摘要： A casting method includes loading molten metal into a cavity from a sleeve, and sending a gas into the cavity from the outside of the cavity, except the sleeve, to pressurize a gas in the cavity and to increase the pressure value of the gas in the cavity to the atmospheric pressure or higher.

摘要： A casting device includes a mold having a cavity, a supply path that is connected to a gate of the cavity and configured to supply a molten metal to the supply path, and a gas flow path that is connected to the supply path and configured to supply a gas to the supply path. In the casting device, a molten metal is atomized by causing the gas supplied from the gas flow path to collide with the molten metal passing through the supply path, and the atomized molten metal is supplied to the cavity.

摘要： A heat exchange device includes: a first flow path through which a first fluid flows; a second flow path through which a second fluid flows, the second flow path being separated from the first flow path by a tubular partition wall and positioned close to an outer circumference of the tubular partition wall; an offset fin installed in a tubular shape extending along an inner circumferential surface of the tubular partition wall; and a pressing member disposed inward of the offset fin such that the offset fin is pressed toward the inner circumferential surface of the partition wall while being elastically deformed. The offset fin is provided with a plurality of wave-shaped portions arranged in an axial direction of the tubular partition wall and positions of wave-shapes of the wave-shaped portions adjacent to each other are offset from each other in a circumferential direction of the tubular partition wall.
