Heat Transfer Heat transfer in laser engraving refers to the process by which thermal energy is transferred from the laser beam to the material being engraved. During engraving, the laser beam interacts with the material surface, generating heat that causes localized melting, vaporization, or chemical changes. Efficient heat transfer is essential for achieving desired engraving results while minimizing adverse effects such as material deformation, discoloration, or heat-affected zones. Various factors, including material properties, laser parameters, and cooling methods, influence the heat transfer dynamics and ultimately determine the quality and precision of the engraved markings. |
