Abstract A preform is produced more efficiently and at lower cost from resin flakes obtained by crushing recovered polyester resin molded articles into flakes. Resin flakes obtained by crushing recovered polyester resin molded articles into flakes are prepared, and the resin flakes are plasticized after heat treatment under reduced pressure. While removing foreign matter from the molten resin obtained by plasticizing the resin flakes, the molten resin is supplied to an injection molding device, and a preform is injection molded. Une préforme est produite plus efficacement et à moindre coût à partir de flocons de résine obtenus par broyage d'articles moulés en résine de polyester récupérés en flocons. Des flocons de résine obtenus par broyage d'articles moulés en résine de polyester récupérés en flocons sont préparés, et les flocons de résine sont plastifiés après traitement thermique sous pression réduite. Tout en éliminant la matière étrangère de la résine fondue obtenue par plastification des flocons de résine, la résine fondue est fournie à un dispositif de moulage par injection, et une préforme est moulée par injection. 回収されたポリエステル系樹脂成形品をフレーク状に粉砕してなる樹脂フレークから、より効率よく、かつ、より低コストで、プリフォームを製造する。回収されたポリエステル系樹脂成形品をフレーク状に粉砕してなる樹脂フレークを用意し、かかる樹脂フレークを減圧条件下で加熱処理した後に可塑化し、樹脂フレークを可塑化してなる溶融樹脂から異物を除去しつつ、溶融樹脂を射出成形装置に供給してプリフォームを射出成形する。
