Summary:The invention discloses a manufacturing method for a copper handicraft. The manufacturing method comprises the following steps that 1, an appropriate amount of copper, zinc and tin are weighed in proportion and put into a crucible to be heated; 2, after the copper, the zinc and the tin in the crucible are melted to form molten copper, the molten copper solution is injected into a mold cavity; 3, after the molten copper in the mold cavity is cooled, a sand shell outside the mold cavity is shocked broken to form a rough blank body; 4, coloring processing is conducted on the surface of the rough blank body to enable the rough blank body to form a prototype; and 5, wax sealing is conducted on the surface of the prototype. Compared with the prior art, the copper handicraft prepared through the manufacturing method is lower in defective rate.
