Servo-Hydraulic Static Universal Testing Machines

Servo-Hydraulic Static Universal Testing Machines

Once the load runs into hundreds of kilonewtons, a hydraulic actuator carries it more comfortably than a ballscrew. Servo-hydraulic static frames apply and hold force through a closed loop, which keeps the rate steady on stiff specimens: structural steel, rebar, fasteners, castings and welded joints. NextGen builds these frames for tension, compression and flexure, working to ASTM E8 and ISO 6892 for metals.

Each system is configured as a whole rather than assembled from parts: frame capacity, hydraulic power unit, grips and fixtures sized for the specimen, extensometry and method software. Machines are installed and calibrated on site by our engineers, your operators are trained on both the hydraulics and the software, and support continues for the life of the frame.

For Laboratories

One partner to equip your complete metals laboratory

Servo-hydraulic frames cover the high-force end of a metals laboratory. NextGen equips the rest of it too, from grips and fixtures to electromechanical frames, impact testing, hardness and metallography, and stays responsible for it after delivery.

FAQs

Here are some fundamental differences between Class A and Class DP Servo Hydraulic Universal Tensile Testers:

  1. Class A can only perform tension or compression test, while Class DP can perform tension and compression cyclical test.
  2. Class DP is much heavier system than Class A. It is a robust machine equipped with a heavier bottom platen and top platen. It also has a much larger cylinder.
  3. Class DP tensile tester uses I type load cell. This is an more advanced, precise and reliable load cell relative to Class A system.
  4. During specimen clamping Class DP Servo Hydraulic machine has smaller initial force than Class A. That means that Class DP has smaller rate of damage on specimens during clamping.
  5. Class DP system is shock absorbent allowing for a minimum ground shock upon tensile specimen break.
  6. Class DP is easier for tensile testing in general. It is more user friendly, accessible and accurate. When it comes to Class A tensile tester, the operator needs to use a small ladder when loading the specimens, because the tensile test space is in the upper section of the tester.
