Laser Etching

Example of Product: Laser Etching

  • Back-lit symbol indicators are made from transparent plastic and completely coated with an opaque varnish. Then this coating is partly removed by the laser - thus creating the desired symbol. When the finished symbol indicator is back-lit, light can only come through the laser-etched area.

     

  • Keys and symbol indicators with markings on the top surface, such as PC keyboards or device keypads, are moulded from pigmented plastic that changes its colour during laser processing.
