Principle & Characteristics

CO2 laser marking machine is carbon dioxide laser marking. The active laser medium is a gas discharge which is air cooled (Water cooled in higher power applications). The filling gas within discharge tube consists of carbon dioxide and othe auxiliaries gas. Electron impact excites vibrational of molecule and produce a beam of imfrared light with the principal wavelength bands centring on 106 micrometers.

Under the action of scanning galvanometer, F-Theta and the software, user can get the graphics, texts, numbers and symbols according to the requirements. The principal of the CO2 laser marking machine is to expose the deep material by evaporation of surface material. CO2 laser marking has no consumable cost and it can leave a permenant mark.

1. Small sixe and easy to move in co2 laser marking machine, almost all the accessories can be put in one cabinet. There are even portable CO2 laser marking machine, if the power is small(10 watt) it is easy to carry.
2. High speed high efficience, high precision, stable performance and no maintenance.
3. Easy operation. those who can operate a computer can learn it easily.
4. Wide applications, can be used on most of the materials.
5 Save cost, no need for consumables.

Function of the software
1. Can accept files with the format of BMP, JPG, DXF, PLT, AI and etc.
2. Can generate varies of serial no, MGF date, barcode and QR code automatically.
3. Support fly marking, Rotated marking, big size marking and Automatic segmentation by XY table.

Co2 laser marking machine can mark mostly on non-metal material, such as bamboo, wood, paper, ABS/PVC epoxy 2 resin, acrylic, leather, glass, ceramic, rubber and so on. It is widely used in pharmaceutical packaging, food packaging, beverage packaging, plastic, textile, leather, wood, handicrafts, electronic components, communications, watches, glasses, printing and other industries.
