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

Thin film products usually need to be segmented after production to obtain the required follow-up products. In traditional processing and production, mechanical stamping is used for the cutting of semi-finished film products. There are many problems with mechanical stamping and cutting, such as the easy loss of stamping concave and convex molds, inconvenient stamping and cutting products, easy occurrence of burrs or tears in cutting, resulting in low production efficiency and low product output, requiring a large amount of labor.

Why do thin films use laser cutting technology

Taking Screen protector of mobile phone as an example, as Screen protector of mobile phone is generally made of multi-layer protection film, stamping and segmentation are prone to defects such as uneven edges and poor consistency of multi-layer film, which greatly affect its screen protection effect. In order to improve the above issues, there are currently laser cutting methods that can effectively cut multi-layer thin films. However, due to the high laser cutting power, the edges of the thin film are prone to yellowing, blackening, and zooming. The above phenomenon will seriously affect the appearance effect of the finished film, and of course, it will also damage the use effect of the film.

In addition, the current laser cutting method generally involves clamping the film onto a fixture and then cutting by adjusting the path of the laser focus on the film. During 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 matching fixtures with positioning points on the thin film to achieve positioning. This type of fixture has limited positioning accuracy, and the relative edge error of the positioning points printed on the film is relatively large. Therefore, the current positioning methods have the drawbacks of insufficient accuracy and large errors. In summary, all thin film cutting methods have many defects.

The thin film laser cutting equipment developed by Laise Laser overcomes the shortcomings of existing thin film cutting technology, has high cutting efficiency, greatly improves finished product production, and reduces personnel allocation. Simple structure, accurate positioning, convenient adjustment, and meeting automation requirements. Adopting a high dynamic rigidity system, it meets the requirements of high-speed, high-precision, and efficient laser cutting. Precision laser cutting has no vibration deviation, stable mold cutting spacing, and excellent performance. It can meet the functions of various film products such as appearance cutting, size cutting, full cutting, and half cutting.

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.
