Molding flasks and other supplementary equipment are essential for molding complex shapes at competitive production rates and costs. This chapter addresses the design aspects of molding flasks and accessories, the features and handling accessories of molding machines, core making machines and innovations for productivity and quality, and automated core-setting aids.

Most iron and steel castings are produced by casting into sand molds. Sand cores are needed primarily to form hollow cavities in castings for collapsibility and ease of cleaning. This chapter begins with an overview of the classification of molding and core-making systems. This is followed by a section discussing the process involved in shell molding, along with its applications. A brief description of the special casting processes is then presented. Next, the chapter discusses the processes involved in core making. Further, it provides an overview of casting manufacturing. Finally, the chapter provides information on the factors that influence a casting facility layout.
