A method for manufacturing a fiber-reinforced resin part, the method comprising: positioning a plurality of fibers (210; 410; 510) on a mold surface (204; 404; 504) of a tool (202; 402; 502; 702); covering the fibers (210; 410; 510) with a sealing layer (220; 420; 520); pressing a portion of the covered fibers (210; 410; 510) against an interior transition region (206a, 206b; 406; 506) of the mold surface (204; 404; 504) with a pressing device (234; 434; 534); and while pressing the portion of covered fibers (210; 410; 510) against the interior transition region (206a, 206b; 406; 506), removing air from between the sealing layer (220; 420; 520) and the mold surface (204; 404; 504) to draw at least a partial vacuum between the sealing layer (220; 420; 520) and the mold surface (204; 404; 504), wherein pressing a portion of the covered fibers (210; 410; 510) against an interior transition region (206a, 206b; 406; 506) with a pressing device (234; 434; 534) includes moving the pressing device (234; 434; 534) toward the portion of covered fibers (210; 410; 510) to compress the portion of covered fibers (210; 410; 510) between the pressing device (234; 434; 534) and the interior transition region (206a, 206b; 406; 506), and wherein the method further comprises moving the pressing device (234; 434; 534) away from the portion of covered fibers (210; 410; 510) and removing the pressing device (234; 434; 534) from the tool (202; 402; 502; 702) after drawing at least a partial vacuum between the sealing layer (220; 420; 520) and the mold surface (204; 404; 504) and before curing resin infusing the plurality of fibers (210; 410; 510). positioning a plurality of fibers (210; 410; 510) on a mold surface (204; 404; 504) of a tool (202; 402; 502; 702); covering the fibers (210; 410; 510) with a sealing layer (220; 420; 520); pressing a portion of the covered fibers (210; 410; 510) against an interior transition region (206a, 206b; 406; 506) of the mold surface (204; 404; 504) with a pressing device (234; 434; 534); and while pressing the portion of covered fibers (210; 410; 510) against the interior transition region (206a, 206b; 406; 506), removing air from between the sealing layer (220; 420; 520) and the mold surface (204; 404; 504) to draw at least a partial vacuum between the sealing layer (220; 420; 520) and the mold surface (204; 404; 504), wherein pressing a portion of the covered fibers (210; 410; 510) against an interior transition region (206a, 206b; 406; 506) with a pressing device (234; 434; 534) includes moving the pressing device (234; 434; 534) toward the portion of covered fibers (210; 410; 510) to compress the portion of covered fibers (210; 410; 510) between the pressing device (234; 434; 534) and the interior transition region (206a, 206b; 406; 506), and wherein the method further comprises moving the pressing device (234; 434; 534) away from the portion of covered fibers (210; 410; 510) and removing the pressing device (234; 434; 534) from the tool (202; 402; 502; 702) after drawing at least a partial vacuum between the sealing layer (220; 420; 520) and the mold surface (204; 404; 504) and before curing resin infusing the plurality of fibers (210; 410; 510).
