Prima Power Laserdyne (Champlin, MN, US) has introduced LASERDYNE 795 and 430 BeamDirector, laser-based surface texturing systems that can add texture to metallic molds and tools. LASERDYNE produces blind, or partial depth, holes and indentations from a few micrometers to a few tenths of millimeter in depth. This process is currently used to form precise and detailed textures on the surface of metals. LASERDYNE laser texturing is said to be particularly well suited to 3-D surfaces and features easy-to-program systems, including macro programming blocks that create complex rows of features on cylindrical and flat surfaces, respectively. LASERDYNE and can be applied to virtually all metals and alloys, including mold steel, stainless steel, and titanium, as well as a number of plastics that absorb the laser beam. The company notes that compared to chemical processes, laser texturing does not involve the toxic or corrosive chemicals used in chemical etching, and it does not require tooling (artwork) to define the pattern because the texture detail is created by the laser beam.
