【正文】 describe plex shapes in 2D drawing. Reason for using 3D CAD model are wide opportunities to exact describe shape of part, easy making of cut views and detail views. More important reason to use 3D CAD model is CAE process simulation of injection molding and mold manufacturing with CAM software. (2) Using 3D CAD model for CAM software has bee integral part of mould manufacturing. (4) CAE process simulation of injection molding is being stepwise integral part of mould manufacturing process. With help of CAE simulation mould designer can test various construction solution of injection mould without need cost a time consuming mould corrections.2 Injection Molding Process SimulationIn this part of contribution is described analysis of molded part injection (top parthosuing) with help Moldflow Plastics Insight . Material proposed for this simulation is Cycoloy C2100HF. For analysis is prepared mould finite element mesh model. Start model dimensions is determined conventional calculation. In next step is performed runner optimization analysis, to reduce volume and weight of runner system. Determining dimension of runner system by nomogramsThis method belongs to conventional way of puting. Input data for determining runner cross section dimensions are cavity layout, material of molded part and volume of molded part. Cavity layout designed upon determines length of runner channels and with known weight are determined cross section dimensions. (1) Fig. 1 shows cavity layo
