Abstract: The present invention obtains a high degree of hardness on a heat treatment portion by forming a dense martensite structure through high energy density of laser and rapid cooling, improves reliability by controlling the temperature on the heat treatment portion, minimizes damage and deformation on a base material, and reduces heat treatment costs which may not require separate maintenance costs. Requirements are satisfied by irradiating a portion to be heat treated on the base material with laser for 0.5 to 5 seconds, wherein the requirements include heat treated depths of 3 to 5 mm, heated widths of 1.5 to 6 mm, and heat treated hardness of 650 mHv or more with respect to fine non-through holes, through holes, stepped non-through hole or stepped through hole having diameters of 10 mm or less and depths of 5mm or less formed on the base material. The laser has the output of 600 to 900W and is emitted on a portion on the upper side of the base material to be heat treated at the angle of 70 to 105°, and then the laser irradiated portion is naturally cooled to complete heat treatment.

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.
