Document Type and Number:
WIPO Patent Application WO/2023/058780
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a product having a complex internal shape, the method including: a component manufacturing step for manufacturing a pair of components by injecting molten metal prepared using an aluminum alloy into a die casting mold; and a component joining step for brazing the pair of components into a brazed joint. In this manufacturing method, a simple step, in which a die casting method that uses reactive gas is used to manufacture a new aluminum alloy having a high eutectic point into components in which no bubbling occurs, after which the components are brazed into a brazed joint, makes it possible to obtain the effect of being able to quickly and accurately mass-produce a product having a complex internal shape.
