Cast Metal Laser Marking: Permanent Coding on Rough Surfaces and Parameter Optimization
Cast metal laser marking is an advanced industrial marking method used to create permanent and readable marks on parts with rough and heterogeneous surfaces. Cast iron, cast aluminum, and other alloys require different parameters compared to standard marking applications due to their surface structure. Thanks to fiber laser technology, serial numbers, DataMatrix, and QR code marking can be applied on these surfaces with high contrast. This guide explains in detail laser marking techniques, challenges, and solution methods for cast metal surfaces.
Laser Marking Technology on Cast Metal Surfaces
What is cast metal?
Cast metals are produced by pouring molten metal into molds. This production method creates a porous and rough structure on the surface.
Surface roughness
The surface of cast parts is generally not smooth. This condition may affect marking contrast.
Use of fiber laser
The most commonly used technology for cast metal marking is fiber laser systems.
Contrast creation
Laser parameters must be carefully adjusted to create contrast on rough surfaces.
Deep marking
On cast surfaces, the deep engraving method is generally preferred.
Marking precision
Due to the surface structure, micro precision may not always be possible.
Serial number marking
Serial numbers and product information can be processed on cast parts.
QR code and DataMatrix
2D code marking is possible, but surface quality plays an important role.
Surface preparation
In some applications, cleaning the surface can improve marking quality.
Industrial application areas
- Automotive cast parts
- Machine components
- Industrial equipment
- Heavy industry parts
