Synopsis

Excerpt from Die-Casting Machines: Hand-Operated and Automatic Machines for Making Pressure Castings 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 individuals efforts. Like most other industries, it has been of a gradual growth, through a period covering more than sixty years. The machines have been 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 The first 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. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
