Abstract

When a powder material () is molded by introducing the material into a cavity () between a lower punch () and a die (), compression molding the material between upper and lower punches (and) into a compact () of desired shape, and moving up the lower punch () to eject the compact (), a lubricant is applied to the interior surface of the die () by fitting a pad () around the lower punch () and impregnating the pad with the lubricant. Since the lubricant is applied on every molding operation, molding operation can be continuously carried out.
