Molding is the manufacturing process by shaping liquid using a rigid frame called a mold.  The mold is a hollowed-out block that is filled with a: 

  • Liquid
  • Plastic
  • Glass
  • Metal
  • Ceramic Raw Material

The liquid hardens in this mold and the final shape is formed.  A mold is the counterpart to a cast.  A release agent is typically used for removal of the hardened substance from the mold easily.
