The laser marking machine industry has quietly developed for nearly 50 years. Everyone knows laser marking machines. However, most people are not very familiar with their characteristics. The following are some basic characteristics of laser marking machines.
The following knowledge points are listed below:
The hot process of the laser marking machine
The cold process of the laser marking machine
The advantage of the laser marking machine
The field that are using the laser marking machine
The application characteristics of the laser marking machine
The laser beam has a higher energy density (this is a concentrated energy flow), the surface treatment of the irradiated material, the surface of the material absorbs laser energy, and the thermal excitation process of the irradiated area causes the surface of the material (or coating) to rise in temperature and cause deterioration , Melting, ablation, evaporation and other phenomena.
Photons have high load energy, which can break the chemical bonds in materials (especially organic materials) or the surrounding medium, and cause non-thermal processing damage to materials. This cold processing is of special significance in laser marking processing, because it is not a thermal ablation, but cold peeling, breaking chemical bonds, will not have the "heat damage" side effect, so it will not affect the inner layer and nearby surface processing. Generates effects such as heat or thermal deformation. For example, in the electronics industry, excimer lasers are used to deposit a thin film of a chemical substance on a substrate and form a narrow groove in a semiconductor substrate.
The advantages of laser marking and engraving are: a wide range of applications, all kinds of substances (metals, glass, ceramics, plastics, leather, etc.) can be marked with permanent high quality. No stress on the surface of the workpiece, no mechanical deformation, no corrosion on the surface of the material.
The laser marking machine can be used on almost any material. Can be marked with permanent high quality. No stress on the surface of the workpiece, no mechanical deformation, no corrosion on the surface of the material.
Can be carved metal and various non-metallic materials. More suitable for some products that require precision and high precision.
Application industry: electronic components, integrated circuits (ICs), home appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses watches, jewelry accessories, auto parts, plastic buttons, building materials, PVC pipes, medical equipment and other industries.
Applicable materials: common metals and alloys (all metals, such as iron, copper, aluminum, magnesium, zinc), rare metals and alloys (gold, silver, titanium), metal oxides (various metal oxides), special surface treatments (Phosphating, aluminum anodizing, electroplated surface), ABS material (appliance casing, daily necessities), ink (transparent button, printed product), epoxy resin (electronic component packaging, insulation layer).
The laser marking machine has flexible processing methods, which can meet the needs of individual laboratory design and the requirements of industrial mass production. Laser engraving is fine, and the line can reach millimeter to micron level. It is very difficult to mark and modify the laser marking technology, which is very important for product anti-counterfeiting. Laser processing system and computer numerical control technology can efficiently automate processing equipment, can play a variety of text, symbols and patterns, easy to use software to design engraving patterns, change the label content, and meet the requirements of modern production with high efficiency and fast pace; laser processing has no pollution sources, It is a clean and pollution-free high environmental protection processing technology.
So, comparing to traditional way of marking, the laser marking machines have so many advantages, why not choose them? If you want to know more about Laser Cutting Machine, , CNC Wood Working Machine click here.
