Abstract
Production process of plastic products depends significantly on cost of quality, time to market and cost to produce appropriate molds. Basic course of improvement and rationalization of production process for plastic injection molds is directed on automation design mold and their process planning. Working area of process planning in large number of cases is the bottleneck in production systems, because of impossibility of development multipurpose program system which would be effective in planning and designing a huge number of activities that makes process planning. The model and program system for automated process planning for plastic injection molds manufacturing have been developed, in order to solve this problem. This solution presents integrated CAPP system, which is based on integration of CAD, CAPP and CAM activities. Keywords: Plastic injection mold manufacturing, CAPP, Data base, Knowledge base
