The production of metal tool boxes with drawers involves several key manufacturing processes. Factories typically start with sheet metal, which is cut to size using CNC machines for precision. This ensures that each component will fit perfectly, especially the drawers, which must slide smoothly and be easy to access. After cutting, the metal is stamped or bent into shape and assembled into a frame that forms the backbone of the tool box.
