Abstract:

Laser engraving of elements for injection molds is a technology that allows precise and durable engraving of various details on the surface of the molds. This method uses a focused laser beam to remove material from the mold surface, creating high-resolution patterns, text or codes. This study investigates the influence of various parameters on the laser engraving process, utilizing factorial experimental design to systematically analyze their effects. The parameters considered include power, speed, frequency, number of cuts, stepover, focal distance, and engraving strategy. The objective function of the study is the processing time, which is critical for optimizing efficiency in laser engraving applications. By employing a factorial approach, we aim to identify the interactions between these factors and their collective impact on processing time. The results indicate that certain parameters significantly affect the engraving efficiency, providing insights into optimal settings for enhanced performance. This research contributes to the understanding of laser engraving dynamics and offers practical guidelines for practitioners seeking to improve operational efficiency in laser-based manufacturing processes. Due to the high precision, and flexibility, laser engraving allows the creation of fine and very complex details with high efficiency and durability.
