Piston extruders

A class apart!

Our piston presses for the extrusion of ceramic and related masses are characterized by tailor-made design, use of the highest quality components such as hydraulic cylinder, hydraulic unit, control system, sensors and materials of the components coming into contact with the mass.
As our program is modular, piston presses with different diameters and lengths of the recipient/­cylinder can be derived from the types listed in the table at any time. In principle, all ECT-KEMA piston presses can be swiveled between 0-90˚, but can be supplied on request for horizontal, inclined or vertical extrusion angle only.
