Ovens are the #1 source of process dirt contamination. The thermal expansion and contraction of paint overspray leads inevitably to paint particles popping off from the fixtures, carriers, & jigs. The mechanical action of the conveyors grinds these conglomerates into smaller sizes that become airborne in the turbulent zones.
The oven cannot be cycled on/off quickly, so it cannot be cleaned frequently, ensuring a buildup of potential contaminants.
OvenSaver™ products capture and isolate these particles to ensure a reduction in dirt seed defects.
