Work on developing lasers began in 1960. Over the next few years more and more types of laser were developed with different laser media and wave lengths. Thanks to this diversity, lasers are used as tools in more and more sectors of industry and science.
Because of the special way in which radiation is produced, laser radiation unlike " standard " white light - has the following features:
Low divergence of beam, i.e. the light is radiated in a defined direction
Low spectral band width, i.e. the light has just one wavelength
High energy density, i.e. high output ratings can be achieved
Short light pulses can be generated
The name was selected due to the way in which the radiation is produced.
L = Light
A = Amplification
S = Stimulated
E = Emission of
R = Radiation
Benefits of laser inscription
Economic way of processing small batch sizes (as of 1 item)
Changing records possible (e.g. serial number, date, time)
No tooling times, even with different products / materials
No tool wear
Free programmability of layout, i.e. no film etc. is needed
Zero-contact inscription of the product, i.e. no mechanical damage
The inscription is extremely durable and fraud resistant
No pre-treatment needed (e.g. degreasing / cleaning) on the product
Minimum maintenance outlay
Resistant to corrosion
Extremely durable
Marking without pre-treatment
Low-cost
Precise and highly accurate resolution
Engraving in metal, wood, plastics, etc.
Marking of the hardest materials
Can be used to reach awkward "places"
Perfect for variable information, e.g. serial numbers, production date etc.
Ideal for producing tampon printing clichés
Extremely fast marking
Environmentally-friendly - no solvents because no ink is used
Marking on uneven surfaces
Marking warm surfaces
Marking dusty, oily or rusty parts
Simple and free programming of layouts
Marking and decorating glass, ceramics, metal, wood, paper etc. without process changeovers
Decorating the insides of parts, e.g. plastic caps, crown corks
360 ° inscriptions on long caps
In-line integration, easy to automate
No ink or solvent used
Well suited to all kinds of tools
Zero-contact engraving therefore no tool wear
Inscription process - beam deflection procedure
Benefit:
During the beam deflection procedure, the laser beam is deflected in an X and Y direction using two galvanometer mirrors (controlled using the PC) and focused on the component via an objective.
- Very flexible as controlled by the PC - Large inscription field - Can in principle be used for all materials
