Hydraulic Pressing
- The press operator places "throwable" clay into the mold and the two halves come together and press the excess clay from between the top and bottom molds. The blank space between the two halves of the molds is the negative space left by the model, and is now filled with wet clay. Air pressure forced through the plaster molds releases the item from the plaster. That enables the press to be cycled as often as 5 times per minute, and the molds never become water logged. That enables runs of 500 or more in one working day. -
