摘要： PROBLEM TO BE SOLVED: To provide a plastication method for a fiber-reinforced thermoplastic resin which can stabilize a plastication time while controlling the breakage of fibers contributing to the mechanical properties of an obtained molding in a plastication process, and to provide a molding method for molding the resin effectively.
SOLUTION: In the plastication method for the fiber-reinforced thermoplastic resin, an injection molding machine has a barrel the temperature of which can be controlled individually in a plurality of zones, a hopper installed above one end on the upstream side of the barrel, and a screw which is installed in the barrel and has a compression ratio below 2. Pellets are supplied into the barrel through the hopper and melt-kneaded. The resin is plasticated under improved plastication conditions in which the feed of the resin in the barrel is controlled so that the plastication time of the first shot is 1.1-3 times as long as the plastication time of the first shot when the resin is plasticated under ordinary conditions. In the molding method, the resin is molded after being plasticated by the method.

摘要： PROBLEM TO BE SOLVED: To provide a method for determining the production parameter of an injection-molded product, capable of achieving the miniaturization of an injection molding machine and the reduction of a production cost by suppressing the maximum mold clamping force low even when a resin product having an arbitrary shape is injection-molded.
SOLUTION: When injection molding is performed using a mold having a plurality of resin inflow channels R communicating with a cavity CV, a production parameter, which is used for setting the inflow rate of a resin material into the cavity from the resin inflow channels in a time series manner in order to control the maximum clamping force occurring during an injection molding process, is calculated beforehand by a combination of a numerical value analyzing technique for calculating the injection molding process and an optimization technique due to the support of a computer.
