Disclosed is a manufacturing method of a skin for an interior material of a vehicle. The manufacturing method of a skin for an interior material of a vehicle comprises: a fixing step of tightly attaching a front surface of the skin to a top surface of a table; and a cutting step of cutting a part of the rear surface of the skin with a knife to form a rupture groove, wherein the skin is attached to a front surface of the interior material of a vehicle, a concave groove is formed on the interior material to be ruptured by expanding pressure of an air bag, and a rupture groove to be ruptured by expanding pressure of the air bag is formed in front of the concave groove on a rear surface of the skin. According to the present invention, there is no need for additionally installing a machine such as anti-seismic facility, an actuator and the like in a production line and thermal deformation does not occur in a manufacturing process. Accordingly, a target portion is accurately ruptured by the expanding pressure of the air bag.
자동차 내장재용 스킨 제조방법이 개시된다. 본 발명의 자동차 내장재용 스킨 제조방법은, 자동차의 내장재 전면에 부착되는 스킨(skin)으로서, 내장재에는 에어백의 팽창압력에 의해 파열되는 오목홈이 형성되고, 스킨의 후면에 에어백의 팽창압력에 의해 파열되는 파열홈이 오목홈의 전방에 형성되며, 스킨의 전면을 테이블 상면에 밀착시키는 고정단계; 및 스킨의 후면에 나이프로 칼집을 내 파열홈을 형성하는 절개단계를 포함하는 것을 특징으로 한다. 본 발명에 의하면, 생산라인에 방진시설이나 액추에이터 등 기계장치를 추가 설치할 필요가 없고, 제조과정에서 열변형이 발생하지 않으며, 에어백의 팽창압에 의해 목표 부위가 정확하게 파열되도록 이루어지는 자동차 내장재용 스킨 제조방법을 제공할 수 있게 된다.
