After the processing is completed, the customer can choose to take the processed door panel from the feeding area (front outlet) or take the processed door panel from the rear outlet area (rear outlet) as needed. The next door panel can be engraved immediately, which not only saves the time for flipping the door panel, but also saves the time for processing the back side after the door panel is flipped. This saves engraving time and greatly improves the efficiency of engraving. In addition, the upper and lower door panels are processed at the same time, and the processing pattern and position accuracy are much higher than the existing technology.
