Learning Objective

Understand the anatomy of a casting mold by exploring it interactively. By the end of this lab you should be able to:

  • Identify all eleven parts of a two-part sand casting mold.
  • Trace how molten metal flows from the pouring basin to the casting cavity.
  • Understand how the cope and drag form the cavity along the parting line.
  • See how the core, core print and riser control internal shape and shrinkage.
