The VOLT Casting machine, type CAST2A, is specially designed for high productively and for the casting of lightweight alloy grids in low resistance, radial and center bias lug designs for MF & VRLA batteries.  Fast, reliable and rugged construction for continuous 3-shift production. This machine incorporates the most advanced features in grid castings.

lAccurate temperature control of the up and down parts of the mold: the control is carried out by water cooling on multiple lines and by thermostatically controlled electric heaters. The tilting plate and the trim die are also water cooled.

lAccurate alloy casting control : the alterative are conventional lever pots, with rotary pump, and raised pots with gravity feeding. In  both cases the quantity of lead is metered by special valves..

lAway oxidation: closed pouring ladle with electric heating and oxidation-preventing flames, lead drop eliminator is provided for the alloys specially in calcium lead alloy.

l Recycling system for the mold cooling fluid: utilizing and automatic temperature regulator provided with heating and cooling systems. It ensures constant casting conditions and at the same time eliminates lime deposits inside the cooling ducts. Regulation of the mold conditions also continues when the machine stops.

High productivity: the ladle and the stacker are separately equipped  with water-cooling and fan-cooling.
