Why is the laser marking machine not clear when printing purple copper?

For laser marking machines, the marking effect is closely related to the characteristics of the material. In general, laser marking machines can clearly mark various metal materials, but there may be some problems when marking purple copper.
For materials like copper, due to its high thermal conductivity, heat is quickly absorbed and transferred to the surrounding materials during laser marking, resulting in blurred marking lines. In addition, copper is also prone to oxidation, which can lead to poor marking effect.

How to solve the problem of unclear marking of purple copper by laser marking machine?
To address the issue of unclear marking of purple copper by laser marking machines, the following measures can be taken:
1. Adjust the frequency and power of the laser marking machine
By adjusting the frequency and power of the laser marking machine, it can make it more stable and clear when marking purple copper.
2. Change the marking position and angle
When marking red copper, it is possible to try changing the marking position and angle to reduce the thermal conductivity of the copper and make the marking lines clearer.
3. Use the corresponding marking solution
When marking purple copper, the corresponding marking solution can be used to improve the clarity of the marking. Usually, marking solution can reduce material reflection, improve light absorption, and enhance oxidation prevention ability, thereby improving the marking effect.
By using the above methods, the problem of unclear marking of purple copper by laser marking machines can be solved, and a clearer and more beautiful marking effect can be achieved.
