Hydraulic Testing Machines

Italsigma designs and manufactures servo-hydraulic machines for static and dynamic testing.

Italsigma’s hydraulic machines are testing systems designed to perform static and dynamic tests on materials, components, and structures. Thanks to the high force generated by the hydraulic systems, they are ideal for high-load testing and fatigue testing on industrial and structural components.

The machines can be configured according to customer requirements and integrated with control systems, data acquisition systems, and specialized equipment.
