Laser Marking Techniques:
Etching, Marking, and Engraving
Laser marking is a versatile and precise process that can be used to create permanent markings on a wide variety of materials, including metals, plastics, wood, and glass. It is a highly efficient and environmentally friendly alternative to traditional marking methods such as hot stamping and engraving.
Etching
Etching is a laser marking technique that involves melting or ablating the surface of a material to create a shallow, textured mark. The depth of the mark is typically less than 0.1 mm, and it can be applied to both reflective and non-reflective materials. Etching is a good choice for applications where a high contrast mark is desired, such as identification plates and labels.
​
Advantages of Etching:
-
Creates high contrast marks
-
Suitable for both reflective and non-reflective materials
-
Fast and efficient process
-
Can be used on a wide variety of materials
​
Disadvantages of Etching:
-
Not as durable as other laser marking techniques
-
Can create a textured finish on some materials
Marking
Marking is a laser marking technique that involves changing the surface color of a material to create a visible mark. This can be done by either melting or ablating the surface material, or by inducing a chemical reaction that changes the color of the material. Marking is a versatile technique that can be used to create a wide variety of marks, including text, logos, and barcodes.
​
Advantages of Marking:
-
Can create a wide variety of marks
-
Durable and long-lasting marks
-
Suitable for a wide variety of materials
​
Disadvantages of Marking:
-
It is a longer process then the other techniques
Engraving
Engraving is a laser marking technique that involves removing material from the surface of a material to create a deep, permanent mark. The depth of the mark can be controlled to create a variety of effects, from shallow engraving for identification to deep engraving for decorative purposes. Engraving is a good choice for applications where a high degree of durability is required.
​
Advantages of Engraving:
-
Extremely durable and long-lasting marks
-
Can create a variety of effects, from shallow to deep engraving
-
Suitable for a wide variety of materials
​
Disadvantages of Engraving:
-
Slow process
-
Not as efficient as other laser marking techniques
-
Material might bend if its not thick enough
