Chaplet

 

a metal support for setting up foundry cores in molds and for holding them while the molds are filled with molten metal. The chaplet stays in the body of the casting and must unite well with it. Therefore, it is made of metal similar to the casting: of soft steel for cast iron and steel castings, of aluminum in the case of aluminum castings, and so on. Steel chaplets are tinned or copper coated, for protection against corrosion and for better weldability to the casting. The shape and size of a chaplet depend on the complexity of the casting.
