Within the last two decades, science and technology have rapidly changed the world scenario. Now, you can talk to the person sitting at the corner of your continent, without a single interruption.
Transport, health and business is modified and now, you have to adopt them in case you want to grow your business.
In this article let us check what is laser marking technology. We will discuss various types of laser marking which are commercially adapted for increasing the marketing potential of various firms, you never know when you will need to contact a laser marking company for your international products, for further details on this topic you can check https://www.heatsign.com/.
As the name implies, laser marking technology is the imprinting of various designs and logos on various surfaces through high bema lasers.
Usually those who deal in hard materials such as thick wood, cheese blocks and steel industries use these technologies. Hardware and the packaging process of various can such as the renowned bottles require this advanced process.
Laser marking is different from laser engravings and laser etching. When we use laser marking technologies, it is predestined to change the shape of the article. First, we decide the design of computers through various graphic designing applications.
The process of disintegrating the designs on the materials and surfaces is generally termed as discoloration. In various regions, they tend to use the word designing only but if you want to know the real term then do not skip this “discoloration” term.
The difference of laser marking and laser engraving
The main difference between laser marking and laser engraving is the portion of the metal being used.
In laser marking only the surface of the material will be affected, th high bema laser will only mark the surface with certain slogans and designs, while in engraving the material is actually burnt and you can feel the curves and edges of the engraved design.
Laser marking is just like stamp, while engravings are like deep cuts and carving through laser technology.
Types of laser marking
Commercially there are four types of laser markings. In labs and for other research purposes, scientists have devised some other ways for laser marking. In this section, we will only discuss the commercially accepted and beneficial laser marking methods.
It is a sort of oxidation-reduction process; the heated laser will oxidize the surface of the metal and ultimately the color of the surface will be changed.
The change of color will decide that the oxidation process is taking place, the design will be stamped over the surface of the metal and this process will take almost two minutes depending upon the size of the designs and the metal.
This is a high-temperature melting process, the metal is first heated separately for getting the fine and sharp edges, this step is followed especially in colder countries, in warm regions, they start directly.
The high beam laser will melt the unwanted part of the metal and as a result the workers will get the desired results.
It is also a chemical process and the change of color is one of its characteristics, which will depend upon the used material.
For example, when you would stain plastic, it will ultimately get white in color and after some time the sign will be shown in black color because of burning and oxidation.
This method is specific for coated materials such as foils, anodized aluminum, and laminates. In removing we take off the upper surface of the metal.
The high energy laser beam will remove that coating without damaging the substrate, before starting the workers will have to measure the coated film for accurate removal of the films.
Have you ever seen dark signs on your leather belt and shoes, this is possible through carbonizing? Earlier people tend to use heated stamps, which you might have seen in cartoons. During carbonizing, the materials release oxygen and hydrogen or the mixture of both.
The aftereffects have got dark marks on the substrate, similarly like carbonizing another known process is foaming, which is rather like melting, during foaming the material is burnt into gases.
