  • Cost-conscious molding
    . A plaster model (inset) can then be produced as a design proof. Sections of the model can be color coded to indicate where design modifications are needed to accommodate the casting process. Cast ZA-12 parts have a bright, corrosion-resistant finish and need no heat treating. Specially designed
  • Aluminum
    . The molten metal enters the cavity by gravity. Metal cores are used in simple applications. Sand or plaster cores are used for more complex coring requirements. When using sand or plaster cores, the process is called semipermanent mold. Permanent mold casting is suited for high volume, uniform wall
