Custom engraving6/19/2023 ![]() Whereas laser etching melts the material surface to change its roughness, laser engraving sublimates the material surface to create deep crevices. ![]() There’s also a unique method called laser annealing to mark metals like stainless steel. You can laser etch a wider variety of materials, including steel, aluminum, anodized aluminum, lead, magnesium, and zinc. ![]() Those treatments can include shotblasting, e-coating and heat treatments, addressing the most complex traceability issues.īut if engraving the most resistant identifiers isn’t needed, laser etching is generally preferred because it’s a high-speed method that doesn’t rely as heavily on ablation. The most outstanding feature of this process is its ability to engrave 2D codes that keep high readability rates after post-process treatments. Metal engraving works with steel and aluminum (including anodized and die-casting aluminum). Laser engraving technology is typically used to engrave metal workpieces that will be exposed to various types of wear or surface treatments. The material being marked: its compatibility with the marking method. ![]() The laser marking speed: the marking time that prevents production bottlenecks.The marking’s resistance: its capacity to remain legible under harsh conditions.To choose the right laser marking process, you should rely on three factors: Should You Choose Laser Engraving or Laser Etching?
