Filed: 2003-01-21
Abstract: <P>PROBLEM TO BE SOLVED: To enhance the analysis precision of the flow of a molten resin in a mold designed newly by removing the trouble caused by the difference between a simulation result obtained by a flow analysis system for the molten resin and a molding result obtained by actual molding using a molding apparatus.  <P>SOLUTION: The simulation result obtained by setting an experimental conditions to the flow analysis system using a testing mold model almost uniform in the cross sectional shape of a resin flow channel is compared with the molding result obtained by letting the molten resin actually flow under the same conditions as the experimental conditions using a testing mold almost same to the testing mold model. The difference of the flow easiness of the molten resin between both results is calculated as the difference of the flow distance of the molten resin in the resin flow channel.
