A method for manufacturing a metal pattern for precision casting of precious metal ornaments using natural materials is provided to reproduce the exterior shape of a natural material by preparing a metal mold in a lost wax process method. A method for manufacturing a metal pattern for precision casting of precious metal ornaments using natural materials includes: a wax tree preparing step of fixing leaves, petals(11), or insects along a pillar of a wax tree; a plaster frame forming step of letting the wax tree be embedded in the plaster frame(24); a wax tree removing step of putting the plaster frame in a high frequency heating furnace to form a casting path and a casting forming space inside the plaster frame; a melting metal injection step of mounting the plaster frame on a case to inject melting metal into the casting forming space; a cooling step; a plaster fusing step; and a metal mold finishing step. |
