A RAM press (or ram press) is a machine, invented in the USA in the mid-1940s, that is used to press clay into moulded shapes, such as 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.

History[edit]

The RAM Process was invented and patented in the mid-1940s by Keith Blackburn and Richard Steele, two ceramic engineering graduates from Ohio State University (OSU). Harold Dawson, another OSU graduate and co-owner of a small machining company, developed and built the first RAM Press shortly thereafter in Columbus, Ohio.

Blackburn and Steele licensed the RAM process and press for a decade, then sold their company to the Wallace Murray Corp. RAM Products Inc. of Columbus, Ohio was organized in 1979 and now manufactures the RAM press, as do other companies.

Other uses[edit]

The phrase ram press (in lower case) commonly means 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.
