Laser welding of thin sheet metal materialLaser Welding

Dedicated to thin-sheet formed parts,
we achieve highly tight laser welding,
with Nishimura Quality.

We now possess a high-performance laser welding machine, which enables us comprehensive processing of products, including manufacturing of metallic separators, battery cells, and battery cases. Welded portions are subjected to a cross-sectional visual inspection, or are verified by a leak test, to ensure quality welded products.
