Protective film generally refers to a thin film attached to the surface of a product to protect it from contamination, scratches, and other damage. Common application areas include electronic products, medical devices, and the optical field.
Traditional methods of cutting thin films have characteristics such as fast tool wear, long mold production cycles, low flexibility, and inability to cut complex patterns. Thin films usually require high precision, which traditional die-cutting methods often cannot meet. The emergence of laser die-cutting can well meet this requirement. Laser cutting can cut dense small holes and high-precision, complex patterns on thin films. Due to the high precision requirements of thin film processing, this also imposes strict requirements on the laser control system.
When cutting thin films with lasers, it is easy to cause melting and deformation of the film. Therefore, during thin film processing, it is necessary to choose a laser control system with high precision, fine energy control, and faster motion response. If cutting phone protective films, optical films, and the like, these films not only require high precision but also usually need to be aligned to positioning points during processing. Therefore, it is necessary to choose a Precision Positioning Laser Controller that supports visual alignment, automatic positioning, and distortion compensation.
Thin film cutting also requires the laser control system to perform fine power adjustments to avoid film melting and curling. At the same time, a laser control system with strong graphic processing capabilities can effectively prevent over-cutting.
