Method of simulating resin behaviour in press molding

摘要

In a method of simulating flow behavior of a resin in a process for press-molding the resin by use of a press-molding machine comprising a press apparatus equipped with a hydraulic circuit, and first and second molds at least one of which is connected to the press apparatus, disclosed is a method comprising a step of determining, from a characteristic of the hydraulic circuit, an elastic coefficient of the press apparatus, and an apparent elastic coefficient of the resin, a true compression rate imparted to the resin by the press apparatus, and a step of sequentially analyzing, based on the true compression rate, flow behavior of the resin.
