+ | The work involved in powder coating is about 90% Prep. ((mct496 of the XLFORUM http://xlforum.net/forums/showthread.php?t=1617845&page=2)) \\ | ||
+ | It's good to bake parts before powder coating at a higher temp than you would powder coat at to bake the impurities out of it. \\ | ||
+ | Also you can flash heat the parts with a propane torch to clear any moisture that may have been attracted to the cleaned part. ((simeli of the XLFORUM http://xlforum.net/forums/showthread.php?t=1617845&page=2)) \\ | ||
+ | And preheat any tight areas and drop the powder on the gun as you coat to make sure that it gets coverage there as well. \\ | ||

+ | The heat is supplied from the bottom and one side causing a natural air rotation inside the box. \\ | ||
+ | In testing, ther was around 10 degree difference in the temp of the rails (rack supports). \\ | ||
+ | (which is actually less than the temp rise and fall between heating cycles) \\ | ||
+ | |||
+ | The only "glue" that is used is 3M "77". \\ | ||
+ | (on the outside of the inner box (steel) and the inside of the outer box (plywood) which is cover with aluminum foil) \\ | ||
+ | The gasket is attached using RTV red and was cooked out during testing. \\ | ||
+ | The cement board is attached by pop rivets and bolts. It was also cooked out during testing. \\ | ||
+ | The oven is also used to gas out the parts during the cleaning process, so everything is gassed out before any coating is done. \\ | ||
+ | Flash heating with propane gets the metal hot enough so that any moisture is evaporated. \\ | ||
+ | Also any lint or dust that may be present is burned off. \\ | ||
+ | Powder is applied quickly after flashing or in the case of larger pieces flashing continues ahead of the powder. \\ | ||
+ | |||
+ | In use is a regular household style oven controller. \\ | ||
+ | But there are four of the internal oven thermometers that will be mounted inside. \\ | ||
+ | Plus an external probe thermometer that goes through the door (noticed in the pictures below). \\ | ||
+ | It should be about 30-35 minutes of actual time to watch the work and manually control. | ||
