Nishimura Mfg. (NS Slitter)

It designs, builds and maintains machines to each customer's specification for paper, film, non-ferrous foil and electronic materials, controlling slitting method and unwind-rewind tension to give clean cut edges and well-wound rolls. Its machines are used for packaging films, aluminium foil, adhesive tapes, display films, capacitors and lithium-ion battery materials for smartphones and electric vehicles.
