Abstract

본 발명은 수지심재의 표면 일부 혹은 표면 전체에 표피재를 적층하여 이루어진 적충 성형체의 성형방법에 있어서, 전개율이 높은 부위에 있어서의 표피재의 성형 정도를 높임과 동시에 해당 부위에 있어서의 쿠션성의 저하나 표면 불량을 방지한 적층성형체의 성형방법을 제공하는 것을 목적으로 한다.
표피재의 진공 금형에 의한 진공 성형시, 전개율이 높은 부위에 대해 최종 전개율보다 작게 설정한 러프성형부를 형성하고, 몰드 프레스 상형에 장착할 때, 고전개율이 상형면에 공간부를 개재시켜 러프성형부 혹은 비성형부(단말)를 장착하고, 몰드 프레스 성형시 반용융수지의 수지압에 의해 표피재를 최종 제품 형상으로 형성함으로써 전개율이 높은 부위에 있어서의 표피재의 성형정도를 높임과 동시에 표피재에 있어서의 발포층의 손상을 적게 한다.
