Pressing: Preliminary step and Manufacturing process
Pressing is a technique that can be used both directly to produce the finished ceramic product and as a preliminary forming stage ahead of another production process.
Uniaxial pressing or Isostatic pressing
As its name indicates, with uniaxial pressing the force is applied in a single axial direction. It can be used to obtain finished parts, however, these parts must be very simple, small and with relaxed dimensional tolerances.
Isostatic pressing is usually used to complement uniaxial pressing. The aim is to produce a more highly-pressed product whose firing-induced shrinkage is easier to control.
It can also be used to form simple parts such as discs, bars or tubes.
