Hardware mold (or cold work mold) is a process of processing materials (metal or non-metal) in different ways at room temperature, such as punching, bending, stretching, forming, powder pressing, etc., in order to obtain the desired parts or semi-finished products. During production, molds often encounter various problems such as wear, chipping, cracking, etc., which can affect production and even require downtime for maintenance. So, mold makers and producers hope to solve related problems through different methods.
