The chapter presents some of the significant enhancements that have been made in the versions of SolidWorks for Mold Design. Such enhancements have made SolidWorks to be very user-friendly, efficient, and effective in mold design. Mold design is a special area of manufacturing processes that considers the process for creating the lowerand upper-half of the mold that is required for producing forged, cast, and plastic parts. Due to its specialty, there is very limited information that is available for a proven methodology using the automated software approach. Mold analysis tools are utilized by the designers of molded plastic parts and by the designers of the mold tools that are used to manufacture those parts. Mold tools span from initial analysis to creating the tooling split. The result of the tooling split is a multibody part containing separate bodies for the molded part, the core, and the cavity, plus other optional bodies such as side cores.
