Where Products Are Born!
Laser engraving, which is different from laser marking, is the practice of using lasers to engrave an object. Laser marking on the other hand just discolors the surface, without cutting into the surface. The technique does not involve the use of inks, nor does it involve tool bits which contact the engraving surface and wear out. These properties distinguish laser engraving from alternative engraving or marking technologies where inks or bit heads have to be replaced regularly.
A good example of where laser engraving technology has been adopted into the industry norm is the production line. In this particular setup, the laser beam is directed towards a rotating or vibrating mirror. The mirror moves in a manner which may trace out numbers and letters onto the surface being marked. This is particularly useful for printing dates, expiry codes, and lot numbering of products traveling along a production line. Laser marking allows materials made of plastic and glass to be marked “on the move”. The location where the marking takes place is called a “marking laser station”, an entity often found in packaging and bottling plants. Older, slower technologies such ashot stamping and pad printing have largely been phased out and replaced with laser engraving.
