Press forging is variation of drop-hammer forging. Unlike drop-hammer forging, press forges work slowly by applying continuous pressure or force. The amount of time the dies are in contact with the workpiece is measured in seconds (as compared to the milliseconds of drop-hammer forges).
The 50,000-ton press was the largest machine in the world at the time, 10 stories high and with foundations extending 100 ft (30 m) into bedrock. In 1983, the American Society of Mechanical Engineers designated the 50,000-ton forging press in North Grafton as a National Historic Mechanical Engineering Landmark. [6]
