Why use laser cutting technology for thin films

Thin film is a thin, soft, transparent film. It is made of plastic, adhesive, rubber or other materials. The scientific explanation of thin film is: a two-dimensional material formed by the deposition of atoms, molecules or ions on the surface of a substrate. Such as: optical film, composite film, superconducting film, mobile phone explosion-proof film, polarizer, plastic film, etc. Thin films are widely used in electronics, machinery, printing and other industries. Today we will discuss the process of Thin film laser cutting.

Thin film products usually need to be split after production to obtain the required subsequent products. In traditional processing and production, the cutting of thin film semi-finished products uses mechanical stamping. There are many problems with mechanical stamping and cutting, such as the easy loss of stamping convex and concave dies, the inconvenience of stamping and cutting products, and the easy occurrence of burrs or tears during cutting, which leads to low production efficiency, low product output, and requires a lot of labor.

Take the mobile phone screen protective film as an example. Since the mobile phone screen protective film is generally made of multi-layer protective film, the stamping and segmentation are prone to defects such as uneven edges and poor consistency of multi-layer films, which greatly affect its screen protection effect. In order to improve the above problems, there is currently a laser cutting method that can well complete the cutting of multi-layer films. However, due to the high power of laser cutting, the edge of the film tends to turn yellow, black, and zoom. The above phenomenon will seriously affect the appearance of the finished film, and of course it will also destroy the use effect of the film.

In addition, the current laser cutting method generally clamps the film on the fixture, and then cuts by adjusting the path of the laser focus on the film. In this process, whether the accurate positioning of the film will have a decisive impact on the quality of the cut product. Traditional laser cutting usually relies on the fixture to match the positioning points on the film to achieve positioning. The positioning accuracy of this fixture is limited, and the relative edge error of the positioning points printed on the film is large. Therefore, the positioning methods currently used have the disadvantages of insufficient accuracy and large errors. In summary, all film cutting methods have many defects.

The Thin film laser cutting equipment developed by Laisai Laser overcomes the shortcomings of existing thin film cutting technology, has high cutting efficiency, greatly improves the output of finished products, and reduces staffing. It has a simple structure, accurate positioning, and convenient adjustment to meet the requirements of automation. It adopts a high dynamic rigidity system to meet the requirements of high-speed, high-precision, and high-efficiency laser cutting. Precision laser cutting has no vibration deviation, stable mold cutting spacing, and excellent performance. It can meet the functions of appearance cutting, size cutting, full cutting, half cutting, etc. for various thin film products.

It is mainly used for high-precision cutting of non-metallic film materials such as GDF film, polarizer, touch screen PET, OCA, electronic paper, mobile phone explosion-proof film, flexible oled, etc.
