Batch Cure Ovens for Georgia Coating Shops
A batch cure oven is the workhorse of shops that load parts on carts or racks rather than a conveyor. Parts roll in, the doors close, the oven brings them to temperature, holds and releases. Simple in concept, but performance depends on burner sizing, recirculating airflow, exhaust, door seals and how the oven sits in the building. Double D Mechanical installs, relocates and connects batch cure ovens for Georgia coaters and manufacturers.
Discuss your installationCuring Heavy Electrical Steel
Heavy steel parts absorb a lot of heat before the coating itself reaches cure temperature. Transformer-related components, the kind of work behind the Virginia Transformer plant in Rincon, are a good example. An oven curing thick parts needs enough burner capacity to recover quickly after the doors open and enough airflow to heat parts evenly from all sides. Undersized ovens lead to long cycles and under-cured edges.
Gas, Exhaust and Electrical Connections
Every oven install covers the same core connections.
- Gas piping and regulator sized for burner input, with shutoffs and test points
- Exhaust stack through roof or wall to remove solvents and combustion products
- Electrical feeds to burner, recirculation fan, exhaust fan and controls
- Safety interlocks and purge sequence verified at startup
- Temperature controls and recorder or data output if required
Short Transfer From Spray to Bake
Placing the oven close to the powder or paint booth shortens the trip for coated parts and reduces the chance of damage. But oven heat and booth airflow need separation so warm air does not drift into the booth or booth drafts do not pull heat from the oven doors. In smaller Atlanta-area shops, we often work out a layout where the booth and oven face each other across a short transfer aisle.
Moving or Expanding an Oven
Ovens are built from insulated panels and can be disassembled, moved and reassembled. Some designs can also be extended with additional panel sections to make room for larger parts. Either way, the burner, fans and controls need to be checked against the new size.
Planning a booth or oven project in Georgia
Crews mobilize from Houston; Georgia is roughly 700 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Georgia is concentrated around Atlanta, Savannah, Augusta, and Columbus. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive assembly and EV, aerospace, transportation equipment, and heavy machinery.
Hot, humid summers and mild winters put the emphasis on make-up air cooling or tempering, filter change schedules and keeping intake away from loading doors.
Frequently asked questions
How large should our cure oven be?
Large enough for the biggest cart load with clearance for airflow around parts. Burner capacity must match the oven volume and the heaviest load you plan to cure.
Can a cure oven be used for both powder and liquid coatings?
Many ovens handle both, but solvent-bearing coatings need exhaust sized to remove solvent vapors safely.
Why are some parts under-cured?
Uneven airflow, overloaded carts, burner capacity too low for heavy parts or a thermostat not reading part temperature accurately.
Can an oven be extended?
Panel-built ovens often can be extended. Burner and fan capacity must be rechecked for the larger volume.
Do ovens need make-up air?
Oven exhaust removes air from the building, and burners need combustion air. The building should have enough make-up air to replace it.
