A Feature-Based Engineering Methodology for Cyclic Modeling and Analysis Processes in Plastic Product Development

Md M. Uddin, Yongsheng Ma, University of Alberta

Abstract. Injection molding is a widely used automated net-shape manufacturing process for producing plastic parts having relatively complex geometries economically. However, designing plastic parts is a complex and tedious job involving many design-analysis-redesign cycles for counting considerations from other downstream product engineering aspects. It is important to check the designed part meets customer requirements, structural strength criteria, moldability, cost effectiveness etc. Organizations have been using various computer based tools to assist designers and analysts in performing different engineering tasks. Since the engineering aspects are inter-related and mutually constraining, information modeling and association in the cyclic processes are essential to maintain product information consistency by updating engineering models systematically. A literature survey carried out in this regard reveals that although many researchers have done considerable works in product information sharing and integration, in-depth research is still required for product performance based cyclic process modeling among CAD design and engineering analyses, capturing engineering intents in the design process, and associating information across software applications.
