With the maturity of $↑✘laser marking technology,€♥₩ε more and more companies ‌↕&have chosen a new type of marking eqσ♠εuipment-laser marking §≤γmachine with clear marking, h&<igh processing efficiency, simε§≈☆ple operation, environmental protection↔÷¥, no consumables, and permanent ♦πmarking. However, many friends do not <λ&know much about the principle andσ→ performance of laser marking machin♠¶™¶es. Recently, a netizen left a messa€♣✘ge on our company's  λεDouyin（抖音(yīn)名：佛山(shān)富蘭激光(guā¥←™ng)） and asked: Does laser marking ∏€÷damage the surface of the pro¥÷☆¶duct?

Today, Foshan Fulan Laser wilφ₹≤↓l tell you whether laser marking  ®will damage the surface of the prod  <uct.

The effect of laser markin÷&βg is to mark indelible marks on the surσ∞φface of various materials ¥←with a laser beam. The effec€★t of marking is to expose•☆§↕ the deep material through the evaporaδ₽∞™tion of the surface ma±♦terial, or to "carve" traces through thקe chemical and physical changes∞<φ of the surface material caused b≈♥y light energy, or to burn off p↕™‍♥art of the material thro× λ®ugh light energy to show the required ♦​etching Patterns, text.

The principle of laser marking prε¥ocessing: the laser emitted by t↓•¥he laser undergoes a series of tre¶©atments, and the energy is co₽φ™ncentrated in a small range after ♦φ‍ focusing by the lens, sσ↔<o that the surface material is in∞δstantly melted, or even vapo γ→&rized, by controlling the ♠♠laser on the surface of t↔¥he material. Path to form the requiα'©red graphic mark.

According to different mate✔σ∑rial properties (such a≥♥s melting point, boili₹↕₩↕ng point, temperature at which↕  chemical changes occuσ"✘r), the workpiece wi≠•ll undergo a series o€∑f physical or chemical c¥♦hanges, such as melti¶₽☆ng, vaporization, oxide formation, λ​discoloration, and so on. This is the​↔ principle of laser proc<✔essing.

Laser processing mode: The focused £♦πlaser is like a very thin i✘÷βσnvisible tool, which v₹"aporizes the surface of the localγ≤λ area of the object poinδ​↑t by point. It is char ≤φ♦acterized by non-contact p ÷δ→rocessing, no contactλα< with the workpiece, no me♥§βchanical extrusion or Mechanical stres♥δs, therefore, will not change 'δ the physical properties of the proce¥↕ssed items.

Therefore, whether laser mark→β≈ing will damage the surface ☆$'₹of the product depends© ‍₽ on the material of the p₽☆&roduct, the model used, and th÷σe marking requirements. For exam ☆≤ple: glass crystal inner carving, ‍•↑βaluminum oxide shallow blackeninβπ<g, some plastics are marked with a UV₹₹δ♦ laser marking machine, etc. Th₽σΩ‍e surface of the marking is smoφ≥​oth, and it will not damage the s₽↕₹∑urface of the product; if deep ma÷★rking is required, the laser bππεeam is like carving The knife wo®↑α'rks on the surface of☆‌≤ the product, and the marking con↑α↔πtent will have a certaiλ☆₹n depth, which will damage€β§ the surface of the produ<₹ct to a certain extent, but the ©↔damage is very slight.
