Résumé : |
Short product lifecycles and high demands on injection molded parts require efficient product development methods. Besides new process management strategies, simulation is an important component at an early stage of product and mold development. This article validates the simulation of the water-assisted injection molding technique, compares two fluid-assisted injection molding techniques (FAIM) and presents a typical practical application. |
