摘要：
A blemish free surface is formed on the cavity side of a set of mold or die blocks, said set consisting of a core side and a cavity side, by use of a softer alloy on the core side as contrasted to the cavity side so that, during plastic injection molding, the core side will wear at the parting line in preference to the cavity side whereby erosion of the set occurs on the core side in preference to the cavity side leaving the cavity side erosion free.
