Abstract: PURPOSE: A sintered product exterior densifying device is provided to improve a product quality by obtaining high precision and to reduce the total manufacturing costs. CONSTITUTION: A sintered product exterior densifying device includes a center core (112), an upper punch (113), a lower punch (114), and a densified mold (116), and a densified rim (120). The center core maintains a cylindrical sinter-molded product of a regular circle shape or irregular circle shape on a device base. The upper punch presses the sinter-molded product, thereby making the upper punch move downwardly. The lower punch draws out the sinter-molded product and presses the sinter-molded product once more in the drawing-out process. The densified mold includes an operation hole of an identical shape on the exterior surface of the sinter-molded product. The densified rim densifies the surface of the sinter-molded product.
