- THE MAGAZINE For more than half a century, The RAM ProcessTM
has been used as a forming method in ceramic production
operations. Simply defined, the process entails the pressing of
moist clay into permeable molds (dies) that are mounted on
presses to form ceramic shapes. Gypsum cement (plaster) has been
commonly used to make these dies, but more permanent materials
have been developed and are being used today. Release of the
pressed shape from the die is accomplished by means of fluid
pressure (a combination of air and water) forced through the
die. The original concept, which was conceived and patented by
two ceramic engineers in Columbus, Ohio, was further developed
through the talents of a mechanical engineer who designed and
built a special press to complete the system. The three men
developed and added new features and improvements to the forming
method over the years. The invention and eventual patents for
The RAM Process incorporated the production of dies made from
specially prepared plasters using
