Laser etching, marking, and engraving are the most versatile modern inventions that are used in almost every industrial sector. While the difference between the laser engraving and laser marking and laser etching is quite evident, the terms laser marking and engraving are confused at times. Laser marking, is a method that leaves markings on a surface material of an object, including colour change, owing to chemical alteration. Laser engraving is the method that is carried out by inscribing on an object surface. Laser engraving does not involve any inks or dyes, so it gains an advantage over the laser marking, wherein the replacement of tool bits like the ink heads need not be done. Laser marking has its own pros like the preservation of surface without any impact on it, since it uses colours and dyes to mark on the material surface thorough the laser techniques. Laser-sensitive polymers, metal alloys play an important role in this method. The method in general is a...
Laser marking technology is applied across a wide range of industries in order to exercise the aspect of identification in case of patented spare parts and other products. Ranging from very simple automotive engine number marking to the most sophisticated aerospace industry, laser beam technology has been considered as one of the vital and guaranteed techniques by all standards. However laser marking and engraving resolution is certainly not a single or free sized solution that can fit into all the requirements. Choosing a laser technology for your specific application is also quite tricky issue and has to be analysed along with certain key factors that govern the process in choosing the best knowhow in order to get the desired results. While discussing about laser based applications and the scope of this invention, it is quite interesting and amazing. Most of us have a feeling that laser marking machines , engraver and etching are one and the same because they hav...
Laser marking and laser engraving are two exceptionally advanced, but yet based on a simple scientific principle technological inventions. These methods are used in a variety of industries like the automotive industry, electronic parts manufacturing, medical & scientific parts manufacturers and so on. In the recent aerospace research sector laser marking has been the most preferred method to make markings on vital and critical components of the equipment and space vehicles as well. While discussing about laser marking machine , the most common methods of execution are annealing, carbon migration, engraving, etching and coloration. In order to understand how this technology works on different material surfaces, it is very much necessary to know the principle on which it is based. To put it in a very simple sense, it works by focusing a beam of light amplified by the stimulation and emission of radiation, which is focused and fixed towards a particular area on the...
