Die and mold industries make up the base of Japanese key industries such as automobile and electric appliance. In the turbulent era when price slashing, globalization, and information revolution are progressing at increasingly faster rates, "production cost cutting" and "shorter delivery times" are top priority. To reduce the delivery times in die and mold production process, three points are to be considered: shortening design hours, simplifying process and shortening each process times. Referring to the trend of up-date die making technologies, new tool steels are introduced. Pre-hardened steels, free machining steels and easy to repair weld steels are contributing to the process time saving. Technical software on application technology also works for shorter delivery times. Software covering from die material selection to process simulation will be widely and practically used in the future. New tool steels and application technologies for precise die and molds are also mentioned in this article.
