Control of the metal flow in the die
cavity is a key factor in producing sound die castings. Metal
must flow rapidly and uniformly into the die, minimizing sharp
direction changes, turbulence, and entrapped air.
| A key feature in die design is the
positioning of the gates -- the passages that feed
molten metal into the die cavity. |
| Well-designed
gates are positioned to permit rapid flow into the thick sections of the die cavity
and to provide smooth flow paths which minimize turbulence in
the molten metal. |
