PURPOSE:To enhance the quality of a battery by injection molding a plastic frame between two metal sheets, thereby forming an armor case accommodation of a group of pole plates in such a way as in a single body, and depositing the plastic frame fast to the metal plates upon melting. CONSTITUTION:A group of pole plates consisting of a positive pole plate 2, negative pole plate 4, and a separator 3 are accommodated in an armor case consisting of two metal plates 1 pinching these pole plates and a frame formed around these two metal plates. A polyethylene fusion sprayed layer is furnished previously at the inner surface of each metal plate 1, and the plates are fixed fast to the frame 7. The two metal plates 1 pinching the pole plate group are put in a metal die 9, and plastic material is injected through a molding gate 11, and the frame 7 is formed around the two plates 1. This manufacturing process enhances the dimensional accuracy during manufacture, in which the frame and metal are deposited fast with each other and no extrusion is made to lead to enhancement of the quality. |
