Machine designed especially for the extrusion of clay materials of high  plasticity in regime of “soft extrusion”.

Vacuum extruder is appropriate for semi-wet process and for dry process. The maximum humidity of the material to treat and depending on its consistence curve and its adherence will be of 32-34%, thanks to its mechanical sturdiness and the optimization of all surfaces which work the clay are specially indicated to operate with low humidity (high pressure), doing fast and efficient the dry process, getting adjusted consumptions in the extrusion process.

The formation of laminations is a phenomena studied by Domenech during long time and we have found in this series of vacuum extruders the most stable and efficient solution. This solution is based on the pressure uniformity and in the reduction of the extrusion temperature in the vacuum chamber.
