Universal Engraver - What is the Difference Between Laser Marking and Laser Engraving

Did you know that the word LASER is an acronym and that it stands for Light Amplification by Stimulated Emission of Radiation. The term is typically used for devices that amplify a beam of light to create a highly intense focal point. This technology is highly adopted and finds applications in innumerable range of industrial and commercial operations and usages. It is most commonly used in the manufacturing sector to mark or engrave assembly components so as to increase traceability, to ensure aesthetic sense or to indicate more information. Universal engraver reviews that while laser marking and laser engraving operate under the same basic principle and are often referred to interchangeably, there are some key differences which make them distinct from each other. While marking and engraving are similar and can be used interchangeably, laser marking is typically associated with engineered plastics and metals, and laser engraving refers to wood, plastic and acrylic.

Regulations laid by the industry and the government have made marking mandatory for product legibility and identification. In this regard, laser marking and laser engraving have gained prominence in recent years. Identification of the parts play an important role in ensuring safety and reducing margin of errors. It doesn't matter what industry you belong to, whether you work in automotive or aerospace, whether medical industry or chemical labs, it is absolutely essential that parts are identified. Universal engraver stresses that though both these terms are often used interchangeably, a business owner or a property owner must understand their uniqueness to choose the best suitable option for themselves. Their application may range from labelling parts to putting in VIN number, to putting logo or maybe just serial number - engraving or imprinting, one must know the differences!

There is no denying that the terminology is confusing but both of them are different in process, in applications and in final appearance. The decision for opting for one of these two depends on various factors, but the most primary one is the nature of the project and the material in use. The material dictates everything. For example, engraving might be the best option for some projects and marking for some. For some people, appearance is of utmost importance, engraving might feel good, but marking can look good. It is therefore important to understand the difference between them to make an informed decision. Laser engraving is more permanent in nature because the product undergoes a significant change. The process involves removal of a part of the surface. Laser engraving is most commonly used in plastic, steel, glass, wood and in some cases even leather. Under this process the laser beam burns off the surface, thereby making the imprint permanent. The advantage is that the material will never lose its mark even in harsh conditions or after rough tear and wear.

Types of Laser Engraving Methods Typically there are three kinds of laser engraving methods - laser etching, laser engraving and laser ablation. Laser etching predominantly produce shallow marks Laser engraving involves making deep marks that can withstand hard conditions, exposure and environment. Laser ablation involves removing surface coatings

Universal Engraver offers a variety of laser engraving machines that can minimise your efforts and optimise your results, for example: 15000 mw Blue CNC Laser Engraving Machine, Cylinder Column Mini Laser Engraver Engraver Machine, and 50W CO2 laser engraving and cutting machine etc. Under laser marking, the laser beam slightly alters the surface of the material without burning it. The most common form of laser marking is oxidation which involves blackening the surface of the material. Laser marking makes sense in scenarios where it is prerequisite that the material of the product remains intact.

There are many laser marking methods available. The four most commonly used are: Carbon migration: A common type of laser marking, carbon migration occurs during the heating of metal or metal alloys. The rapid heating allows for carbon molecules to migrate into the specified area. Annealing: Annealing refers to localised heating because of which the colour of the material changes. Colouring: It is the process of adding colour to an object that is being marked. Foaming: This technique is used when the desired colour is lighter than the original colour of the material.

Universal Engraver’s The Blue CNC Laser Engraving Machine, is the most ideal laser marking machine available in the market. It can easily speed up your production and increase efficiency. The machine can be used to mark on all types of materials, including stainless steel, anodised aluminium, tool steel etc. The machine offers a material engraving area of 20”x25” and is compact and efficient. The choice between laser engraving and laser marking is an entirely business option. Understanding the difference between them makes it easy to make an informed decision. Laser engraving and laser marking both play an instrumental role in part identification and part identification is crucial for it reduces error and guarantees safety. Throughout the years, universal engraver has gained expertise and expanded the capabilities of its machines and offers solutions for the diverse needs of the manufacturing industry.
