Laser marking of legends and logos is waterproof, smudge-proof and durable, and can be used for very small machine-readable markings such as sequential QR codes or barcodes. Consecutive numbering can be carried out quickly, easily and cost effectively.
Using a laser to mark an enclosure provides a more resilient solution than printing because it physically changes the colour of the surface. Dark and light plastic parts turn grey at the point of marking.
Suitable materials for laser marking include ABS, ASA+PC and ASA+PC-FR, polycarbonate, polyamide (and PA GF) and aluminium. Depending on the materials involved, the following enclosure colours are good for high-contrast laser marking: off-white, pebble grey, light grey, lava and black.
OKW continues to offer photo-quality digital printing (up to 1,800 x 1,800 dpi) on surfaces with a height difference of up to 2.5 mm.
Like laser marking, the set-up costs for digital printing are much lower than those for traditional silk screen and tampo methods. This makes digital printing and laser marking suitable for lower volume production runs.
OKW’s enclosure customisation options also include CNC machining, lacquering, decor foils, special materials, EMC shielding, installation and assembly, fully bespoke enclosures, membrane keypads and touchscreens.
