BPC Low Pressure Casting Machine for Aluminum

The LPM Low Pressure Casting machine with a Crucible Furnace

In this low pressure casting machine, the 4+4 column vertical press houses in its lower part a steel welded structure enclosing an electric, crucible-type holding furnace.   A proportional pressurization control on the crucible furnace affects the movement of the aluminum from the furnace to the dies during the low pressure casting process.

Working temperature is obtained by means of a series of heating elements that are fixed on 6 removable plates that embrace the outer structure of the crucible.

This system allows the furnace to maintain the working temperature even when only 5 elements are working, allowing the on-stream production to end.  Using this method of mounting the elements through the wall of the furnace,  the necessity to slide out the crucible when a faulty element requires replacement is eliminated.

The crucible furnace is mounted on a trolley allowing it to slide out frontally for ease of maintenance and crucible replacement.

A hoisting system driven by a hydraulic motor operates two screw jacks guided by four columns that allow lifting the furnace (up to 250 mm) to move it into its working position below the low pressure casting machine.
