ABSTRACT:
A first bring up zone of a camel-back oven utilizes a plurality of short and/or medium wave infrared lamps to raise the component temperature up to a desired level. Once within the paint baking oven, the component enters into the bring up zone where a computer activates the requisite number of infrared lamps at the proper intensity to achieve the desired component temperature. While the infrared lamps are activated, inlet air is directed over the lamps to prevent them from overheating. The invention allows for smoother car finishes by preventing bubbling and pops and raises the component temperature more quickly than conventional dark radiation panels.
