When injection molding is done decisive manner of production parameter of the injection molding item and production manner of the injection molding item

摘要

PPROBLEM 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. PSOLUTION: 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.
