The use of human-machine interface display operation, industrial computer control, high-tech content. According to the list of engineering materials one-time optimization of the material, no need for manual secondary feeding, professional material loss optimization system, to ensure zero material loss. The feeder uses a fully closed-loop CNC system to ensure higher accuracy. The work station uses a 10-degree adjustable mold, suitable for a variety of different pressure bars. Sawing uses stepper motor screw in- and more stable speed. At the same time can cut 6 pressure strips, more efficient. Suitable for large and medium-sized door and window processing enterprises continuous production
