Metal aids is a manufacturer of washers, such as zircon, graphite, magnesite [only alcohol] and aluminum silicate [only water] with both alcohol and water as carriers in powder, paste and ready to use form. The washers are high in their refractoriness quotient thus reducing the grinding losses and giving an excellent finish to the surface of the casting. This property ensures that the washers are of homogenous quality ensuring minimum human effort for mixing and application. They also ensure that irrespective of the kind of application procedure a foundry man applies the outcome will be an excellent finish to the casting. Good coverage enables the foundry manager to produce maximum number of castings with minimum quantity of washes thus reducing the effective cost of castings.
