A vertical battery mould enables to produce air boxes with high quality finishings on all sides. This system ensures high performance on small working areas. Each formwork is made of several sets of vertical elements (side walls) built with high quality plates placed opposite to the casting and reinforced by steel sections in order to achieve a rugged structure able to counteract concrete pressure during the casting step. The battery mould may have one or two sectors unconnected to each other, each including casting compartments on the left and right sides of a fixed central module. Side walls are translated by means of a reliable hydraulic system that allows any compartment to be opened.
This equipment enables to produce air boxes of different sizes thus ensuring utmost production flexibility. Inner recesses provided for air circulation are realised by means of slightly conical cores, which can be extracted through hydraulic systems or simply through a tram crane.
Any coupling between formwork movable parts (such as at bottom/side walls) where there are opening and closing actions are provided with GF metal or rubber gaskets against the cement grout.
An efficient vibrator, whether pneumatic or electrical at variable frequency, combined with a specifically designed structure, ensures a rapid filling of the formwork and an optimum concrete compaction. Each battery mould can be also provided with a heating and insulation system to accelerate the concrete element’s curing process.
