washers, dry-off ovens, incinerators, pretreatment, electro-coating, spray booths, flow coaters, dip tank, curing oven, conveyors, waste treatment & air make-up. A complete paint finishing system consists of integrally designed combination of equipment or single machine that conveys parts through the cleaning, pretreatment, paint application & baking steps to deliver a finished part
Cleaning the substrate is the single most important step in ensuring a successful painting operation. The mechanical quality of the pretreatment equipment and the chemical quality of the pretreatment solutions are equally important and must work hand-in-hand.
Adding a phosphate coating to the pretreatment process enhances the coating characteristics.
The dry-off oven applies heated air to substrate to eliminate moisture. Proper part design facilitates draining and consequently minimizes dry-off times.
Major types of paint system fall into this category
Defining your criteria relative to operational characteristics, coating properties, initial capital expenditure & operational cost will determine the paint system. We have included the powder system & the wet paint system.
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.
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:
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.
An exclusive Fextec development, induces an air movement which helps to obtain remarkably even temperatures. The air movement is induced by Fextec high velocity nozzles. The nozzles also prevent direct impingement of heated air on the work surface, a notable cause of “skin-drying” and resultant bubbles and blemishes.
In selecting burners for an oven, Fextec engineers concentrate on the total needs of the job at hand, then allow for a reserve capacity which will handle higher work loads with out expensive alterations. This provides the greatest overall economy and equipment flexibility because the burners are efficient throughout their operating ranges.
Fextec Oven are usually designed with the combustion chamber as an integral part of the unit, streamlining the appearance and eliminating the need for exterior dust work. This compact arrangement also reduces power requirements connected with excessive dust-work, saving floor space as well.
When desired, intake air filter will be provided, minimizing intake of dust which can cause finish flaws. The filters are arranged for quick and easy changing without use of tools. The disposable filters used are frameless, eliminating the usual cardboard frame as possible fire hazard.
Our oven are constructed of pre-fabricated panel for easy erection. All parts, panels, structural, duct work, wiring & piping are keyed to assembly drawings & manufactured to fit easily, quickly & precisely in the field. He purchaser can, in many cases, erect the oven with his plant personnel under our supervision, for significant saving. For more complex ovens, we provides complete service.
In a direct fuel-fired system, the products of combustion are allowed to come into contact with the work; the combustion equipment can be located inside or outside of the oven. While gas is generally used with a direct fuel-fire system, modern improved handling & firing equipment, has increased fuel oil use in this area.
An indirect-fired system does not allow products to come into contact wit the work. Electric and steam heating are common choices, or fuel-fired equipment may be used in conjunction with a heat exchanger to separate the products of combustion from the oven atmosphere.
The brief outline below describes the most popular fuels being used today. You may want to investigate the possibility of using one as an alternative to back up your present system, or in combination as a supplement.
(natural and manufactured) Generally considered and a clean, convenient and easy to use fuel. Work loads are commonly heated with gas by the direct-fired method, with no adverse effect from the products of combustion. However, as the availability and overall cost has changed, it may be to your advantage to check the alternative fuel in your area.
Always an attractive choice for industrial users. It has enjoyed a rise in popularity due to recent improvements in burner and fuel handling equipment technology. Many of the problems that once plagued the use of oil with direct-fired oven equipment have been eliminated, and indirect-fired systems are easily designed and installed when needed. A safe and convenient storage space is required.
