In this sort of marking process permanent marks can be made on a wide variety and range of materials using lasers as an option, laser bonding as a process was patented in the late 90's but may now that it's very finding such an extensive usage in various industries.
For example in metal products permanent marks can become in the regarding intricate logos of this company which manufactures them, various identification marks like batch number , serial number and at time even bar coding is done with no help of laser treatments.
For other involving material a the usual heat firing method was used before which used to spoil the the surface of the material outcome of the fact this was used on substances like plastic, rubber etc. which react very quickly to high temperature, but now such complex surfaces also can be marked in whatever manner the manufacturer wants as lasers do not bring about any changes constantly in their basic structure additionally the it can be accomplished in a very precise and intricate manner.
Some particular types of Lasers used in this kind of a process are:
Carbon Dioxide laser
Diode-pumped solid-state laser and others.
Not only this the laser marked materials furthermore highly durable as that can no significant change into the actual material of your handmade jewelry and also any kinds f abrasions , fissures , ability to resist chemical exposure which acids etc do not affect the actual substance.
Some particular applications among the laser marking process are:
They could be used to mark natural material like wood, rubber, hardwood etc can be engraved using very low intensity laser beams.
Markings on stone, glass and other such material where the marking in order to be done very carefully was once did be done using techniques like sandblasting, diamond tipped tool bits etc. has now been replaced using laser beams as they may be way more precise and is able to be done more ornately.
It can also used to engraving on flexographic plates and cylinder, also a wide variety of rubber plates, engraving likewise done on polymers for photographic purposes and other kind of novel metal alloys.
Thus laser marking provides for manufacturing concerns a very specific and industry benchmark way of marking out substance and also low costs too.
