Laser Cutting Technology: Revolutionizing the Leather Processing Industry

• Why is laser multi-layer cutting so important?

As economic output grows, labor, resources, and the environment have entered an era of scarcity. Therefore, the leather industry must eliminate high-energy-consuming and highly polluting production techniques and processes and widely adopt clean production and energy-saving technologies to achieve sustainable development. 

The leather industry has shifted from the age of commodities to the age of products. Consequently, the advanced technology of laser cutting and engraving leather is increasingly being applied in leather cutting for various purposes such as shoe materials, leather clothing, logo processing, embroidery, advertising decoration, wood processing, packaging printing, laser die-cutting, interior decoration, printing and hot stamping templates, and craft gift industries, among others.

Introduction of Two Different Leather Cutting Methods

 

• Traditional knife cutting leather technology:

Traditional leather cutting methods include punching and shearing. In punching, different shapes of cutting dies need to be made and used according to the specifications of different parts, resulting in a large demand and high cost for cutting dies. This, in turn, affects the variety of patterns, and there are also problems with long lead times for die production and difficulties in storage.

Additionally, during the cutting process using cutting dies, it is necessary to leave cutting clearances for consecutive cutting, leading to certain material waste. Based on an analysis of leather's material characteristics and the cutting process, shearing is more suitable. 

• Laser cutting/engraving leather technology:

Laser cutting leather offers significant advantages, such as small incisions, high precision, fast speed, no tool wear, ease of automation, and smooth cutting surfaces. The mechanism behind laser cutting leather involves vaporization cutting, especially when CO2 lasers are used, as leather materials have a high absorption rate for CO2 lasers. 

Under the action of the laser, the leather material is instantaneously vaporized, resulting in high cutting efficiency, making it more suitable for large-scale production.

Progress brought by laser cutting machines in the leather processing industry:

 

The use of laser cutting machines in the leather industry has overcome the problems associated with slow manual and electric shear speed, difficult typesetting, low efficiency, and significant material waste. The fast speed and easy operation of laser cutting machines have brought significant benefits to the development of the leather industry. Users only need to input the graphics and dimensions they want to cut into the computer, and the laser engraving machine will cut the entire material into the desired finished product based on the computer data. There is no need for cutting tools or molds, and at the same time, it saves a considerable amount of human resources.
