Fusion has launched a new-high powered ultraviolet (UV) curing lamp system, the Light Hammer™ 6. UV curing, or drying, offers many advantages over traditional curing methods, for example increasing production speed, reducing reject rates and facilitating superior bonding, but the main advantage of UV technology is that it does not emit the toxic solvent vapours associated with alternative means of curing. Designed by Fusion's engineers, the Light Hammer 6 features several new patents and existing patented technologies, bringing all the benefits of microwave-powered UV curing to a small, but powerful, system measuring only 150mm (6 inches). The system comprises two components: the microwave-powered irradiator and the solid-state power supply. It is the power supply which gives the Light Hammer 6 its key benefit: its state-of-the-art design consists of a solid state switching engine supplying a constant DC source of power to the lamp. This achieves a higher degree of conversion than is typically achieved with AC-powered light sources and also extends the life of the magnetron and the bulb, thus reducing ownership costs. In addition, solid state electronics run cooler and more efficiently, saving money on power and reducing environmental noise. A variable power feature enables the lamp output to be matched to the machine/line speed or to the ink/coating demands and the system can repeatedly cycle from high power to very low power over just a few seconds. This fast response of the lamp to control demand means that it can now be integrated into processes without the use of the bulky, mechanical shutter, which was previously required when used in processes requiring a rapid on/off cycle.
