Beschreibung
Zusammenfassung:	The present invention relates to a method manufacturing of a frame structure for a portable device and, more specifically, to a manufacturing method of a frame structure for a portable device capable of shortening a processing time and increasing the rigidity of a material. The method comprises: a rolling step of passing a metal material through rollers to form a frame member; and a die casting step of inserting the frame member into a die casting mold and injecting a molten metal into the die casting mold to form a metal embedded bracket integrally with the frame member. 본 발명은 휴대단말기용 프레임 구조물 제조방법에 관한 것으로서, 보다 상세하게는 가공시간을 단축시킬 수 있고 소재의 강성을 높일 수 있는 휴대단말기용 프레임 구조물 제조방법에 관한 것이다. 본 발명의 휴대단말기용 프레임 구조물 제조방법은, 금속 소재를 롤러 사이로 통과시켜 프레임 부재를 성형하는 롤링단계 및 상기 프레임 부재를 다이캐스팅 금형에 삽입한 후 상기 다이캐스팅 금형에 금속 용탕을 주입하여 금속 내장 브라켓을 상기 프레임 부재와 일체로 형성하는 다이캐스팅단계를 포함하여 이루어지는 것을 특징으로 한다.
