The present invention relates to a method of molding an automotive external quarter glass using white protective wrap and, more specifically, to a method of molding an automotive external quarter glass which is provided integrally with a mold portion (120) and a decorative portion (130) made by different materials along an outer line of an external panel (110) and to be mounted on a vehicle body. In particular, the method comprises: a first combining process (S110) for combining a blue first protective wrap of PE material on a surface of a material plate for a decorative portion (130); a press process (S120) for molding a plate having undergone the first combining process (S110) into a shape corresponding to an external line of the external panel (110); a bending process (S130) for bending an outer end of the plate having undergone the press process (S120) to form a stepped portion so as to be accommodated into a mold portion (120), thereby forming the decorative portion (130); a peeling process (S140) for removing the blue (PE) first protective wrap from the decorative portion (130) having undergone the bending process (S130) to inspect the surface thereof; a second combining process (S160) for attaching a white second protective wrap (150) to the surface of the decorative portion (130) having passed the inspection; and an injection process (S170) for introducing the decorative portion (130) having undergone the second combining process (S160), a synthetic resin for the mold portion (120), and the external panel (110) into a mold to integrally inject the same. The method of the present invention may prevent the decorative portion from damage while increasing workability and productivity.

    본 발명은 백색 보호랩을 이용하여 차량용 외장재 쿼터글라스 몰딩 제조방법에 관한 발명으로, 외장패널(110)의 외측변을 따라서 이종 소재의 몰드부(120)와 장식부(130)를 일체로 구비하여 차체에 장착하는 차량용 외장재 쿼터글라스 몰딩 제조방법에 있어서, 장식부(130)용 소재 플레이트의 표면에 블루색상을 가지는 PE재질의 제1보호랩을 합지하는 제1합지공정(S110); 제1합지공정(S110)을 거친 플레이트를 외장패널(110)의 외측변에 상응하는 형상으로 성형하는 프레스공정(S120); 프레스공정(S120)을 거친 플레이트의 외측단을 몰드부(120)에 수용하도록 단턱 형태로 벤딩하여 장식부(130)로 성형하는 벤딩공정(S130); 벤딩공정(S130)을 거친 장식부(130)에서 상기 블루(PE) 제1보호랩을 제거하고 표면을 검사하는 박리공정(S140); 검사를 통과한 장식부(130)의 표면에 백색 제2보호랩(150)을 부착하는 제2합지공정(S160); 및 제2합지공정(S160)을 거친 장식부(130)와 몰드부(120)용 합성수지와 외장패널(110)을 금형에 투입하여 일체로 사출하는 사출공정(S170);을 포함하여 이루어짐에 따라 장식부의 손상을 방지하면서 보다 용이한 작업성 및 생산성을 도출하는 것이 특징이다.
