    The difference between die cast aluminum and pure aluminum

    Casting is a metal smelting process, usually by using the gravity of the metal in the mold for casting. But “aluminum die-casting” is not done by gravity, it’s done by pressure. It’s kind of like injection molding. But it has a higher technical content of the core, cooling and other systems. In general, materials are delivered through a centralized inlet into the cavity to be cast and “molded” to form the part. Aluminum has a history of more than 100 years since it was discovered by the Danish scientist H.C.Orsted in 1825. It has been more than 100 years since…
