  • Publication number: 20240170814
    Abstract: A method for producing a power storage device includes an insert-molding step of making a resin member by insert-molding with respect to a terminal member inserted in an insertion hole of a lid. In this insert-molding step, the insertion hole of the lid is placed in front of a gate, and a molten resin is injected through the gate to flow in an opposite gate-side space in a cavity through the insertion hole, allowing the molten resin to spread over the entire cavity, to form the resin member.

  • Publication number: 20240170816
    Abstract: A method for producing a power storage device includes a process of insert-molding. This process is to relatively move a first mold and a second mold to press a terminal top surface of a terminal member by a top-face close-contact portion of the first mold to a second-mold side and to press a to-be-contacted portion of the terminal member by a contact portion of the second mold to a first-mold side so that a deformed portion of the terminal member is elastically deformed. A resin member is thus insert-molded while the terminal top surface is pressed and tightly contacted with the top-face contact portion.
