    • A mold for plastic forming having excellent seizure resistance controlled by adjusting its surface properties. In addition, a process producing the mold, that includes: roughening a surface of a base material by a shot blast method to adjust its arithmetic averaged roughness Ra: higher than 1 μm but 2 μm or lower; polishing the surface of the base material to adjust its skewness Rsk to 0 or lower while retaining Ra: 0.3 μm or higher; and forming a hard film on the surface of the base material where the surface of the hard film has an arithmetic averaged roughness Ra: 0.3 μm or higher but 2 μm or lower and skewness Rsk: 0 or lower. Adjusting the surface of the mold to have a non-concave-biased configuration, limits the capacity for concaves to accumulate lubricant, such that the lubricant is sufficiently deposited on the surfaces of the convexes.
