Applying the marking material. 2. Bonding the marking material to the substrate with a laser. 3. Removing the excess marking material. The first step needed to create a laser-bonded decoration or marking is to apply the marking material to the metal substrate. CerMark laser marking materials, manufactured by Ferro Corp., are formulated specifically for this process. The laser-bonding materials can be applied to the marking surface by either spraying or via a dry transfer tape. The liquid product, LMM-6000 metal-marking material, can be used on a wide range of metals. The LMM6000 is applied using conventional spray equipment such as gravity-fed HVLP guns, siphonfeed spray guns, or airbrushes. After applying a smooth, even coating of the proper film weight, the material is dried before laser marking. The product dries quickly, and drying can be accelerated by blowing air or heat across the surface. The dry transfer tape, LMM-6018 metal marking tape, is formulated for use on stainless steel. The LMM-6018 is applied just like a label or masking tape. It is supplied in rolls similar in size to a roll of masking tape. The tape is removed from the roll and then is positioned on the substrate to be marked. After applying to the metal, the tape is smoothed out to ensure good contact with the substrate and to remove any air bubbles from beneath the tape. After the marking material is applied, the next step is to bond it to the metal substrate with a laser. The marking materials can be laser bonded with CO2, YAG and fiber laser systems. The laser needed to create a laser-bonded decoration or marking may vary depending on the substrate to be marked. Some metals will require more power to mark on than others, depending on their heat conductivity and their mass. The power settings used to perform the laser bonding may be different for each application, and they are normally optimized by markwww.applianceDESIGN.com For more Information Enter 141 62 applianceDESIGN AD09074Lin.indd 1 September 2007 8/10/07 9:32:49 AM LN N E A R A C T U A T O R T E C H N O L O G Y I http://www.linak.com http://www.linak.com http://www.appliancedesign.com
