THE DESIGN OF DIE-CASTING MACHINES
Die-castings have become fairly well known in the past few years, but
the machines, metals and methods employed in their manufacture are
as yet very little known. This is due no doubt to the fact that the

apparatus and methods employed have been zealously guarded as secrets
by those engaged in this manufacture. It may be surprising to many
to learn that the commercially successful manufacture of castings
from alloys in metal die-molds has not been accomplished through any
recent invention, nor been the result of any one individual's efforts.
Like most other industries, it has been of a gradual growth, through a

slowly perfected, and the alloys for the castings have been continually
improved. Thus it is now possible to make dense, sound die-castings
from alloys nearly as strong as brass, and a process by which a very
strong bronze can be cast in die-molds is being developed.
Historical

Development of Die-casting- Machines

machines or methods along this line were used to manufacture bullets and type. Many inventions for casting bullets were made
and several patents taken out in the years preceding and following the
American rebellion and the Mexican war.
Of the type-casting machines, the first one of which we can obtain
an illustration was patented on March 27, 1849, by J. J. Sturgiss. A
sectional view of this machine is shown in Fig. 1. This illustrates the
basic principle on which most of the die-casting machines in use to-day
are built. Tn this machine the molten metal flows from the pot A which
