Sol′der-cast′ing.
A mode of making molten solder into sticks or drops for more convenient use.
In
Fig. 5288, the solder contained within a steam-heated block is expressed therefrom through the perforated bottom by the ram of a hydraulic engine.
The die is pierced with numerous holes of the form and size of the rods to be produced.
In
Fig. 5289, the reservoir containing the melted metal is hinged by a bar

to a standard on the frame, so as to be elevated when required.
The metal passes through an opening in the floor into the pockets of the periphery of the mold-wheel revolving beneath.

To make spindle-shaped drops, pour the melted solder into cold water at as low a heat as the metal will run. Pour a steady stream 1/8 inch in diameter from a hight of 3 inches above the water.
