One of the more novel displays at the Fakuma trade show in mid-October in Germany concerned Holo-Impact, a process for ‘exploding’ a hologram onto a mold, with energy from the blast focused as per the Munroe effect so that the hologram becomes a permanent part of the mold---and is visible on parts molded with it. The Fraunhofer Institute of Chemical Technology and five partners are working on the development. The mold running at the show—on an Arburg press—had molded 20,000+ flying discs with no sign yet of wear on the hologram. Experts at the Institute reckon the process may be of use in helping OEMs limit counterfeiting.—[email protected]
