In technical ceramics, hydraulic presses are used to produce ceramic components – with uniform density and great lengths, as well as small, complex component geometries. Depending on physical properties or optical characteristics the pressed part should have, a difference is made between two pressing processes, the
axial pressing
and the isostatic pressing.
Both isostatic and axial ceramic pressing are technologies that uses high pressure to compact ceramic powder, it transforms the material from a loose powder into a green part.
After the creation of the green part, the pressed part has to go through a few more steps until the end product is created – these can be sintering processes, turning and milling operations or sizing presses.
In the video you can see some of those green parts.
