Disclosed is a crash box-integrated bumper beam system for an automobile using injection-molding. It is possible to satisfy low speed collision regulations and 40% offset rigid barrier test (RCAR) at the same time by integrating the bumper beam and the crash box through the injection-molding. Besides, the present invention utilizes the injection-molding which can significantly reduce development investment costs and costs when manufacturing an automobile. The present invention relates to the bumper beam having a tube-type crash box formed on both sides in the longitudinal direction, in which the crash box has a double closed end face column in forward and backward directions and is integrated with the bumper beam through injection-molding.

    사출공법을 이용하여 범퍼빔과 크래쉬박스를 일체형으로 제작하는 것으로 저속충돌 법규사항 및 RCAR(40% OFFSET RIGID BARRIER TEST)를 동시에 만족할 수 있으며, 차량 제작시 개발투자비 및 원가를 대폭 저감할 수 있는 사출공법을 이용한 차량용 크래쉬박스 일체형 범퍼 빔 시스템이 개시된다. 본 발명은 양측에 전후방향으로 형성된 튜브형의 크래쉬 박스를 구비하는 범퍼 빔에 있어서; 상기 크래쉬 박스는 전후방향으로 2중의 폐단면 기둥을 가지며, 범퍼빔과 일체형으로 사출 성형된 것을 특징으로 하는 차량용 크래쉬 박스 일체형 범퍼 빔 시스템을 제공한다.
