Method for manufacturing in-mold coating product

A method for molding an in-mold coating product including a substrate and a coating formed on a surface of the substrate, the method comprising:

• closing a first mold including a fixed mold piece and a first movable mold piece to form a substrate cavity between the fixed mold piece and the first movable mold piece;
• charging the substrate cavity with a resin to form the substrate with a seal projection;
• closing a second mold including the fixed mold piece and a second movable mold piece in a state in which the substrate is arranged on the fixed mold piece to form a coating cavity between the surface of the substrate and the second movable mold piece, wherein the second movable mold piece has a seal projection deformation portion including a squeezer and a deformation absorber;
• deforming part of the seal projection with the second movable mold piece by squeezing the seal projection with the squeezer and absorbing deformation produced in the seal projection by squeezing out part of the seal projection into a region defined between the deformation absorber, the fixed mold piece, and the seal projection;
• and
• charging the coating cavity with a coating material to form the coating on the surface of the substrate.
