Abstract: PROBLEM TO BE SOLVED: To accurately control the pressure and quantity of a resin with which a cavity is packed in manufacturing a molded cylindrical body having a tapered part. SOLUTION: A fixed mold has a moving body 46 movable with respect to a base metal 38. Molds are clamped with a weak clamping force, and a cavity 34 is packed with a resin.

Then, the molds are clamped with a strong clamping force to close the base metal 38 and the moving body 46. According to this operation, the resin in the cavity 34 is returned to the molding machine side.  A protruding part 58 of the base metal 38 is fitted into a recessed part 81 of the movable mold 33, and at a point of time when a gate 87 is closed, a fixed quantity of the resin remains in the cavity 34. Thereafter, the resin remaining in the cavity 34 is compressed. Accordingly, a thin-wall tapered part can be reliably formed without any defects by compression after the packing.
