The utilization of laser engraving machines within the leather industry has resolved issues related to slow traditional manual and electric shear speeds, intricate typesetting, low efficiency, and significant material wastage. The swift pace and straightforward operation of these machines have profoundly benefited the leather industry’s advancement. With a laser engraving machine, all that is required is to input the graphics and dimensions into the computer, and the machine will accurately cut the material accordingly. This method eliminates the need for tools or molds, thereby saving a considerable amount of labor resources.
Consequently, laser engraving machines are extensively employed in the leather industry, often referred to as laser punching, particularly for applications such as uppers, handbags, leather gloves, and bags. This process involves punching, surface hooking, or cutting patterns. Compared to traditional cutting methods, laser engraving offers numerous advantages: the edges of the cut leather remain untainted, with automatically sealed or rolled edges, ensuring no deformation or hardening, precise and consistent sizing, capability to cut intricate shapes, high efficiency, and low cost. Computer-designed graphics enable the cutting of lace in any shape or size without mechanical pressure on the workpiece, ensuring safe operation and simplified maintenance.
By combining laser technology with computerized design, users can easily create and modify patterns, thereby realizing their product concept efficiently. The introduction of laser engraving machines has significantly propelled the leather industry’s progress.
The laser engraving process demands certain criteria: the surface hook lines must remain unblemished, the engraved material background should maintain its color, and the leather cutting edges must not darken while ensuring clear engraving.
Laser engraving machines are suitable for various materials including synthetic leather, PU leather, PVC artificial leather, genuine fur, semi-finished products, and an array of leather fabrics. Engraving speeds vary depending on the size of the graphic, with smaller patterns requiring slower drawing line speeds (approximately 0.8m/points) and larger patterns necessitating cutting speeds ranging from 1.5 to 3m/points, with light intensity set at 75%. Leather cutting is slightly slower, with speeds ranging from 0.4 to 1.2m/points and light intensity varying between 60% and 75%.
