[0002] Die cutting is a common processing method. It uses molds or cutters to cut and process materials such as plates, paper, and plastics. During the die-cutting process, the mold will apply pressure to cut the material into the desired shape and maintain precise size and shape. Die cutting is widely used in the packaging industry, advertising industry, printing industry, and various other manufacturing fields. When the mold needs to be replaced, the operator's arm needs to reach into the bottom of the hydraulic cylinder to replace the mold, which is very dangerous.
