BPD Low Pressure Casting Machine for Aluminum

The Ideal Low Pressure Casting Machine for serial production

The 4+8 column vertical press houses an independent dual mold motion system that allows the machine simultaneous or alternate casting through PLC control.


The large-capacity electric holding refractory furnace, with proportional pressurization control, is brought to working temperature by three heating elements protected by APM tubes made of sintered steel.

The casting ejection is hydraulically operated and 2 rotary arms catch the castings and remove them from the press by swiveling outwards, thus guaranteeing maximum safety for the operator.





Thermal control of the mold is achieved through a system of 8+8 separate circuits (air, water, or a mix) and PLC managed.


The switch and control cabinet and hydraulic pack complete the assembly.
