On a weekly to monthly basis, Molding and Casting Workers measure and cut products to specified dimensions, using measuring and cutting instruments. They might also patch broken edges or fractures, using clay or plaster.

In addition, they place forms around models and separately immerse each half portion of a model in plaster, wax, or other mold-making materials.
