To improve a process and apparatus for pressing materials. ; SOLUTION: The invention relates to a process and apparatus for pressing materials in which a material is compressed by a piston that vibrates lengthways at an ultrasonic frequency to reduce the compression resistance of the material and to augment the compression effect; in practice, "static" compression, whereby an element is moved under the effect of pressure applied to it, is replaced by a succession of high-frequency blows; the process can be used in particular for squeezing materials of vegetable or animal origin in order to extract the juices from them and for manufacturing processes involving materials subjected to plastic deformation.
