlets that are connected to the Powder Coating Oven’s Heating Elements.

That’s All for Now 😜
Emergency Stop added to the front of the PCO Control Box
I found the eStop button and added it to the PCO Control Box design …

Made a temporary stand/mount for the PCO Electronics Control Box …
I think PCO Stand/Mount sort of looks like a Robotic Kangaroo Rat
Already has the nickname of ‘Roo-Rat’ 😜

I uploaded my SolidWorks ‘Working CAD Files’ to GrabCAD for anyone that would like to see how I tested the wiring.
The wiring in the model is not complete, but it will show how I wired the Auber PID Temperature Control, as-well-as the Inkbird Timer Control and the Digital Amp/Volt Meter.
