What Makes HST’s 300kN High Frequency Fatigue Testing Machine a Game-Changer for Global Material Labs?
HST GROUP has launched its upgraded HST-PLG-300C 300kN High Frequency Fatigue Testing Machine, fully compliant with ISO 4965:1979 axial load dynamic force calibration standard, reshaping fatigue testing efficiency for aerospace, automotive and construction material R&D sectors worldwide.
This electromagnetic resonance-driven Testing unit delivers a frequency range of 50–285Hz, cutting energy consumption to merely 3% of traditional electro-hydraulic fatigue equipment. Built with a 4-column high-rigidity frame, it achieves force coaxiality better than 5% for precision-grade models, meeting strict calibration rules specified in ISO 4965:1979 for strain gauge dynamic force verification.
Equipped with optional hydraulic bending fixtures, CT specimen clamps and high-Low Temperature Chambers (-180℃ to 350℃), the High Frequency Fatigue Testing machine completes S-N curves, crack growth KIC and block spectrum fatigue tests on bolts, steel strands, composite alloys and engine connecting rods. Its independent DSP controller keeps testing running stably even when the connected PC malfunctions, with 10kHz high-speed sampling ensuring accurate real-time waveform recording.
Engineers from overseas automotive institutes noted the machine’s dual static-dynamic loading design drastically shortens long-cycle fatigue experiments. All hardware and software align with ISO 4965:1979, ASTM and Chinese national testing standards, making it a certified all-in-one solution for factory quality control and university fracture mechanics research. HST’s global sales team reports surging orders from European and Southeast Asian material testing laboratories.
