By certification 
Equipped with appropriate fixtures, the testing machine can perform various tension and compression tests such as compression, bending, shearing, rigging tension, and bolt tension. At the same time, the tensile testing machine can also obtain the tensile strength, yield strength, specified non-proportional elongation strength, elastic modulus and other performance indicators of the tested material, and can realize closed-loop control of equal rate loading, equal rate deformation, equal rate displacement, etc. It can be used to verify the process qualification performance of materials or products.

1) The German Rexroth intelligent variable high-pressure oil pump is used to supply oil on demand, with intelligent adjustment, almost no overflow, and little heat generation. It is suitable for long time static or low frequency fatigue test.
2) Low noise, below 50 decibels under the highest working load.
3) The pressure follower saves 70% energy than conventional equipment
4) The control precision is high, and the control precision can reach one ten thousandth. (normally five thousandths)
5) There is no control dead zone, and the starting control point can reach 1%.
6) The oil circuit is highly integrated, and there are few leakage points.
