Hot-runner is getting more popular in injection molding process especially for the high surface-quality product. This work is to develop a navigating system for the hot-runner design with knowledge management. This web-based system provides step-by-step functions to guide the user through the sub-processes of product specification, manifold design, component assembly, spacer design and cylinder plate. Moreover, the knowledge database provides easy access of standard components which can be assembled automatically or semi-automatically. The system can provide the proven 3D hot-runner design with much shorter time.
