1. a diel, for punching press is carried out to punch process with material, is characterized in that,The part contacting with material with punching press when it carries out punch process, is formed with the plated film forming by physical vaporous deposition,Described plated film is by the TiN layer that is formed directly into mold base material surface;

  • Be formed on the Ti (C on described TiN layer surface xn y) layer, wherein, x+y=1, x <

    1, along with surperficial away from described TiN layer, the value of x increases to approach 1 gradually;

    Be formed on described Ti (C xn y) the surperficial TiC layer formation of layer, The thickness of described plated film is below 4 μ

    m,The surperficial surface roughness Ra that described mold base material forms plated film is below 0.1 μ

    m,The case hardness that is formed with the described diel of described plated film is counted 3000~

    4000HV with Vickers hardness.
