A press for pressing powders and clays, has an electro-hydraulic control system to control a pressing ram and tool 14, a loading device 18 and an ejector ram and die, or ejector holding device 16, to fill, press and eject material from a body 10. The system responds to cams moved by the rams to actuate limit switches, and provide selectively presettable programmes for pressing cycles which start and finish with the rams in parking positions, provides an inching mode for setting up the limit switches, and provides for single cycle or automatic continuous cycling operation. The programmes include multiple filling of the body 10, double pressing and tamping the material, reciprocation of the loading device 16, pressing to thickness and pressing to density. <IMAGE> |
