In a computer-aided resin behavior analyzer that analyze behavior of a continuous fiber and long discontinuous fiber incorporated in a resin during molding in a mold under predetermined molding conditions through a simulation program installed on a computer, the simulation program is configured to calculate, when analysis conditions including at least multiple nodes F of the fiber is inputted, a bending rate Af of the fiber with respect to an evaluated length obtained from at least one node Fn among multiple nodes F anticipated under the molding conditions based on the analysis conditions, and to evaluate bending of the fiber based on the bending rate Af with respect to the evaluated length.

A first sealing member and a second sealing member are disposed respectively on a lower mold and an upper mold. During a process of closing the lower mold and the upper mold, a gap between the molds is sealed by the first sealing member, thereby forming an enclosed space between the molds. Thereafter, a gas in the enclosed space is discharged. As the closing process progresses, the enclosed space is divided by the second sealing member into a sealed room and a production cavity, followed by a liquid resin being supplied to the production cavity.

An FBG (Fiber Bragg Grating) sensor is equipped with a plurality of stress detection sensors made up from optical fibers in which gratings that reflect light of a specified wavelength are arrayed, and a stress direction converter that converts stresses applied from the exterior into stresses of a direction in which the gratings are arrayed, and which transmits the stresses to each of the gratings. Consequently, the stress direction converter can transmit stresses, which are applied from a body, to a plurality of gratings.

An injection rate (cm/sec) of a screw feeder at the time of starting an injection is the largest and the injection rate (cm/sec) thereof gradually or sequentially decreases until an end of injection so that a temperature of a melted resin reaching the end portion of a cavity decreases within a range where the melted resin is not solidified.
