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...
The process of laser engraving or marking is one of the most preferred ways of inscribing on metal surfaces, where in a focussed beam of laser light is used to carry out the process. While this process can be implemented on various materials surfaces, there are certain materials that may not be so suitable as well. Material surfaces that are fragile and sensitive to lasers cannot be subjected to lasers. However material surfaces that are durable and tolerant to lasers can be successfully used to carry out the task of laser engraver and marking. Naming a few material surfaces that are commonly used, Aluminium both anodized and non-anodized, Stainless Steel are the ones that are extensively preferred, but all the same magnesium and lead also can be categorised as the metal surfaces that are suitable for the job. A deeper review reveals why these metal surfaces are considered as ideal surfaces for laser engraving and marking. Aluminium is such a metal that is very wid...
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...
