Verfahren zum Herstellen einer Rolle |
摘要 |
A method of manufacturing a roller includes: forming a hollow cylindrical body that includes a fully solidified outer peripheral surface and a semi-solidified interior, with an inner peripheral surface swelling inwardly; and pressing the swollen portion of the inner peripheral surface outwardly by pulling an insert die from the semi-solidified cylindrical body, to thereby allow the outer periphery of the cylindrical body to swell outwardly in a barrel-like manner. A primary molded product including a through hole along a central axis is thereby formed, and a secondary resin is injected into the through hole of the primary molded product. |
