Metal Casting Process - thelibraryofmanufacturing.com

Structural supports that hold the core in place are called chaplets. The chaplets are made of a material with a higher melting temperature than the casting's material, and become assimilated into the part when it hardens. Note that when manufacturing a metal casting with a permanent mold process, the core will be a part of the mold itself.
