Abstract
An injection molding apparatus includes a melt furnace and a metal supply system located in the melt furnace. The metal supply system includes a pump. The injection molding apparatus also includes a first metal inlet from the melt furnace to the metal supply system and a vertical injection mechanism adapted to inject liquid metal into a die system. The injection molding apparatus also includes a second metal inlet from the metal supply system to the vertical injection mechanism.
Claims16
An injection molding method, comprising:
- providing solid metal into a melt furnace;
- melting the solid metal into a liquid state in the melt furnace;
- providing the liquid metal from the melt furnace through a first metal inlet into a metal supply system located in the melt furnace;
- pumping the liquid metal from the metal supply system through a second metal inlet into a vertical injection mechanism;
- lifting the vertical injection mechanism and the metal supply system together towards a mold prior to a step of injecting;
- and
- injecting the liquid metal from the vertical injection mechanism into the mold located above the vertical injection mechanism.
