Along with the progress of society and the development of science and technology, leather products are being more widely used in various applications. Leather products not only create infinite value, but also play an indispensable role in daily life, such as for clothing, shoes, gloves, sandals, fur hats, belts, watch straps, leather cushions, car seats, and steering wheel covers. Traditional technology for leather processing mostly adopts cutting, embossing, and embroidery machines, which operate at slow speeds and have a high manpower cost with sometimes less than high-quality results. As a consequence, this fundamentally restricts the development of the leather industry. In recent years, because of the wide application and popularization of lasers, leather laser cutting machine use also rose at this time. High-energy, high-power-density carbon-dioxide (CO2) laser beams can process leather rapidly, efficiently, and continuously. Laser cutting machines employ digital and automatic technology, which provides the capability to hollow out, engrave, and cut in the leather industry. An example is the leather laser cutting/engraving machine by Hunst Laser Technology (Dongguan, Guang...
