The ultraviolet-based hardening of lacquer coatings has a number of advantages from the application of solvent-free systems, to the limited use of energy and materials due to reduced coating thicknesses, to the re-usability of the overspray substance. However, the use of the UV hardening technology for three-dimensional component parts involves some technical hurdles. IST METZ GmbH of Nürtingen, Germany has produced, on the basis of computer-simulated calculations, a UV coating apparatus with a flexibly-fitted reflector which has the capacity to inert the radiation area.
Thanks to the development of modern lacquer-coating systems, a coating layer can be hardened with UV radiation in just a few seconds. To properly harden the coatings of 3-D component parts, however, it was previously necessary to work with a number of UV lamps in order to irradiate all areas of the parts evenly.
With the new UV system MBS®-3D from IST METZ, however, three-dimensional objects can now be irradiated evenly and cost-efficiently with just ONE UV lamp. The use of solvent-free lacquer coatings from the LANKWITZER LACKFABRIK GmbH, developed specifically for this process, results in component parts of the highest quality.
The adjustment of the MBS®-3D can be readily computer-simulated, so that a quick adaptation to new component part forms is enabled. This results in further advantages to the user, such as significant reduction in costs associated with UV-apparatus investment, electricity, and replacement parts. Reductions in energy use of 50 %, and an 80 % reduction in the use of photoinitiators, can be realistically expected from the new system in comparison to the
traditional processing of solvent-free lacquers.
