According to the present invention, prepared are a first sheet material made of a material resisting an impact and a second sheet material made of a material which absorbs an impact and is different from the first sheet material. Moreover, after a portion where the first and second sheet materials come in contact with each other is welded, the welded first and second sheet materials are cut by a first and a second blank respectively forming the upper portion and the lower portion of a center pillar. After the welded first and second blanks are heated, the first and second blanks are supplied to a mold to be molded into the center pillar, and the molded center pillar is rapidly cooled inside the mold.

    본 발명에 따른 센터필러 제조방법은, 먼저 충격에 저항하는 소재로 이루어진 제1 판재와, 제1 판재와 종류가 상이하게 충격을 흡수하는 소재로 이루어진 제2 판재를 마련한다. 이어서, 제1,2 판재를 맞대어 맞댄 부위를 용접한 후, 용접된 제1,2 판재를 센터필러의 상부와 하부를 각각 구성하는 제1,2 블랭크로 재단한다. 이어서, 용접된 제1,2 블랭크를 가열한 후 금형에 공급해서 센터필러로 성형하며 성형된 센터필러를 금형 내에서 급냉시킨다.
