Slip Casting
Battery Casting in Plaster Moulds
Battery casting is a better method when compared to Bench Casting. The productivity in this method is greater and can be achieved with relatively low mould cost. The space requirement for this method is lesser. More pieces can be produced within the space available, which reduces capital requirements compared to bench casting methods. Skills required to produce ware is lower than bench casting. Wares can be produced with fewer skills.
The disadvantages of this method is that the Mould life is short, and larger runs of the same items are usually required because the speed with which the moulds are turned over naturally produces more wear. Additionally, while moulds are made of plaster, the mould-making methods are not traditional and require the interconnection of several mould parts to form a single, larger assembly (with bench casting the moulds are not interconnected). Lavatories tend to be the most favoured piece for gang casting because they are more easily gang-cast as a group.
