Flow Control and Gate Design

amc.gif (6172 bytes)
  • Control of the metal flow in the die is a key factor in producing sound die castings.

    • Metal must flow rapidly and uniformly into the die, minimizing turbulence and entrapped air.

  • A key feature in die design is the positioning of the runners and gates -- the passages that feed molten metal into the die cavity.

Well-designed gates are positioned to permit rapid flow into the die cavity, minimizing turbulence and long flow paths for the molten metal.
