MOLDING METHOD OF WORKPIECE USING MONOLITHIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To develop a technique to achieve a construction in a short time by keeping the strength and life of a workpiece having conventionally severe variations in the prior art. SOLUTION: Upon injecting a monolithie material into a mold, a plurality of vibrators are mounted in the direction of an internal periphery of the mold and in the height wise direction of the same at a predetermined interval, and as the height of the workpiece in the mold becomes higher upon the same injection, the injection of the monolithic material is continued while starting the drive of the vibrator in succession and in the course of the injection an output thereof is increased.
