The Principle And Advantages Of Laser Resistance Trimming
The principle of laser processing is basically the same as that of the convex lens converging sunlight to ignite a match. The laser emitted by the laser undergoes a series of treatments, and after being focused by the lens, the energy is highly concentrated in a small range. If the processed material absorbs the laser well, the material in the irradiated area will be absorbed The energy of the laser heats up rapidly.
Depending on the properties of the material (such as melting point, boiling point, and temperature at which chemical changes occur), the workpiece will undergo a series of physical or chemical changes, such as melting, gasification, oxide formation, discoloration, etc. This is the principle of laser processing .
The Advantages Of Laser Processing
Advanced processing mode and high efficiency
The focused very fine laser beam is like a tool, which can remove the material on the surface of the object point by point. Its advanced nature is that the marking process is non-contact processing without mechanical extrusion or mechanical stress, so it will not damage the processed items; due to The laser focused size is small, the heat-affected area is small, and the processing is fine. Therefore, some processes that cannot be achieved by conventional methods can be completed.
Low cost, fully automatic, easy to operate
The “tool” used in laser processing is a focused light spot, and no additional equipment and materials are required. As long as the laser can work normally, it can be continuously processed for a long time. The laser processing speed is fast and the cost is low. The laser processing is automatically controlled by the computer, and no human intervention is required during production.
Easy product identification
After laser marking, since the surface material is peeled off, the marking will not fade due to harsh environments, and its information can be maintained permanently. Laser can mark unique serial numbers for products, which is convenient for product identification and traceability. It is difficult to imitate the special effect of laser marking by traditional technology, so laser marking has outstanding performance in anti-counterfeiting.
Meet environmental requirements
Laser processing is non-toxic and harmless, and the processed products exceed the production and environmental protection requirements of various countries. It is a safe and clean processing method. Customers do not need to worry about export restrictions due to silk screen printing and corrosion processes.
Achieve zero backlog
Laser processing is flexible and easy to change. Marking products according to the orders of different customers can effectively avoid the differentiated production of the same product and reduce the risk of product backlog.
