Continuously cast and expanded grids were produced by means of the TeckCominco Multi-alloy Caster. The alloy is held at 400 C and the cooling drum at 40 C.The strip is cast at a rate which depends on its thickness, i.e. about 19 m min −1 for 0.95-mm thick strip for positive grids, and about 21 m min −1 for 0.75-mm thick strip for negative grids.
At present, when manufacturing battery plates, there are usually two ways, one is to use a casting machine for casting, and the other is to use a punch to punch the lead plate.casting technology is mostly used in many factories to make battery plates compared to punching technology.
