Abstract

An insert member (100) heated by a heating device (13) is conveyed, by means of a conveyance device (12), into a mold (51). Next, shaping is performed on the insert member (100) inside the mold (51), with the mold (51) being open by a minute distance. A molding material (91) is injected into the mold (51) and pressed while closing the mold (51) which has been open by the minute distance to thereby mold a molded article (80) including the insert member (100).

First claim

The invention claimed is:

1. A molded article manufacturing method comprising:
conveying, by use of a conveyance device, a thermoplastic prepreg, heated by a heating device, into a mold including a stationary die and a movable die;
shaping the thermoplastic prepreg inside the mold, with the mold being open by a distance, where the distance between the movable die and the stationary die is 0.5 to 3 mm; and
injecting a molding material into the mold and pressing while closing the mold which has been open by the distance to thereby mold a molded article including the thermoplastic prepreg.

2. A molded article manufacturing method comprising:
conveying, by use of a conveyance device, a thermoplastic prepreg, heated by a heating device, into a mold including a stationary die and a movable die;
shaping the thermoplastic prepreg inside the mold; and
afterwards opening the mold to a degree, where the degree between the movable die and the stationary die is 0.05 to 3 mm, and injecting a molding material into the mold to thereby mold a molded article including the thermoplastic prepreg.

3. A molded article manufactured by the molded article manufacturing method according to claim 1 .

4. A molded article manufactured by the molded article manufacturing method according to claim 2 .
