Claims (1)
- 압출기에 유입된 펠릿이 합성수지 용융된 상태에서 노즐을 통하여 방출되는 용융물 방출공정, 상기 방출된 용융물을 성형하여 냉각시켜주는 냉각 공정과 상기 냉각공정에 의하여 냉각된 성형물을 몰드에서 탈형시키는 탈형공정으로 이루어지는 장식물, 용기 등의 합성수지 성형물의 성형방법에 있어서,상기 방출공정에서 방출되는 용융물이 그 융점보다 50℃ 정도 더 높은 온도로 용융되어 노즐로 부터 몰드의 외부에 직하방으로 낙하되며;상기 방출공정에 이어서, 직하방으로 낙하된 용융물이 합성수지가 몰드의 외부면에 일정 두께로 입혀지도록 몰드를 회전시켜주는 몰드 회전공정이 구비되며;상기 냉각공정이, 상기 몰드 회전공정에 의하여 회전되는 몰드 외부면에 합성수지가 입혀진 상태에서 상온에서 냉각되며;상기 탈형공정이 몰드 외부에서 이루어지는 것을 특징으로 하는 형틀의 외부에서 합성수지 성형물을 성형하는 방법.
