摘要： A method of casting a casting product having tubular flow passages includes: attaching a cast-in pipe insert, having outer and inner fixing members to which both ends of pipes are coupled, respectively, to a fixed mold; assembling a movable mold with the fixed mold; injecting a molten metal into a cavity defined inside the fixed and movable molds; ejecting a casting product from the assembled molds after injecting the molten metal; and removing the outer and inner fixing members from the casting product.

摘要： A method for manufacturing a sandwich panel for a vehicle includes: etching a sheet, which etches one surface of a metal sheet; pressing the sheet, which forms a pattern of a specific shape on the one surface of the metal sheet; laminating a pair of the metal sheets; and performing injection-molding by injecting a plastic resin into the laminated pair of the metal sheets. The method may improve the bonding performance of the sandwich panel, thereby improving the degree of freedom of shape due to the press-molding.
