The Mesta Machine Company made large, and I daresay even huge, hydraulic forging presses for a great many years while they were in operation, and were widely used in industry. A while back I wrote a post about the 50,000 ton Mesta hydraulic forging press The “Fifty”, which was built several decades after the dinky little 8,000 ton steam-hydraulic press pictured above. Back in the day, however, an 8,000 ton forging press was a pretty big tool, and the largest that Mesta made at the time (circa 1919) was “only” 15,000 tons.
These machines were the workhorses of many forges through the years as the most efficient way of producing large forgings. I think that they’re wonderful.
The 1919 Mesta Product Catalog that is my primary source for this series of postings only has two pages concerning the large steam-hydraulic forging presses, which is pretty thin gruel by my standards, but while perusing the digital stacks of the Carnegie Library of Pittsburgh, I came across this interesting little pamphlet that I’ll share with you. Consider it a Boxing Day present if you will. The pamphlet’s title is: Steam-hydraulic presses for forging : shearing, flanging, bending, punching.
So there is your extra-large helping of Mesta machinery in the spirit of the season.
Except where noted, all images are from the 1919 edition of “Plant and product of the Mesta Machine Company, Pittsburgh, Pennsylvania“.
