Working size refers to the part of the part directly used to form plastic parts, mainly including the radial size of the cavity and the core. (Including the length and width of rectangular and special-shaped core), the size of cavity depth and core height, the size of center distance, etc. <br>Because the molding shrinkage rate of Polypropylene (PP) is 1% -2.5%, the average shrinkage rate is K = 1.75% <br>. The dimensional tolerance of plastic parts IT = 5
