Laser technology is currently widely used in the shoemaking and leather industries. The advantage of laser is that it can quickly engrave and hollow out various patterns on various leather fabrics, and it is flexible in operation without causing any deformation of the leather surface to reflect the color and texture of the leather itself. It also has many advantages such as high engraving precision, hollowing out without burrs, and arbitrary shape selection. It is suitable for the needs of processing and manufacturing manufacturers of shoe uppers, shoe materials, leather goods, handbags, luggage, leather clothing, etc.
