DF-8000   Dynamic and Fatigue Testing Machine

Dynamic and Fatigue Testing Machine

DF-8000 dynamic fatigue testing machine is widely used for determining the durability of materials as metal, plastic, rubber and complex stuff. Utilize the cyclic tensile, compression or flexure strain under specified load, stroke and frequency to evaluate the material's service life cycle. This tester is driven by hydraulic power system. The actuator can be operated with various frequency and amplitude in order to perform tensile and compression fatigue test. DF-8000 dynamic fatigue testing machine is equipped with the high-speed controller and professional program. It is capable of generating waveforms such as sine, square and triangular or the waveform defined by users themselves. User is allowed to set up a test through the professional program with a variety of test method and condition to analyze the physical properties and quality of different materials.
