New solution from 4JET to quickly produce inner contours with the laser

Until now, the laser-based separation process used in PEARL systems was only suitable for processing glass along its subsequent outer contour. The reason for this is the "zero-gap cut" generated by this process, which does not allow the cut component to be detached in its entirety without cutting open the edge material at certain positions.

Further development now makes it possible to cut inner contours and to dissolve out the inner core. Filamentation of the glass is achieved at the well-known high cutting speed of up to more than 1 m/s. A downstream process allows the components to be dissolved out without any loss of quality. The process is highly productive – for example, the side sliding window for a small van can be dissolved out in less than 20 seconds. The separation process leading to success must be adapted once to the respective contour and the specific glass properties.

The new laser-based cutting process for interior contours is thus an ecological and cost-efficient alternative to conventional processes such as waterjet cutting
