Laser Marking Definition

Laser marking is a versatile and precise technology used to create permanent markings on a variety of materials. Due to its speed and reliability, we advise using laser marking for the majority of marking applications.

What Is Laser Marking?

Laser marking utilizes a high-powered laser beam and creates marks on parts and products by melting their surface. These marks could be in the form of text, images, barcodes, numbers, or other identifiers.
In industrial and production operations, laser marking is a precise and versatile technique used for purposes like product branding, traceability, personalization, and aesthetics. It has a number of benefits, such as high precision, longevity, and versatility in marking a variety of materials, such as metals, plastics, ceramics, glass, and more.

How Does Laser Marking Work?

Laser marking works on the principle of localized material ablation that a powerful laser beam is used to selectively remove material off the surface of an object to create permanent marks. One feature unites all laser marking techniques: the laser beam is pulsed, providing quick bursts of energy at certain times. The material surface reflects the majority of the beam’s energy, but it also absorbs some of it and turns some of it into heat. Enough energy must be absorbed by the material for laser marking to take place in order to melt its microsurface and cause it to expand.
The material’s temperature rises as heat is generated from the energy of the beam. The surface becomes pliable at such a high heat, allowing it to change shape.

Various Metals’ Melting Points

MaterialMelting Point
Carbon Steel1415—1530°C
Aluminum 380536°C
Aluminum 6061580°C
Stainless Steel Grade 3041400—1450°C
Stainless Steel Grade 3161375—1350°C

Localized changes take place on the surface as the material melts and cools down in milliseconds. Surface irregularity varies and leaves permanent marks.

Is Laser Marking Permanent?

Yes, laser marking is considered permanent. This featured performance is one of the key advantages of laser markings. Unlike other types of marking, such as inkjet printing or labels, which might fade, wear off, or be readily erased, laser markings are deeply etched or engraved into the surface of the material. They are consequently very resistant to:

●  Abrasion: Even in high-friction conditions, laser marks are resistant to being scratched or worn away.
●  Chemicals: Laser marks are often resistant to contact with a variety of chemicals, such as acids and solvents.
●  Environmental Considerations: They are resilient to UV light, moisture, and temperature changes.
●  Modification: Without causing harm to the underlying material, it can be hard to change or delete laser markings.

Due to its durability and resistance to external influences, laser marking is widely utilized in fields where long-lasting, legible marks are required, including aerospace, automotive, electronics, and medical. It is a reliable process for branding, personalization, and traceability of products that guarantees the marks are identifiable and permanent for the duration of the product’s lifecycle.
