Marking :

Laser marking is one of the most popular laser applications, growing with the increased needs for traceability, and the branding of material parts. Its main advantages reside in an inkless permanent marking in the material than can be made invisible to the eye.

 

The focused beam will modify the material surface, inducing a visible contrast between coating and marking, including a reproducible coloring.  It is possible to realize a very localized and deep marking with a high process speed, limiting the heat damages around the marking. 

 

Advantages of this technique :

• Possibility to mark a wide range of materials with a large flexibility
• Marking a series numbers, 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 technology is one of the most used techniques for the manufacturing of submicronic and submillimetric parts. Micro machining is used in most industries needing precise and cheap machining. Industries using laser range from microelectronics to biomedical, and the field of applications being in a growing trend, one can say that laser is now a widespread technique in most fields. Applications replacing classical processes such as cutting, drilling, engraving, marking are becoming more an more popular. Precision of laser machining allows new possibilities in instrumentation, microfluidic, microelectronics and such.

 

Advantage of this technique :

High precision with low damages around the operation zone allows microscopic precision. Precision cutting of films of thickness less than one micron, intra material marking for traceability requirements and safety marking take advantage of this technique.

Cutting:

Laser cutting is nowadays considered a reference in the sheet metal cutting field. With laser technologies improving, becoming cheaper and more and more reliable, a wide range of applications and possibilities have been made possible.

 

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
