    • Disclosed is a method for manufacturing a bumper crash box for a vehicle by using a laser heat treatment which is capable of improving performance when testing a high speed collision or a research council for automobile repairs (RCAR) by selectively increasing strength in a necessary part by locally performing a heat treatment. According to an embodiment of the present invention, a method for manufacturing a bumper crash box for a vehicle by using a laser heat treatment comprises: (a) a step for preparing a bumper crash box main body formed from a steel plate; and (b) a step for forming a strength reinforcing part by locally performing a laser surface heat treatment to the bumper crash box main body. In the (b) step, the strength reinforcing part is formed in a place of 2 or more of the bumper crash box main body. Since the speed of a laser surface heat treatment is increased to a rear end from a front end combined to a bumper, strength in the rear end is relatively increased in comparison with the front end.

    • PURPOSE: A sub frame manufacturing method is provided to reinforce the intensity of a structurally weak part by locally performing the structurally weak part of a sub frame with induction heating without putting a reinforcing member by welding. CONSTITUTION: A sub frame manufacturing method comprises a press molding step(S110), a welding step(S120), an induction heating process step(S130), and a cooling step(S140). The press molding step molds hardened steel with a press and comprises a front, a rear, a right, and a left member. The welding step forms a sub frame main body by welding the first and the rear member and the right and the left member. The induction heating process step selectively performs an induction heating process on the surfaces of the right and the left member including structurally weak intensity. The cooling step cools the heat processed sub frame main body. [Reference numerals] (AA) Start; (BB) End; (S110) Press molding; (S120) Welding; (S130) Induction heating process; (S140) Cooling;
