Product Characteristics Of Laser Marking Machine

Release date:2015-09-19Views:6791

Two kinds of theories are generally accepted:"Hot working" with a high energy density of laser beam (which is the concentrated energy flow), irradiation on the surface of the material, the material surface to absorb the laser energy, in the irradiated area to produce thermal excitation process, so that the material surface (or coating) temperature rise, resulting in a change, melting,ablation and evaporation. The phenomenon of.

"Cold working" (highly ultraviolet) photons with high energy loading can disrupt the material (especially organic material) or the chemical bonds in the surrounding medium, causing the material to undergo non thermal processes. This cold is of special significance in the laser marking process, because it is not thermal ablation, cold strip break chemical bonds but does not produce heat damage, side effects, and thus on the machined surface layer and the nearby area does not produce heat or thermal deformation etc.. For example, in the electronics industry, excimer lasers are used to deposit chemical thin films on the base material and narrow slots on the semiconductor substrate.

Comparison of different labeling methods

Compared with the ink jet marking method, laser marking engraving has the advantages of wide range of applications, many kinds of materials (metals, glass, ceramics, plastics, leather and so on) can be permanently labeled with high quality. No force on the surface of the workpiece, no mechanical deformation, the surface of the material does not corrode.

Product application

A variety of non-metallic materials can be carved. Used for clothing accessories, pharmaceutical packaging, wine packaging, building ceramics, beverage packaging, fabric cutting, rubber products, shell nameplate, craft gifts, electronic components, leather and other industries.

May engrave metal and many kinds of nonmetallic materials. More suitable for some demanding precision, high precision products processing.

The application in electronic components, integrated circuit (IC), electrical appliances, mobile phone communications, hardware, tool accessories, precision instruments, watches, jewelry accessories, auto parts, plastic buttons, building materials, PVC pipe, medical equipment and other industries.

Including the applicable materials: ordinary metals and alloys (iron, copper, aluminum, magnesium, zinc and other metal), rare metals and alloys (gold, silver, titanium), metal oxide (metal oxide can), special surface treatment (phosphate, aluminum anodizing, electroplating, surface material (ABS) electrical appliances housing, commodity), ink (keypad, printing), epoxy resin (electronic components packaging, insulation layer).
