Super wider UV curing lamp means lamp provides curing width over 1700mm.
For graphics printing and coating business, more and more clients are looking for a more efficient printing process to reduce production cost. Therefore, our clients also need wider web printing or coating machine equipped with Super wider UV curing lamps. But super wider UV lamp is not only just wider. Compared with a standard width UV lamp, super wider lamp need to consider more than the width.
DPL Super wide Cold UV curing lamp at 2000mm with specially coated reflector and our pattern design on lamp construction. For example, from the top to two side frame of lamphouse, there is UV radiation refect coating. When UV lamp is on, these coating layers will reflect light to the bottom quartz window. Quartz window has very high UV transmission, means more than 95% UV light will pass throw. In order to reduce the production cost, there are many manufacturers use a cheap reflector or even don’t use specially coated UV reflector. But as you know, more than 60% light energy of UV lamp is IR. The problem of IR is to dry the solvent or water-based content inside of UV Ink or lacquer. The Result is the outside of ink is dry, but inside ink cannot be dried. Because the dried top side is too hard to go throw.
Inside of lamphouse, DPL high-efficiency chilling channel can cool down lamphouse frame by automatic controlled chilling water. The chilling control sensor can automatically increase or decrease water flow.
DPL Super wider curing Lamps are designed for super-wide printing and coating machine. Lamp carries on DPL’s focus on cold-curing temperature and uniformity, which is suitable for super-wide touch screen or printed electrics process.
