Leather is a high-quality material that has been used for centuries. Leather has been used for many purposes in history, but it also exists in modern manufacturing processes. Laser cutting is one of many methods to produce leather design. Leather has proved to be a good medium for laser cutting and engraving. This paper introduces a non-contact, fast and high-precision laser system for leather cutting.
With the progress of society and the development of science and technology, leather products are more and more widely used. Leather products play an indispensable role in daily life, such as clothing, shoes, bags, wallets, gloves, sandals, leather hats, belts, watch bands, leather cushions, car seats and steering wheel covers. Leather products are creating unlimited commercial value.
Increasing popularity of laser cutting
In recent years, due to the wide application and popularization of laser, the use of leather laser cutting machine is also rising at this time. Carbon dioxide (CO2) laser beam with high energy and high power density can process leather rapidly, efficiently and continuously. The laser cutting machine adopts digital and automatic technology, providing the leather industry with the ability of hollowing, carving and cutting.
The advantages of using CO2 laser cutting machine in the leather industry are obvious. Compared with the traditional cutting method, laser cutting has the advantages of low cost, less consumption, no mechanical pressure on the workpiece, high precision and fast speed. Laser cutting also has the advantages of safe operation, simple maintenance and continuous processing.

Working principle of laser cutting
The CO2 laser beam is focused into a small spot, so that the focus reaches high power density, and the photon energy is quickly converted into thermal energy to vaporize, forming holes. When the light beam moves on the material, the hole will continuously produce narrow cutting seams. This kind of cutting seam is little affected by residual heat, so no workpiece deformation will occur.
The size of the laser cut leather is consistent and accurate, and the cut can be any complex shape. Using computer graphics to design patterns can achieve high efficiency and low cost. Due to the combination of laser and computer technology, users can design on the computer to realize laser engraving output and change engraving at any time.
The customer manager of a shoe factory in laisai said that in the past, the company used to use a mold knife to cut shoe molds and carve patterns, and each style required a different mold. The operation is very complicated and it is impossible to handle small and complex pattern design. Since the purchase of laser cutting machine from Wuhan Jinguang laser Co., Ltd., laser cutting has completely replaced manual cutting. Now, the leather shoes produced by the laser cutting machine are more exquisite and beautiful, and the quality and technology have been greatly improved. At the same time, it greatly improves the production efficiency, especially suitable for the production of small batch orders or sometimes customized products.
Leather laser cutting
The leather industry is undergoing a technological revolution. The special laser leather cutting machine breaks the low speed and typesetting difficulties of traditional manual and electric plate shears, and comprehensively solves the problems of low efficiency and material waste. In contrast, the laser cutting machine is fast and easy to operate. It only needs to input the graphics and dimensions into the computer. The laser cutting machine cuts the whole material into finished products without tools and molds. Using laser cutting to realize non-contact machining is simple and fast.
CO2 laser cutting machine can perfectly cut leather, synthetic leather, polyurethane (PU) leather, artificial leather, suede leather, brushed leather, microfiber, etc.
Laser cutting machine has been widely used. CO2 laser can cut and engrave textiles, leather, plexiglass, wood, MDF and other non-metallic materials. In terms of shoe materials, the precision of laser cutting machine is easier to make complex designs than manual cutting. Since the laser vaporizes and burns materials for cutting, smoke is inevitably generated, so the machine needs to be placed in a well ventilated area and equipped with a dedicated exhaust system.
