Claims3
A casting method comprising:
- loading molten metal into a cavity from a sleeve;
- and
- sending a gas into the cavity from an outside of the cavity, except the sleeve, to pressurize a gas in the cavity and to increase a pressure value of the gas in the cavity to an atmospheric pressure or higher,
- wherein increasing the pressure value of the gas in the cavity to the atmospheric pressure or higher is started from a point in time at which a part of the molten metal passes through a gate after the loading of the molten metal into the cavity from the sleeve is started.
