This study presents a knowledge-based engineering system for the design of injection molded plastic parts which is built around a commercial object-oriented design language. Knowledge-based engineering is an implementation paradigm in which the knowledge about the part is stored along with its geometry and the knowledge is used to verify the manufacturability and processability of the part. This system enables the designer to represent the plastic part in terms of hybrid features which associate product and process knowledge with part geometry. Engineering rules about part moldability and strength, process and material considerations, and mold design are captured in the system. To illustrate the capability and tqjplication of the system to real-world problems, the design of an enclosure for a portable data entry device is pursued. This exercise demonstrates the effectiveness and robustness of the system which applied appropriate rules at different stages of design to make the part inherently moldable.
