固化押出し装置は知られている。(Prior art and its problems) Conventionally, there has been known a solidification extruder which melt-extrudes a thermoplastic synthetic resin, particularly a crystalline resin, and shapes the molten softened resin into a predetermined shape under a back pressure.
上記固化押出し装置は、フォーマに組み込まれている
加熱ブロックの加熱媒体導入孔を、押出し方向に直交配
列したものは知られている。As the solidification extrusion device, there is known one in which heating medium introduction holes of a heating block incorporated in a former are arranged orthogonally to the extrusion direction.
