Electronic enclosures manufacturer OKW has added new laser marking technology to its wide range of customization services.
Laser marking of legends and logos is waterproof, smudge-proof and durable. It is ideal for 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 color 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 aluminum. Depending on the materials involved, the following enclosure colors are good for high-contrast laser marking: off-white, pebble gray, light gray, 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 0.098”. Like laser marking, the set-up costs for digital printing are much lower than those for traditional silkscreen and tampo methods. This makes digital printing and laser marking ideal for lower volume production runs.
OKW’s enclosure customization options also include CNC machining, lacquering, decor foils, special materials, RFI/EMI shielding, installation and assembly, fully bespoke enclosures, membrane keypads, and touchscreens.
