Abstract
High throughput UV curing systems for mass curing of a plurality of articles without compromising product quality. The systems comprise a plurality of UV banks, each bank comprising a plurality of fluorescent UV lamps, thereby creating a consistent blanket of UV energy. A plurality of coated articles are positioned between pairs of banks such that the UV exposure or dosage is evenly distributed for each article. The fluorescent UV lamps use proportionally lower energy per unit and generate less heat than standard UV lamps, while sufficiently curing the coating on each article. Throughput is increased compared to currently available systems because the systems are easier to maintain requiring less downtime, can cure significantly more articles per cycle, and reduce the number of rejected products.
