Laser Etching

Image ID: 6.5.001DP

Laser Etching is a subtractive process where high heat from the laser beam removes minimum unwanted material to obtain the desired design. The typical engraved depth is less than 0.025mm.

  • Ideal for bar codes, UID codes, QR codes, logos and other identification needs
  • Suitable materials like bare, anodized or plated metal surfaces, as well as polymers and ceramics
  • Applicable markets: Medical, industrial manufacturing

Everyday Queries About Laser Etching Services

Laser etching can be performed on various materials, including:

– Metals (such as stainless steel, aluminum, brass)
– Plastics (acrylic, ABS, polycarbonate)
– Wood
– Glass
– Leather
– Stone
– Coated surfaces (e.g., anodized aluminum)

Different materials interact with the laser beam in unique ways, leading to variations in the appearance and depth of the etched mark.

Laser etching involves creating marks or designs on the surface of a material without cutting all the way through, while laser cutting involves cutting completely through the material along a predefined path. Laser etching is a surface treatment that alters the appearance of the material, whereas laser cutting physically separates the material along the cutting line.

Laser etching can create color effects on certain materials. For example, when laser etching anodized aluminum, the process can reveal different colors beneath the surface oxide layer, resulting in colorful markings. Additionally, some plastics or coated materials may exhibit color changes or contrasts when etched with a laser.

Laser etching creates permanent marks on materials by altering the surface layer through heat or vaporization. The marks are typically durable and resistant to fading, smudging, or wear over time, making laser-etched designs long-lasting and resilient.

Several factors can affect the quality and appearance of laser etching, including:

– Laser power: Higher power lasers can produce deeper and more pronounced marks.
– Speed and frequency: Adjusting the speed of the laser beam and its pulsing frequency can impact the quality and speed of the etching process.
– Material type and color: Different materials react differently to laser etching, leading to variations in contrast, depth, and appearance.
– Focus and beam properties: Proper focusing of the laser beam and control of its spot size are crucial for achieving sharp and detailed etchings.
– Design complexity: The intricacy of the design or pattern being etched can also influence the clarity and quality of the final result.

Laser etching is well-suited for mass production, especially for tasks that require consistent and high-quality markings on a large number of items. The automation and precision of laser etching technology make it efficient for producing customized or standardized marks on industrial parts, products, or components.
