Vertical pressing

Vertical presses - ultra-modern isostatic porcelain production

Please read our general explanation of isostatic pressing beforehand.

In the porcelain industry, Germany is not the only trendsetter in the development of high-tech process engineering. England has also been closely associated with "Chinaware" for many centuries through the Commonwealth. The patent for bone china, registered back in 1748, vouches for the British's historical claim to porcelain and ceramics.

BBC, an English manufacturer of high-performance machines for porcelain production, specialised in vertical pressing back in the late 1970s. These machine monsters work vertically inside their body - i.e. on edge - and usually produce with just one mould membrane (monopress). This technology was later also adapted by some German and European suppliers.

In contrast to the German machines (horizontal presses), vertical presses can also be used to produce items with large diameters - usually up to 34 cm. This very expensive and complex process is mainly used for large, round flat parts such as pizza plates. The raw material is not used moist as in other processes, but the vertical press works - like all isostatic systems - with dry granulate. If you stand in front of the machine, it is almost mystical how plate after plate is "spat out" by the monster at a constant, rhythmic interval.
