Industrial Curing Oven for Paint Finishing Uses, Features, and Controls

Industrial facilities need a finishing system that is unique to their manufacturing operations. Included among the equipment is a curing oven, the last step in the painting process. These ovens or booths raise the product’s temperature to a high degree for the coating to set. Here’s what you need to know about the uses, features, and controls are for an industrial curing oven for paint finishing.

Industrial Curing Oven Uses

Industrial curing ovens provide a clean environment for baking and curing parts after the paint application process. High temperature rated fans provide slow and consistent hot air to the cabin, while insulated wall panels ensure the heated air is contained and safe to the touch outside. Thick, insulated doors provide easy access to inside the oven and allow parts to be brought in and out quickly.

Ovens and curing booths can be designed to your specifications, including temperature, air change cycles, and more. These insulated and high-performance setups can be customized to fit your existing or new facility layout. However, it’s crucial to define line speed, product window size, hanging spacing, and product and conveyor weight before designing a curing oven.

For a complete installation package, consider pairing a sanding, priming, and painting prep area with your curing oven.

Industrial Curing Oven Features

An industrial curing oven has five main components: oven enclosure, heater unit, supply air system, recirculated air system, and exhaust air system.

  1. The oven enclosure is the environment used for curing. It includes a support structure, insulated panels, product openings, and air seals. This cabin must be designed to carry the weight and product conveying system. Accudraft uses galvanized steel on the inside and outside of the cabin to provide support and rigidity to the curing oven’s structure.
  2. The heater unit generates energy used for the curing process. To do so, a burner, supply fan, and filters are used. The heated air makeup on Accudraft’s curing oven is insulated and safe to touch on the outside of the cabin. Fresh air is drawn from filters at the air makeup unit’s base and passed through the burner cabinet, where it is heated to the desired temperature for baking and curing. The high-temperature rating of BEPL plug fans, used by Accudraft, makes them perfect for safely heating your curing oven and exhausting the hot air.
  3. The supply air system is what delivers and distributes the energy generated in the heater unit. These supply ducts should be along the oven walls and between every other conveyor. Proper placement will eliminate any cold spots and create good flow and temperature control.
  4. The recirculated air system ensures that the energy being generated is continually added to the oven. This system can be tricky, as a poor design can negatively impact the curing process.
  5. The exhaust air system maintains a safe environment and eliminates fumes from the curing process. A properly functioning system will purge the oven before every start-up and remove harmful toxins during the curing process.

Industrial Curing Oven Controls

Knowing the right temperatures and curing time will depend on the coating supplier who provides specifications. However, the controls for an industrial curing oven are quite simple. With Accudraft’s SmartPad digital control panel, all process information and settings are in one compact and easy to read unit. Fan speed, temperature control, and more can be adjusted and monitored through the SmartPad.
