Document Type and Number:

WIPO Patent Application WO/2017/160030

Kind Code:

A1

Abstract:

The present invention provides a battery case manufacturing device comprising: a first mold having a first space of a shape corresponding to a storage part; a second mold having a second space of a shape corresponding to the storage part, and a through-hole communicating with the second space, and configured so as to couple with the first mold by putting a laminate sheet therebetween; and an air pressure regulator mounted in the through-hole in a state in which the first space and the second space are isolated from the outside, and increasing and decreasing the air pressure of the second space through the through-hole so as to elongate and deform the laminate sheet into a shape corresponding to the first space or the second space.
