2. Dimensional Tolerances Precision is paramount in stamping design. Engineers must define appropriate tolerances that account for variations in the stamping process. Tight tolerances may be necessary for components that fit into other assemblies, while more lenient tolerances may be acceptable for less critical parts.

In the context of sand casting, a core is a solid mass of material inserted into the mold to create internal cavities or geometric features that would be difficult to form with the mold alone. Cores can be made from various materials, with sand being the most common, although other materials like metal or ceramic are also used depending on the specific requirements of the casting. The use of cores allows for the production of complex internal geometries, such as passages, holes, or mixed elements, that enhance the functionality of the final cast product.
