Abstract
A system for die casting including a die having a die cavity. There is also a vacuum chamber and a device for creating a vacuum in the vacuum chamber. The die casting system further includes an injection device for introducing a fluidically based material, such as molten metal, into the die cavity from the vacuum chamber. The injection device is in fluidic communication with the die cavity and is at least partially disposed within the vacuum chamber. The die casting system also includes a device for providing the fluidically based material into the injection device. The providing device is separated from the injection device and is preferably disposed within the vacuum chamber. A method of die casting includes the step of providing, such as by pouring, fluidically based material into an injection device within the vacuum chamber. Then, there is the step of forcing the fluidically based material into the die cavity with the injection device.
