In our production and life, black products occupy many places. Laser marking machines are used as equipment with clear logos. Many netizens are worried that black products can be engraved because of their special materials. Can they be engraved for a long time? Today, I want to learn with you whether laser equipment can be marked on black products.

Generally speaking, a laser marking machine can carve black products. The laser beam of the equipment can be focused on the surface of the material and engraved or engraved the black mark on the object through physical and chemical reactions.

For metal materials, laser marking machines mainly achieve black marking through oxidation, reduction, ablation, etc. Under the irradiation of the laser beam, the oxide layer on the metal surface changes to form a black oxide, leaving black marks.

For non-metallic materials, such as plastics, rubber, etc., laser marking machines mainly achieve black marking through carbonization, thermal discoloration, etc. Under the action of the laser beam, these materials will be carbonized by high temperatures to form black marks.

In order to obtain better engraving effects, producers of black products will also consider the need for laser marking during the production process. For example, when selecting materials, materials with higher laser absorption and softer texture will be selected. In addition, pretreatment will be carried out on the surface of the product, such as applying special coatings or films, to improve the absorption of the laser and reduce damage to the product.

In general, laser marking machines can carve black products. However, to achieve this goal, many factors need to be considered, including the material, texture, surface condition of the product and the performance parameters of the laser marking machine. In practical applications, adjustments and optimization need to be made according to specific conditions to achieve better carving effects.
