Using castings to make castings
Foundry Management and Technology
Every casting made in a sand mold requires a pattern, and each design of a cast part must have its own unique pattern equipment. Patterns, the highly specialized full-size models of the finished part establish the final shape of the mold cavity and the casting itself. Patterns are required to be always compatible with foundry methods, materials, and machinery. Over the years, patternmakers has not been static, rather, concept methods, solution of problems, and materials have changed with the times to keep pace with rapidly advancing technologies. At present, patternmakers are considering the advantages of creating tooling from a casting as a way to preserve patterns.
