UV systems are used for materials that contain photoinitiators, for example in applications for curing adhesives in bonding or sealing processes or for drying materials such as inks, lacquers, paints, and clear coats. Light, especially UV light, leads to photopolymerization or radiation curing. Radiation curing is much faster than thermal treatment and allows a higher production speed while requiring less space within production machines. Panasonic offers LED spot- and line-type UV curing systems. The LED spot-type systems use one controller with up to 4 heads to project light spots with a size of up to 10mm. To accommodate the different types of photoinitiators in the material to be cured, Panasonic offers UV curing systems with different wavelengths (365nm, 385nm, and 405nm). The LED line-type UV curing system offers heads with an effective irradiation width of nearly 400mm. Depending on the work distance, the irradiation intensity can be up to 4,600mW/cm2.
