Jewellery Laser Hallmarking Machine

Laser marking is an etching process; therefore it does not cause any bruising or distortion of the metal. It is possible to mark both flat and curved surfaces. Laser hallmarking does not require any physical contact with the item. A very precise fiber laser-engraving machine applies it.ceramics, foil & films, leather etc.A CO2 laser is a gas laser with that A mixture of carbon dioxide, nitrogen and helium serves as an active medium. The carbon dioxide molecules are stimulated. If an infrared photo meets a carbon dioxide molecule, a new photon is created.In simplest terms, laser marking is a permanent process that uses a beam of concentrated light to create a lasting mark on a surface. Typically performed with a fiber, pulsed, continuous wave, green, or UV laser machine, laser marking encompasses a wide variety of applications.
