A method of forming and assembling a foldable plastic utility enclosure using molds to form sides of the enclosure, preferably using glass fiber-reinforced thermoplastic composite. The molds are constructed to form a central hole in hinge members which are formed on ends of the sides. The central hole of the hinge member is molded with two molding parts, wherein one or both of the molding parts have a solid central portion that forms the central hole. The sides are removed from the molds after curing and the sides are assembled to form the utility enclosure while the sides are still hot from the molding process. Hinge pins are inserted into the central holes of the hinge members to form hinges and to prevent the sides from warping during cooling. Assembling the sides and inserting hinge pins to form the utility enclosure is completed within approximately 10 minutes after removing the sides from the molds.

A method of forming a package is provided and includes providing two laminate edge portions of the package, each of which includes a foil layer between first and second resin layers; and welding together the respective first resin layers at a first position spaced apart from the edges while not welding the respective first resin layers at the edges, wherein the edge portions include edges from which electrode terminals extend such that portions of the electrode terminals are exposed beyond the edges, and wherein the edge portions are between a sealing portion and exposed portions of positive and negative electrode terminals.

An apparatus for manufacturing a secondary battery includes: a recess induction part configured to allow a folding part folded in a battery case of a secondary battery to be recessed inward so as to provide a recess part when the battery case of the secondary battery is folded; a first guide, of which one side of one end is recessed to define a concave space, wherein, when the battery case of the secondary battery is folded, the one end is configured to be inserted into the battery case to push the folding part to an outside so that the recess induction part is configured to be inserted into the concave space; and a second guide configured to hold a sealing part of the battery case so as to fix the battery case.
