The product will be used as part of the awards at a charity fund raiser organised during 2013. Wanting something different the organisers designed the medal from Aluminium and arranged for it to be gold plated. The Nd:YAG laser, at 60 watts, was used to deep engrave the image prior to plating. In order to control any surface issues, the process had the laser set in single mode and used a skimming process to remove the material in small layers. Because the plating is so thin, the amount of material removal can be small and the image will still show through. When custom production like this is required, then the cost can be competitive however, you would not want use this production method for any volume considerations.
