Chapter 12: Pattern Equipment
Pattern equipment is the tooling utilized to form the mold cavity of a casting. This chapter first discusses the following factors that should be considered for determining the type of pattern equipment: number of castings to be produced, mold processes to be employed, dimensional tolerances required, casting design, and pattern cost. It also discusses the factors that should be considered when engineering a pattern. The chapter then presents the types of materials used for pattern construction. It provides an overview of patternmaker's shrinkage allowance. Finally, the chapter presents the factors that govern the space requirements for pattern storage.
