Marking :

Marking is the most current laser application. Needs are huge, notably for products tracability. Laser makes a permanent marking in the material thickness, without ink, that can be invisible to the naked eye...

 

The focused laser beam modifies the material surface so as to let appear visible contrasts, colored or not. According to the laser power, it is be possible to mark in depth the material with a small heat impact and at high speed.

 

Advantages of this technique :

• Possibility to mark a wide range of materials with a large flexibility
• Marking a series numer, barcodes, logos
• No special requirement for the surface quality of the material to be marked
• Easy in depth marking
• Direct treatment of the finished part
• Speed : up to 5 m/sec

Micro machining:

Laser is the only technique that can be used for the manufacturing of parts of small dimensions. Micro machining concerns all industrial sectors, like micro mechanics, micro electronics or medical. It works with classical applications like cutting, drilling, engraving, marking. Drilling of holes, of calibrated grooves for microfluidic, cutting of masks of dimensions less than one millimeter for scientific instrumentation or microscopic engraving.

 

Advantage of this technique :

The precision of the process and a very precise control of the laser energy give this application the qualities required for microscopic processes. Precision cutting of films of thickness less than one micron, intra material marking for tracability requirements and safety marking take advantage of this technique.

Cutting:

Laser cutting stands out as the reference among other technologies of sheet metal cutting. Characteristics and powers of laser sources have considerably improved and offer a wide range of applications and possibilities.

 

Laser cutting can be made with a CO2 or a Nd-YAG laser. Cutting with a continuous Nd-YAG laser give performances and results comparable to the CO2 laser for metallic materials up to 3 or 4 mm thickness. 

 

Advantage of this technique :

• Cutting of a wide range of materials : wood, plastics, paper, steel, aluminium
• High speed - flexible process - precision + or - 0.2 mm
• Possible transport with fiber optic - precision + or - 0.02 mm for pulsed lasers
• Perfect control of the deposited energy
