Even though you may be relatively new to the process of iron copper plating, you must have seen or used products processed by this process in your life. This is a process of covering the surface of iron or steel with a layer of copper, which can improve the corrosion resistance, electrical conductivity, decorative and welding properties of the material.
Copper-plated iron surface is a composite material consisting of an iron substrate and a copper overlay, which has the advantages of high strength, wear resistance and electrical conductivity and is commonly used in electronic components, motor parts, electromagnetic shielding, etc. Laser marking on the iron-plated copper surface can realize the functions of identification, traceability and decoration of the product and improve the added value and market competitiveness of the product.
Difficulties that may be encountered in laser marking on the surface of iron-plated copper:
If the laser power is too high or the speed is too slow, it may cause excessive melting or ablation of the copper cladding, affecting the marking quality and accuracy.
If the laser power is too low or the speed is too fast, it may lead to incomplete removal or color change of the copper cladding, reducing the marking contrast and readability.
So, laser control is the key to marking on copper-plated iron surfaces!
Therefore, when laser marking on copper-plated iron surfaces, it is necessary to select the appropriate laser type, wavelength, pulse width and frequency parameters according to the material characteristics and marking requirements.
The characteristics of laser marking on iron-plated copper surface are non-contact processing, high applicability and excellent results, but there are also certain difficulties, mainly to control the laser parameters in order to achieve the ideal marking effect.
UV lasers can achieve "cold marking", i.e., marking materials without heat-affected areas, which is suitable for applications requiring high precision and clarity. UV lasers can produce high quality micro-engraving and color variations on copper-plated iron surfaces for applications requiring high detail and aesthetics.
