As a leading international company we offer UV systems that are based on environmentally friendly technology to cure UV inks, varnishes, silicones and adhesives. Warm air infrared systems complete our product range.

The UV curing process uses UV energy and light from the visible light spectrum in wavelengths from 200 to 480 nm. UV energy “cures” inks and varnishes in a fraction of a second. A UV system consists essentially of the following components: UV lamps, reflectors, lamp housings, a cooling system and an electronic operating and control system. A range of additional options can then be added as required.

IST METZ offers either stationary or mobile UV measurement units. Stationary units are integrated into the UV system and the production process is therefore in a closed-cycle and consequently runs under constant conditions. Mobile measurement units are available as inspection units and units for measuring specific UV radiation intensity

There are two measuring devices available. The UMS-2 which is composed of a display and of a sensor head which is available in two versions. The UMF sensor head is universally adaptable, whereas the UMI sensor head requires a preparation of the unit.

Where there is a conveyor, the UMD-2 dosimeter can be used. It is equipped with a measuring probe situated on the back side of the device.

The geometry of the reflectors is optimised using state-of-the-art ray tracing software. UV lamps and reflectors are read into the program as 3D models. The static receiver levels of the radiation are representative surfaces for UV drying and are displayed at various distances. The definitive factor is the lamp axis and the typical distances from the substrate or coating material. As the reflector geometry changes, so does the ray tracing. The ray tracing of the UV system is subject to different requirements depending on the application. During work with particularly temperature-sensitive substrates, parabolic reflectors that produce a beavertail ray are employed. In other cases, elliptical reflectors are advantageous, because they concentrate the ray. The radiated power per surface is measured and displayed as watts per square millimetre in a 3D graph. Ray tracing is used to calculate and optimise the UV efficiency of the unit, the homogeneity of the radiation and the distance characteristics.
