How do you evaluate the laser power and speed?
When assessing the efficiency of a CO2 laser marking machine, one has to consider the quality of marking, efficiency, loading, and materials compatibility. The following are some of the essential considerations:
- Material Properties
Different materials require specific laser power and speeds. For instance:
-
-
- Metals such as stainless steel are harder, therefore, require greater laser power and slower marking speeds to engrave or mark deeply.
