Injection molding (IM) has been the most widely used manufacturing process for making plastic products mainly due to its high efficiency and manufacturability. The design of injection molding systems relies heavily on material data and related information. The availability of right material information at right time is of utmost importance for the design, operation and maintenance of the injection molding process. In this paper, a concise, and conceptual Injection Molding Material Information Model (IM-MIM) is proposed to support necessary computer-based modeling, calculation and management of material data. In this paper, we study different steps of the IM process from the information-modeling viewpoint to identify the role and influence of material properties and behaviors in decision-making process. We further developed a four-level IM-MIM model framework, which provides a foundation for different material-related activities or analyses. Several key components in the IM-MIM, which consists of the material data, physical and behavioral properties, thermodynamic and transport properties, and other material information like rheological and mechanical properties, are presented in detail.

This study presents a Solidworks� Plastics application in a company in the Automotive Industry for the aftermarket of auto parts manufactured by the injection molding process, the focus is on the redesign of an injection vein plate for achieve uniform filling of a 16 cavity mold with a geometry made up of a mixture of natural rubber and two metal components. This work proves that the use of symmetrical commands is not always the best option. The distances between runners were not taken into account as a source of the future wears problems in the mold. A layout is created with a combination of 2D and 3D sketches by turning the injection chanels 180� in the problem cavities to increase the distances between runners and the filling of the 16 cavities is verified by simulation. It is also demonstrated by simulation that increasing the injection point size is not necessarily always the best option for cavity filling.
