Punch

The state-of-the-art grid production technologies include the punching system. Lead alloy is poured into large stripes and rolled.  Rolled stripes are gradually punched in the punch machine and transformed to grids. While the punch mould can be designed as desired, grid pattern can also be designed and shaped accordingly.

Therefore, custom-made grid designs which reduce the grid expansion and support active material retention can be manufactured.

Our company has invested in punching system and now manufactures grids for some special battery types using this method.
