Abstract
Provided is a high-pressure casting method and a high-pressure casting device which are capable of safe and high-quality casting of a high-fusion-point metal having a fusion point exceeding 1000 K. After melting a casting material () inside a melting container () of cartridge type, the melting container () is linearly moved to pass through a guide () attached to a casting port bush () to thereby be communicated with the casting port bush (). The melting container () is brought into close contact with the guide () and is setting to a cooling state. After the elapse of prescribed time, a plunger () is brought into contact with a plunger tip (), and is immediately transferred together with a molten metal to the casting port bush (). The molten metal is pressurized inside the casting port bush (), and is injection-filled into a cavity ().
