Laser Marking

Achieve permanent, high-precision marking for product identification, traceability, serialization, and branding across diverse industrial applications.

Laser marking is an ink free, contact less, , permanent marking solution that is carried on directly on the part to be marked. It fulfils all regulations and uses a fine spot laser beam that focuses on the surface of the product. The laser beam slightly alters the surface without burning it,typically inducing a color change within the material. Hence it does not lead to any modification of the surface.

Laser Annealing

Annealing marking is an oxidation process used on carbon containing metals by applying heat through laser on the surface of any metal. Annealing marking generally gives a black mark with a smooth finish, but the color may vary from brown, red to green etc. depending upon the heat used for marking.

Some key points of annealing:

Used on carbon-containing metals such as Titanium, Steel, Stainless Steel, Iron
Oxidation process can result in a variety of colors
A slower, more drawn-out process
Commonly carried out on products used in the medical industry. Its pplications include internal tracking and branding.

Carbon Migration Laser Marking

Carbon migration is another type of laser marking in which a metal or metal alloy is heated, causing the metal to chemically bond with its carbon molecules. This bonding brings the carbon properties to the surface of the material. When this occurs, it often resultsin a dark laser marking that can even be black. This type of marking is a faster process than annealing because it provides a high degree of heat to a smaller area within a more rapid time period.

Some of the key-points of carbon migration laser marking:

Only metals and their alloys containing carbon such as Steel, Stainless Steel, Carbide, Titanium can utilize this marking
Heating process helps carbon to migrate to the surface
Produces dark markings
Heat is applied rapidly

Foaming Laser Marking

Foaming is a laser marking technique used only on polymers. Laser foaming is carried out by creating a molten burn on the surface. The molten creates foaming gas bubbles. Foam laser marking is usually carried on a polymer and results in a light color.

Some of the key-points of Foaming Laser Marking:

Used only on polymers
Produces light & smooth markings
Material is melted, creating foam and gas bubbles

Coloration Laser Marking

Coloration laser marking is the process of adding color to a polymer or metal by controlling laser and scanner parameters such as pulse frequency, pulse width, power, speed and more. Coloration on polymer occurs through a process of foaming, whileon metals, it occurs through the process of oxidation.

Some of the key-points of Coloration Laser Marking:

Can be utilized for both metals and plastics
The process for coloration varies depending on the material to be marked
Creates contrast in both colored and black and white materials
Color results are based on an oxidation process

Markolaser supplies excellent European laser marking machine systems globally. All our laser marking machines are built with European laser marking machine building technology. The heart of laser marking machines is the laser marking machine generator which we import from Europe. the Galvos used in all our laser marking machines are imported from Germany. However, this does not mean that Markolaser laser marking machines are expensive. Our laser marking machines are built keeping affordability and quality in mind.

Basic questions about laser marking & engraving and their answers.

1 How is laser marking done ?

Ans. The laser beam of laser markers slightly alter the surface without evaporating it underneath, thereby inducing a colour change on the surface where the laser beam is focused. Laser marking is performed through various processes such as laser annealing, laser ablation, laser coloration and laser carbon migration. https://www.markolaser.com/industries/laser-marking-and-laser-hallmarking-by-markolaser

2 What is the difference between laser marking & laser engraving?

Ans. Laser marking is a superficial phenomenon where laser beams change the color of the material whereas laser engraving removes the material (by evaporation) up to the depth that is desired. depth.

3 Is there any chance of the product getting damaged after being subjected to laser beams?

Ans. Laser marking is a controlled marking process. There is a very slight loss of surface material when the laser beams mark, clean, ablate or color the surface. The product does not get damaged due to the regulated effect of laser beams on the surface of the product. The laser marks are permanent and do not fade unless they are scratched with sharp edges.

4 What is a Laser Marking Machine?

A laser marking machine essentially marks a product or a sample by various marking techniques such as engraving, foaming and annealing at different speeds and with different effects, depending upon the composition of the sample and its inherent light absorption properties.

5 What is a Fiber Laser Marking Machine?

6How much is a laser engraver?

7 How does a laser marking machine work?

Ans: During laser engraving (a marking scheme), the surface of the job/sample/work piece is melted and vaporized by the heat generated by the laser beam. This induces a change in the composition of the material at the point of the laser incidence. The gorges/crevices thus formed on the surface of the work-piece in this way reveal the final engraved result.

8 How is laser marking different from laser engraving?

Ans: Laser engraving is a subset of laser marking wherein the-piece upon which the laser is focused undergoes a change in composition by means of ablation and vaporisation of its laser incident area. Laser marking, however, involves several techniques under its umbrella of processes like engraving, annealing, foaming, staining etc.

9What materials can be laser engraved?

Ans: Materials that can be laser engraved/marked include Stainless steel, Aluminium, Brass, Bronze, Titanium, Silver, Gold, Ceramics, Polymers, Stone, Granite, Wood, Cork, Cardboard, Tiles, Glass among a few.

Frequently asked Questions?

1 What types of laser processes can be performed for jewelry manufacturing and hallmarking?

Ans: Markolaser systems support a wide range of jewelry manufacturing applications, including laser marking, engraving, deep engraving, and precision cutting. These capabilities enable BIS hallmark marking, logo engraving, serial number marking, seamless ring and bangle engraving, and intricate filigree cutting on gold, silver, platinum, brass, and other precious metals.

2 What is Foaming laser marking, and which materials can utilize it?

Ans: Foaming laser marking is a specialized process used primarily on plastic and polymer materials. The laser creates microscopic gas bubbles within a controlled molten surface layer, resulting in a smooth, raised, light-colored mark that provides excellent contrast against darker plastic backgrounds.

3 What unique engineering features allow Markolaser machines to safely achieve clean hallmarking?

Ans: Markolaser machines incorporate advanced engineering features such as built-in backlash protection to minimize the impact of reflected laser energy and protect critical optical components. Additionally, the systems are optimized for ultra-fine line quality, enabling sharp, high-precision hallmarks, certification marks, logos, and microscopic engravings with exceptional edge clarity.
