The application of ZHHIMG brand granite in battery laser marking equipment: What are the advantages of the base
In the field of new energy battery manufacturing, laser marking, as a key process that determines the performance and safety of batteries, poses strict requirements for equipment stability. ZHHIMG brand granite, with its outstanding physical and chemical properties, has become the preferred material for the base of battery laser marking equipment. With high-precision and high-stability solutions, it helps enterprises break through production bottlenecks and enhance product competitiveness.
Ultra-low coefficient of thermal expansion: The "Stabilizing anchor" against temperature fluctuations
When the laser marking equipment is in operation, factors such as the heat generated by the laser and mechanical transmission friction can cause significant changes in the internal temperature of the equipment. The dimensional deformation of common materials under temperature fluctuations will directly affect the laser focusing accuracy and the accuracy of the scribing trajectory. The thermal expansion coefficient of ZHHIMG brand granite is as low as (4-8) ×10⁻⁶/℃, which can effectively suppress thermal deformation during the long-term continuous operation of equipment. For instance, under the working condition of a temperature change of 10℃, the deformation of the 1-meter-long ZHHIMG granite base is only 40-80 nanometers, which is almost negligible. This ensures that the laser beam always precisely acts on the surface of the battery electrode sheet, avoiding defects such as line deviation and uneven depth caused by thermal deformation, and significantly improving the product yield.
Outstanding anti-vibration performance: A "natural barrier" to eliminate vibration interference
The environmental vibrations generated by the operation of other equipment and the movement of personnel within the factory, as well as the mechanical vibrations caused by the high-speed movement of the laser head, can all interfere with the marking accuracy. The density of ZHHIMG granite reaches 2.6-2.8g /cm³, and its hardness is as high as 6-7 on the Mohs scale. The internal mineral crystal structure endows it with excellent damping properties, with a damping ratio of 0.05-0.1, which is 5-10 times that of ordinary metal materials. In practical applications, when external vibrations are transmitted to the granite base, it can attenuate the vibration amplitude by more than 90% within 0.5 seconds, effectively isolating the influence of vibrations on the laser optical path and ensuring the smoothness and consistency of the marked lines. After a certain battery manufacturing enterprise adopted the ZHHIMG granite base laser marking equipment, the yield rate of electrode sheet marking increased from 85% to over 95%.
Chemical stability and zero pollution: The "Safety Guardians" Ensuring Process Purity
The battery production environment has extremely high requirements for cleanliness. Any pollutant may affect the performance and lifespan of the battery. ZHHIMG granite is mainly composed of minerals such as quartz and feldspar. It has stable chemical properties and is resistant to acid and alkali corrosion. When it comes into contact with chemical substances such as electrolytes and laser protective gases, it will not undergo chemical reactions or release harmful substances. Meanwhile, its dense structure (porosity < 0.1%) enables it to generate almost no particulate debris, meeting the ISO Class 1 cleanroom standard for battery manufacturing workshops. Unlike metal bases that may cause metal ion contamination due to corrosion, the ZHHIMG granite base provides a pure environment for the laser marking process, reducing risks such as battery short circuits and self-discharge, and enhancing product quality and reliability.
High-precision processing adaptability: Laying a "reliable foundation" for precision manufacturing
Laser marking equipment requires positioning accuracy at the micrometer or even nanometer level, which poses extremely high demands on the processing accuracy of the base. Relying on advanced processing technology, the ZHHIMG brand can control the flatness of the granite base within ±0.5μm/m and the surface roughness Ra≤0.05μm, providing precise installation references for core components such as laser heads and precision guide rails. Through ultra-precision grinding and polishing processes, the ZHHIMG granite base can perfectly meet the high-precision requirements of high-end laser marking equipment, ensuring the long-term stable operation of the equipment and reducing the frequency of equipment calibration and maintenance caused by insufficient base accuracy.
Long lifespan and high cost performance: The "core partner" to help enterprises reduce costs and increase efficiency
The ZHHIMG granite base features excellent fatigue resistance and aging resistance. Under normal usage conditions, its service life can reach over 20 years and it requires no frequent maintenance. Compared with metal bases that may shorten the service life of equipment due to fatigue cracks, corrosion and other issues, ZHHIMG granite bases significantly reduce the equipment replacement and maintenance costs for enterprises. In the long term, its high cost-performance advantage is significant, helping battery manufacturing enterprises improve production efficiency while effectively controlling production costs and enhancing market competitiveness.
The ZHHIMG brand granite, with its comprehensive advantages in thermal stability, vibration resistance, chemical stability, processing accuracy and economy, provides all-round performance guarantee for battery laser marking equipment. Against the backdrop of the rapid development of the new energy industry, the ZHHIMG granite base is becoming a key force driving battery manufacturing towards higher precision and efficiency.
