Hengyi HY-30080TYU 300 kN Electromechanical Universal Testing Machine

Overview

The Hengyi HY-30080TYU is a high-capacity, electromechanical universal testing machine engineered for precision static mechanical property evaluation of metallic and non-metallic materials—including composites, alloys, structural steels, aluminum extrusions, and advanced engineering polymers. Based on servo-controlled electromechanical actuation and closed-loop digital feedback architecture, the system applies controlled uniaxial tensile, compressive, flexural, shear, peel, tear, creep, stress relaxation, and cyclic loading protocols in accordance with ISO 6892-1, ASTM E8/E21, EN 10002-1, GB/T 228.1–2021, and other internationally harmonized standards. Its 300 kN (30-ton) load frame features a rigid double-column龙门 (gantry) structure with reinforced crosshead guidance, ensuring minimal deflection and high axial alignment fidelity during high-force testing—critical for accurate modulus, yield strength (ReH, ReL), proof stress (Rp0.2), ultimate tensile strength (Rm), fracture elongation (A), and Young’s modulus (E) determination.

Key Features

• High-precision force measurement system compliant with ISO 7500-1 Class 0.5, delivering resolution up to 1 part in 500,000 full-scale counts without range switching
• Full-range adjustable test speed from 0.001 to 500 mm/min, with closed-loop velocity control accuracy maintained within ±0.5% of setpoint
• Integrated displacement and strain measurement subsystems, each calibrated per ISO 9513 and GB/T 12160–2002, achieving ±0.5% accuracy across the entire stroke
• Dual-mode control architecture supporting stress-rate, strain-rate, and displacement-rate regulation—enabling precise execution of ASTM E2309-compliant ramp-hold and multi-step loading profiles
• Intelligent safety framework including electronic limit switches, overload protection (110% FS cutoff), real-time diagnostic monitoring of drive electronics, power supply, and sensor integrity
• Modular load cell configuration supporting interchangeable transducers from 1 N to 300 kN, facilitating seamless transition between micro-scale and structural-scale testing regimes
• Motorized crosshead with dual-speed (fast/slow) jog control and programmable auto-return functionality—reducing operator intervention and enhancing throughput consistency

Sample Compatibility & Compliance

The HY-30080TYU accommodates specimens ranging from thin foils (<0.1 mm thickness) to heavy-section billets (up to Ø120 mm diameter or 150 mm square cross-section), enabled by its 600 mm wide test zone and 800 mm vertical clearance—both field-expandable. Standard grips include wedge-action hydraulic clamps, pneumatic vise jaws, and custom-threaded fixtures for threaded rods or fasteners. The system complies with mechanical verification requirements per ISO 7500-1, ISO 5893, and GB/T 16491–2008 (successor to GB/T 16491–1996), and supports validation under GLP and GMP environments through traceable calibration documentation and audit-ready event logging. All software-generated reports embed metadata required for FDA 21 CFR Part 11 compliance when paired with optional electronic signature modules.

Software & Data Management

Equipped with Hengyi’s proprietary TestMaster Pro v5.x control and analysis suite, the system delivers real-time acquisition at ≥1 kHz sampling rate, synchronized force-displacement-strain-time data streams, and automated parameter extraction per ASTM E111, ISO 6892-1 Annex A, and GB/T 228.1–2021 Annex B. The software supports user-defined test templates, multi-curve overlay, statistical batch reporting (mean, SD, CV%), and direct export to CSV, PDF, XML, and MRP-compliant formats. Audit trails record all operator actions, method changes, calibration events, and system diagnostics with time-stamped, immutable entries—fully compatible with laboratory quality management systems (QMS) requiring ISO/IEC 17025 traceability.

Applications

• Tensile characterization of aluminum alloys (e.g., 6061-T6, 7075-T73) per ASTM B557 and GB/T 228.1
• Compression testing of cast iron, titanium ingots, and sintered metal powders per ASTM E9 and GB/T 7314
• Three-point bending evaluation of welded joints and composite laminates per ASTM D7264 and GB/T 14452
• Creep and stress relaxation studies on high-temperature superalloys under ISO 204 and GB/T 15248
• Quality assurance of fasteners, springs, and structural connectors per ISO 898-1 and GB/T 3098.1
• R&D validation of additive-manufactured metal parts, including porosity-sensitive fatigue pre-screening via controlled monotonic loading

FAQ

What international standards does the HY-30080TYU support for tensile testing?

It fully implements ISO 6892-1, ASTM E8/E21, EN 10002-1, and GB/T 228.1–2021, with built-in calculation routines for ReH, ReL, Rp0.2, Rm, A, Z, E, and n-value (strain hardening exponent).
Can the system perform closed-loop strain-controlled tests?

Yes—it supports real-time strain-rate control down to 0.002% FS/s using extensometer feedback, meeting ASTM E2309 and ISO 6892-1 requirements for low-strain-rate applications.
Is third-party calibration certification available?

Hengyi provides factory calibration certificates traceable to CNAS-accredited national metrology institutes; optional UKAS or DAkkS-certified calibration services are available upon request.
How is data integrity ensured for regulated environments?

TestMaster Pro includes role-based access control, electronic signatures, tamper-evident audit logs, and 21 CFR Part 11-compliant electronic records when configured with secure authentication and timestamping modules.
What maintenance intervals are recommended for long-term accuracy?

Annual verification per ISO 7500-1 is advised; biannual inspection of grip surfaces, alignment checks, and drive system lubrication are included in the preventive maintenance schedule provided with delivery.
