A mold that punches the shape of the TAB part and the BOTTOM part (Flat) of the electrode at once
1, 2, 3, 4 Cavities can be implemented depending on the electrode shape
(Mold that can be punched from 1 to 4 electrodes per punching)

It is a mold that punches the TAB and BOTOM parts like a regular Notching mold, but the mold of the TAB part is separated into two, so the width of the mold is changed freely and used for R&D

A mold that punches four sides of the electrode in one stroke
Since the scrap part of the product becomes a used electrode, it is lower in quality than the Notching mold, but because it can produce a large amount of samples at a low cost, it is used for R&D
