Laser marking technology is widely used in the printing industry for a variety of materials such as plastic and rubber, metal and silicon chips. Compared with traditional mechanical engraving, chemical etching, screen printing and ink printing, laser marking has the characteristics of low cost and high flexibility, which can be controlled by computer system. Laser engraving on the workpiece surface is permanent.
At present, in the marking and printing industry, laser marking has occupied 90% of the market, which is attributed to the following eight advantages:
1. Permanent:
Marks will not degrade due to environmental factors (such as contact, acidic or alkaline gases, high or low temperature, etc.).
2. Anti-counterfeiting:
The marks engraved by laser marking technology cannot be easily counterfeited or altered to a certain extent.
3. Non-contact:
Laser marking is performed with a non-mechanical "light knife" and can mark any surface, regular or irregular. The marked parts will not be qualitatively changed, thus ensuring the original accuracy of the parts. It neither corrodes the work surface nor wears down the "cutting tool" without any poison or contamination.
4. Wide range of applications:
Lasers are suitable for the processing of many metallic and non-metallic materials such as aluminum, copper, iron and wood products.
5. High engraving precision:
The pattern of the items engraved by the laser marking machine is more delicate, the minimum line width can reach 0.04mm, and the marking is clear, durable and beautiful. Laser marking can meet the needs of printing large amounts of data on smaller plastic objects, such as QR codes that require high precision and high definition. Compared with stamping or spray marking, it has strong market competitiveness.
6. Low operating cost:
The marking speed is fast, only one marking is required, and the operation cost is low. Although the investment cost of laser marking equipment is higher than that of traditional equipment, from the perspective of operating costs, the cost of laser marking machines is much lower.
7. High efficiency:
The laser beam controlled by the computer can move at high speed (up to 5~7 m/s) and can complete the marking in seconds.
8. Rapid development:
Combining laser and computer technology, users can realize laser printing output through computer programming, and can change the printing design at any time, which fundamentally replaces the traditional module manufacturing process, and provides convenience for shortening the product upgrade cycle and providing flexible tools in the manufacturing industry. .
