Battery Tooling We use our advanced ceramic materials to make high performance tooling for the production of zinc carbon dry cells and alkali batteries, including mixer units, extruders, liners, nozzles, ram tips, sweeper blades, dies and punches. The parts are made using Nilcra Zirconia, an advanced ceramic material that is strong, tough and highly resistant to the corrosive battery mix. It is a good choice because it is a consistent, reliable material (Weibull Modulus > 30) with a low coefficient of friction. Abrasive materials have minimal effect on its surface.
