Abstract

본 발명은 1차 블로우 성혐품을 2차 블로우 성형하여 최종용기에 성형하기전에, 1차 블로우 성형품을 가열로내에서 열수축시키는 공정을 갖는 내열성 용기의 성형방법 및 그 장치에 관한 것으로, 가열로내에는 1차 블로우 성형품의 종방향에 유속 성분을 갖고, 또 1차 블로우 성형품의 결정화를 촉진시키는 온도의 열풍이 도입되고, 이 열품을 1차 블로우 성형품의 몸통부의 전체둘레 접촉시키면서, 1차 블로우 성형품의 종 방향에 따라 송풍하는 것으로, 1차 블로우 성형품의 몸통부를 그 둘레 방향에 균일하게 가열하여 열수축시키고, 열풍은 1차 블로우 성형품의 몸통부에 대해 종방향으로 속도를 주어 흐르면서 접촉하기 때문에, 열풍온도를 과도하게 높이지 않아도 1차 블로우 성형품의 경막 전열계수가 올라가고, 1차 블로우 성형품의 온도상승이 촉진되는 것을 특징으로 한다.
