Taikisha - Industrial Paint Cure Oven

There are several different varieties of industrial paint oven:

1. E-coat Oven: The first oven in a paint shop is the E-Coat Oven. Also known as the ED, PTED, or ELPO oven. After the Electro-coat is applied by submerging the parts in the E-coat tank, the parts are rinsed and sent through the E-coat bake oven to dry and cure. The E-coat oven is the hottest oven in the paint shop at temperatures of ~350°F. The Electrocoat paint is held at temperature for 20 minutes where it cross-links and hardens. E-Coat is a water-based paint, so there`s very low amounts of VOC in the E-coat oven, but it does tend to create smoke at high temperatures when the E-Coat drips off onto the hot oven surface. Oven air turnover and exhaust is required to keep temps up and smoke down. An air pollution abatement system like a Regenerative Thermal Oxidizer (RTO) may be needed to control the amount of smoke.
2. Sealer Oven: The second type of oven is the Sealer Oven which is the only paint oven that does not cure a paint coating layer. Instead, the sealer oven is used to dry and cure the polymer-based sealer applied to the seams of the vehicle to make it water-tight.
3. Primer Oven: The primer oven is used to cure the primer layer of paint, which coating be liquid sprayed or powder coat primer. The primer oven is optional and is not used in a 3-wet paint process where the primer, basecoat, and clearcoat layers are applied after sealer oven and then cured together.
4. Drying Oven: The dry-off oven is optional often not used. It is only used when the primer coat is wet sanded, rinsed, and dried before applying the base and clear topcoats.
5. Heated Flash Off (HFO): Heated Flash-off tunnels or HFOs are essentially small ovens that only heat up to 160-180°F to dehydrate the outer layer of waterborne paint layer before applying the next liquid spray layer. The HFO is not needed for a solvent-borne paint, instead an ambient temperature flash off tunnel may be used. Two HFOs are used in a 3-wet paint booth process, between prime and base coat booths, and between base and clear coat spray booths.
6. Top Coat Oven: The final and most important oven, it finishes the final paint cure, determining the finish quality that all customers will see. If there`s no primer oven, as in a 3-wet process, then the Top Coat oven is responsible for fully drying and curing all three layers of primer, base coat, and clear coat. The topcoat oven is almost always an indirect-fired oven with heat exchanger to preserve the color integrity of the base coat and color coat layers.
