PET, as a performance-balanced industrial-grade plastic, possesses many significant advantages. Its high transparency and compliance with food-contact safety requirements make it one of the most popular materials in the packaging industry; in addition, due to its good electrical insulation properties and ease of cleaning, PET is also widely used in the electronics and medical industries. In PET processing, laser processing, with its flexibility, high efficiency, and high precision, has become a very well-established production and processing system for PET.
In laser cutting of PET, the laser control system plays a decisive role in cutting quality, yield rate, efficiency, and precision. Because PET has a relatively low melting point and is thermally sensitive, the laser control system is often more critical than the laser source itself during processing. In order to avoid issues such as melted edges, deformation, and stringing, precise control of the energy density per unit length is required when cutting PET, which is highly dependent on the capability of the laser control system itself. The laser control system’s ability to coordinate speed and power directly affects the cutting quality at corners. A high-performance laser controller also has strong micro-graphic processing capability, which can effectively prevent edge stringing or contour distortion.
Laser control controller with different performance levels determine whether PET cutting edges turn yellow, whether the finished parts are consistent, and whether the edges are clean. If there are problems with your PET cutting products, remember to check the laser controller first.
