The faceplate is mounted in the recess and includes on outside plate and an inside faceplate. The outside plate has a thickness that is 1.0 to 2.0 millimeters and is made of high strength material. The inside plate has a thickness that is 0.5 to 1.8 millimeters and is made of high strength material. The inside plate, which is hollow or meshed, is connected to the outside plate. Therefore, the COR of the faceplate will be more consistent, and the faceplate can be fabricated with a large area.
