PURPOSE: A moldable metal manufacturing method with excellent injection-moldability is provided to mold metal to various shapes at a room temperature without specific molding conditions and to manufacture the metal capable of freely changing properties according to the purpose of use. CONSTITUTION: A moldable metal manufacturing method with excellent injection-moldability is as follows. Aluminum, copper, beryllium, and nickel are successively injected. After the aluminum is completely melted, the copper is inputted and melted at a melting point of the copper. After the copper is completely melted, the beryllium is inputted at a melting point of the beryllium. After the beryllium is completely melted, the nickel is inputted at a melting point of the nickel. [Reference numerals] (AA) Step of selecting materials to use→Purity is important(99% to 99.999%); (BB) Step of uniformly distributing according to weight→Input amount is important(Error range±0.1% to 0.3%); (CC) Step of inputting copper at the melting point of copper after previously inputted aluminum is completely melted(Inputting according to time and temperature/determined by an expert); (DD) Step of inputting beryllium at the melting point of beryllium after the inputted copper is completely melted(Definitely important so that the production of materials is stopped if failed to check temperature and time); (EE) Step of inputting nickel at the melting point of nickel after the beryllium is completely melted(Temperature is especially important); (FF) Step of casting before reaching the boiling point of aluminum after the nickel is completely melted(In order to avoid a failure, tapping timing after completion should be checked with a naked eye and a mechanical device should be adopted to facilitate timing control); |
