The objective in grid casting is to maintain the mould temperature constant both from one cast to the next and throughout the working shift. The temperature of the mould, particularly the moving half, depends on the external heating source plus the heat transferred from the molten metal poured into the mould.
In contrast, casting a grid from the molten alloy did not require complicated or costly equipment, all trimmings could be returned to the lead alloy furnace and the moulds were not expensive to buy or difficult to make. Because of these attributes, casting grids has remained the main grid-making system.
Components of an automotive battery grid There have been many designs of grids adopted over the years based on the lattice principle. In this, the horizontal members are approximately half the thickness of the grid and half that of the rib cross section.
Expanded metal grid production involves mechanical operations on the cast strip and is not a source of airborne lead dust or oxide. The major source of lead exposure in this process is from lead fumes and lead oxide which can become easily airborne.
