Laser cutting of flexible materials

Author:QINSUN Released in:2023-12 Click:47

Flexible materials are a relatively broad category. Textiles with exquisite patterns and complex textures, rubber with wear resistance, flexibility and strength, and plastics with convenient shaping and wide applications all belong to the broad category of flexible materials. The cutting of flexible materials is also a relatively broad topic, and different flexible materials will face different difficulties during processing.

For example, in fabric cutting and pattern processing, due to its soft and easily deformable characteristics, contact mechanical processing is used, and deformation under fabric stress is prone to errors. At the same time, there is a possibility of burrs or damage to the fabric during mechanical cutting. Due to the low ignition point of fabrics, if plasma cutting is used for processing, it is easy to cause thermal shrinkage around the chemical fiber cutting pieces at high temperatures, resulting in adhesion, reduced size, and even burning or discoloration, which affects the overall appearance.

Laser cutting can effectively avoid the above-mentioned problems. Laser cutting of flexible materials is the use of high-energy laser beams to instantly heat the material, causing local areas to melt or vaporize, thereby achieving the purpose of cutting.

Due to the lack of mechanical pressure from laser on fabric processing, there is no need to consider the issue of extrusion deformation. Cutting can achieve precision, reliability, and size standards, with no burrs or loose threads in the incision, and can achieve complex and fine fabric structures;

The laser has excellent focusing ability and can achieve cutting at the micrometer level, so the impact of high temperature will not diffuse, which can avoid the problem of yellowing and hardening of the fabric, while also ensuring the smoothness and accuracy of the cutting edges.

In addition, traditional cutting and cutting equipment has a relatively long design and production cycle during processing. For laser cutting, software layout can be directly used and completed in one step. Many layout software support multiple automatic layout functions, and the feeding and receiving process is brief, meeting personalized customization needs.

Due to the consideration of preventing fabric displacement, mechanical cutting often only allows for single-layer cutting. Laser cutting can achieve multi-layer parallel processing and automatically cut fabrics into units of different shapes and sizes according to requirements. If it is necessary to modify the corresponding design in batches, it is very troublesome for traditional cutting, while laser cutting can be combined with visual recognition systems to easily complete the process. At the same time, laser cutting equipment can also be integrated with processes such as dispensing and marking on the same laser equipment, saving redundant production processes.

Due to the aforementioned advantages, lasers have been widely used in many fields of flexible materials. In the textile industry, laser cutting can accurately process textiles of various materials, such as silk, nylon, leather, chloroprene rubber, polyester, cotton, etc. It can achieve high-quality cutting and stitching, whether used in clothing or household products. In the rubber product industry, laser cutting can be used to cut sealing rings, rubber gaskets, etc., improving the accuracy and quality of products. In the plastic products industry, laser cutting can be applied to the cutting and processing of plastic sheets, pipes, molds, etc. In addition, laser cutting of flexible materials can also be applied in fields such as automotive interiors, electronic products, medical devices, etc.

We hope that laser cutting can adapt to more flexible materials, and we also look forward to the emergence of more cutting equipment that can adapt to the characteristics of flexible materials.
