abstract In the paper results of computer simulations of the injection molding process of selected polymer composite were presented. Authors made an attempt at modeling of injection molding of the polymer molded part technologically not correct. After analyzing the results structural errors were improved and the computer simulation was carried out again. At work the package of providing the engineering software CAD/CAM/CAE -I DEAS NX ver. 11 and simulation software Moldflow Plastics Insight ver. 6.1 were used. A molded part was used to the simulation about the shape of the rectangular prism casing of electronic device. Computer simulations ware performed for different conditions of process. The material for which investigations were performed is the polypropylene composite with 20% percentage of chalk. The results of the injection molding simulation were presented in the graphical way. It was found, that it is possible to exclude structural errors in the mold part designing phase on the grounds of injection molding computer simulations results.
