RAM press
From Wikipedia, the free encyclopedia
A RAM press (or ram press) is a machine, invented in the USA in the mid-1940's, that is used to press clay into moulded shapes, such as into plates and bowls. In operation a slice of de-aired clay body is placed in between two shaped porous moulds, and vertical movement of the moulds presses the body into the required shape.
[edit] History
The RAM Process of molding was invented and patented by two ceramic engineering graduates from Ohio State University (OSU) in the mid-1940's, Keith Blackburn and Richard Steel. Harold Dawson, another OSU graduate and co-owner of a small machine shop, developed and built the first RAM Press shortly thereafter in Columbus, Ohio.
Blackburn and Steel licensed the RAM process and press for a decade, then they sold their company to the Wallace Murray Corp. Finally, RAM Products Inc. of Columbus, Ohio was organized in 1979 and now manufactures the RAM press.
[edit] Other uses
The phrase ram press (in lower case) is also commonly in published sources to mean the same thing, it is simply used for machines that press items by a mechanical ram, such as with a plunger, piston, force pump, or hydraulic ram. See also press.
