One of metalcasting’s strongest selling points is its ability to encompass several parts, often in the form of a welded assembly, into one component. This is possible because the nature of the metalcasting process lends itself to complex geometries. At the heart of many of these complex geometries is a core or core assembly. A core is a shaped body, usually made of sand, which forms the interior part of the casting, like the cavity the pit makes in the fl esh of a peach. In metalcasting, the mold provides a space for the molten metal to go, while the core keeps the metal from fi lling the entire space. Cores allow you to incorporate
holes in your design, but these holes don’t have to be limited to the see- through kind you’d fi nd in a length of pipe. Cores can take on a variety of angles and shapes, and more than one can be used per casting. Sometimes, an assembly of cores is constructed to create a web of internal passageways and chambers. For many seemingly impossible parts, imagination and cores can turn a fl oundering design into a winning engineered component. Read the whole article at
