The process of making engravings in a precise manner of various types on any kind of material that a company uses in the manufacturing of its wide variety of products is known as laser engraving. The technique has become so popular in a very short span of time that it has fast started replacing the metal tool bits which were earlier used to etch upon products.
Three workable components are there in the machine. The first component is the main laser. This is used to target or direct the beam. Second component is the controller which is basically a computer that assists in the beam movement and positioning. The third and the last component is the surface area on which the etching or engraving is actually carried out. The laser is shaped like a pencil emitting the very high intensity beam. This beam helps in engraving and etching upon the various surfaces on which it is directed. The main objective of controllers is to control the intensity of laser beam, its direction, etc so as to carry out the job in a precise way.
Usually where the engraving is supposed to be done is the point of focus of the laser. It is generally very small in size and it brings about material changes in the surface area when the intensity of thee laser increases. The material is at times burned away in case when the high amount of heat is applied. It also sometimes results in small cracks or fissures in the material. In such cases, material layers are removed and the engraving is done.
Laser engraving and etching is applied in various fields. It not only has several managerial applications but it also assists in the overall identification of the product by engraving its serial number and other details on the product. The names of the company, its logo, various signs, etc are engraved. It also engraves speed, voltage, pressure, etc and other features of the product. In the field of product tracking as well, laser engraving and etching is commonly used.
In case of manufacturing sectors, the technique helps in etching on various new metal alloys, polymers, etc. Due to so many advantages encompassed by this technique, the tool bits have been replaced by this technique. Since this is a very delicate job, great extent of precision is required which comes easily through this technique.
In the art field, laser technology is used to create personalized jewellery and also assists jewelers to engrave things like batch no, bar codes, certain specific markings, etc. This was not possible with metal tips. Since intricate patterns are needed in jewellery making, this technique is the best possible option.
