Abstract: The features of Advanced Manufacturing Technologies (AMT) are analysed, a key technology of AMT is information integration and union product model is the base of information integration are pointed out. So the STEP based Injection Mold Product Model which consists of a general information model, a main feature information model, a structural information model and a auxiliary information model is presented. It uses he level structures recommended by STEP and can include the activities. Of life cycle. The submodel realizes information share by use and reference. So the SIMPM - based system can completely integrate.

Key words: Advanced manufacturing technology, Information integration, Product model, Standard for the exchange of data
