  • Patent number: 8979950
    Abstract: A sealing method for battery containers which employs a first fixture to engage with the outer peripheries of edges of an opening of a container made from metal sheets, in order to define a shape of the opening of the container; then a second fixture is inserted into an inner space of the container from its opening, so that the edges of the opening of the container are shaped due to the ductility and malleability properties of metal sheets, and lateral surfaces of the container are made flat; lastly, a cover is placed on the opening of the container to have the container sealed by a welding means. The sealing method can restore an original shape of the container from a deformed state by using the fixtures, so that an entire sealing process for battery containers can be executed by automation in order to save labor costs.
