摘要： The invention provides a resin-sealing apparatus that is operated with a low pressure and with a low clamping force without void generation and that is favorable for shortening the molding time and reduction of sealing resin consumption. In the resin-sealing apparatus of the present invention, a resin injection inlet of a pot has an opening at the center of the cavity surface of a cavity of a bottom mold that is a component of a mold unit, and a plunger for injecting molten resin in the pot from the opposite side to the resin injection inlet side is provided slidably and airtightly with the inside wall of the pot.

摘要： A multicolor molding method including: sandwiching, between a first cavity member having a through hole and a second cavity member, a substrate film on which an in-mold layer is formed so that the in-mold layer is positioned between the through hole and the second cavity member, the second cavity member closing one of openings of the through hole; disposing a core in a primary cavity formed of at least the through hole and injecting a first molding material into the primary cavity, to mold a primary molding layer on a surface of which the in-mold layer is transferred; and disposing the core in a secondary cavity and injecting a second molding material into the secondary cavity, to mold a secondary molding layer that covers the in-mold layer, the core being provided with the primary molding layer.
