Profile

The bake oven applies heated air to the applied coating on the substrate. Properly designed ovens will offer uniform heat (±3%) throughout the oven assuring neither burning nor under-curing the coating.

Selection of the material handling method varies directly with the production volume, part size/ shape/ weight and desired cleanliness. In general, the monorail is the most economical, flexible and reliable method of handling product.

• DOE?
• High cleaning cost?
• Crowded floor space?
• High reject rates?
• Wasted time and labor?
• Wasted energy?

If your cleaning and finishing operations are not all they might be… or if you’re just not sure… call on “Fextec” for help.

Parts finishing can be accomplished in different ways involving several technologies. The optimum design for a family of part evolves from understanding the following parameters & applying them with consistent design integrity:

• Expected results
• Quantity & configuration of parts
• Material composition of parts
• Desired material handling methods
• Understanding soils & cleanliness
• etc

• FLOOR MOUNTED
• ROOF MOUNTED
• TWO ZONE
• A - TYPE
• BATCH

This large monorail conveyor oven installation incorporates two oven: a dry-off oven which dries parts after cleaning ( 150°C for 10 minutes ) and a combination prime and finish baking oven ( 200°C for 20 minutes ). The drying oven is 44’ long; the baking oven is 38’ by 62’, incorporating multiple passes within this space. Conveyor speed is 8’ per minute.

Parts are loaded at floor level, then travel sharply upward to enter the oven. The dry-off oven operates at 150°C; prime baking is done 200°C for 15 minutes and finish baking at 200°C for 15 minutes. Conveyor speed is 4’ per minute

Note the dual controls on this two zone oven. The recirculation fans are in the top of the combustion chamber. The burners are mounted in the bottom of the chamber. When burners are mounted low, dust and dirt create a problem. Therefore, filter are required on the burner inlet

The natural tendency of heat to rise, plus the availability of unused ceiling space, makes the elevated oven effective and space-saving as well. Since the oven is elevated, no valuable floor space is used, other than for loading and unloading stations. The bottom entry and exit openings, which are self-sealing and help to control plant temperatures and conserve energy.

Truck or rack type oven offer economies in initial cost and during operation as well. Oven trucks, racks of parts or larger parts are placed in the oven through doors of convenient size and location. Time and temperature are easily controlled for any desired result in paint finishing.

Knowledgeable plant operations personnel, on seeing their new Fextec Oven assembled, often tell us that Fextec construction equals or exceeds any they have ever seen. Fextec Oven panel and general construction provide maximum strength and rigidity, minimum heat transfer or loss, plus an extremely attractive appearance.

Fextec Ovens can be installed with a variety of seals to prevent escape of heated air and fumes. The A-type oven, which must elevate, has a natural type of seal because the heated air rises into the upper, sealed portion of the oven. Exhaust type seals, in which conveyor opening are enclosed by a hood with exhaust fan, are also available.
