Overview
The Hengyi HY-0580 Hydrogel Tensile-Compression Testing Machine is an electromechanical universal testing system engineered for high-fidelity mechanical characterization of soft biomaterials—particularly hydrogels—and other low-to-medium stiffness specimens including elastomers, polymers, foams, thin films, and biological tissues. It operates on the principle of controlled axial force application via a precision ball-screw-driven crosshead, with real-time acquisition of load, displacement, and optional extensometer-derived strain data. Designed for compliance with static mechanical testing standards—including ISO 527, ISO 6892-1, ASTM D412, ASTM D3574, ASTM F2118, and GB/T 228.1—the HY-0580 delivers traceable, reproducible results suitable for R&D labs, quality control environments, and regulatory submission packages under GLP or GMP frameworks.
Key Features
- Full-digital triple-closed-loop control architecture utilizing adaptive neural network algorithms for seamless switching among force, displacement, and strain control modes—ensuring zero overshoot and smooth transitions during multi-stage protocols (e.g., cyclic loading/unloading, stress-relaxation, creep).
- High-resolution load measurement system with internal resolution up to ±500,000 counts across the full range (1 N–5000 N); no range switching required, maintaining consistent resolution from 0.1% to 100% of full scale.
- Dual-speed motorized crosshead actuation (fast jog + fine positioning) with programmable acceleration/deceleration profiles to minimize inertial artifacts during low-force hydrogel testing.
- Integrated real-time visualization suite: simultaneous display of load vs. displacement, stress vs. strain, stress vs. time, and strain vs. time curves—all rendered in synchronized, multi-color overlay mode within a single coordinate system.
- Comprehensive safety architecture including electronic end-limit detection, hardware-based emergency stop circuitry, 110% overload cut-off, and automatic diagnostic self-checks for drive voltage, current, and sensor integrity at startup and during operation.
- Windows-native HYtest software supporting audit-trail-enabled operation per FDA 21 CFR Part 11 requirements when configured with user authentication, electronic signatures, and immutable data logging.
Sample Compatibility & Compliance
The HY-0580 accommodates specimens ranging from micro-scale hydrogel discs (Ø3–25 mm) to macro-scale polymer sheets and composite laminates. Standard fixtures include pneumatic flat-faced grips, wedge-action tensile clamps, compression platens, and custom-designed hydrogel-specific holders (e.g., porous stainless-steel mesh supports for swelling-controlled unconfined compression). Optional accessories include video extensometers (for non-contact strain mapping), environmental chambers (−40 °C to +150 °C), and humidity-controlled enclosures. All test methods align with internationally recognized mechanical testing standards: ISO 179-1 (flexural properties), ISO 604 (compressive properties), ASTM D638 (tensile), ASTM D790 (flexural), and ISO 13314 (compression of cellular materials). Data output formats comply with ASTM E1434 and ISO/IEC 17025 reporting guidelines.
Software & Data Management
HYtest v4.x is a modular, Windows-based platform offering full GLP/GMP support when deployed with role-based access control, electronic signature workflows, and tamper-evident audit logs. The software enables automated calculation of standard mechanical parameters—including ReH (upper yield strength), ReL (lower yield strength), Rp0.2 (0.2% offset yield), Rm (tensile strength), E (Young’s modulus), A (elongation at break), and relaxation/creep coefficients—based on user-defined analysis segments. Curve annotation tools allow manual or auto-detection of inflection points, yield onset, fracture initiation, and hysteresis loops. Export options include CSV, XML, PDF (with embedded metadata), and native .hys binary archives for long-term archival integrity. Batch processing supports sequence-driven multi-specimen testing with pass/fail criteria evaluation against pre-set tolerance bands.
Applications
- Hydrogel viscoelastic profiling: cyclic tensile-compression fatigue (up to 10⁵ cycles), stress-relaxation quantification, and time-dependent modulus decay modeling.
- Biomaterial scaffold evaluation: compressive modulus and collapse behavior of 3D-printed hydrogel matrices under physiological hydration states.
- Adhesive interface testing: peel, shear, and lap-shear strength of hydrogel-tissue or hydrogel-device bonds.
- Regulatory-grade QC: batch release testing of medical-grade hydrogels per USP and ISO 10993-10 biocompatibility mechanical assessment protocols.
- Academic research: constitutive model validation (e.g., Ogden, Mooney-Rivlin, Prony series) using high-temporal-resolution load-displacement histories.
FAQ
What load cell options are available for hydrogel-specific testing?
Standard configurations include 1 N, 5 N, 10 N, 50 N, and 100 N high-sensitivity load cells optimized for sub-mN resolution; custom low-range transducers (0.05 N full scale) are available upon request.
Can the system perform fully automated cyclic testing with variable amplitude and frequency?
Yes—HYtest supports programmable waveform generation (sine, triangle, square, ramp) with independent control over maximum/minimum load, cycle count, dwell time, and ramp rate per segment.
Is the software compliant with FDA 21 CFR Part 11 for regulated environments?
When deployed with server-based license management, user credentialing, and digital signature modules enabled, HYtest meets ALCOA+ data integrity principles and supports Part 11 compliance documentation packages.
Does the machine support third-party extensometers or DIC systems?
Yes—the controller provides TTL-sync outputs and analog/digital I/O ports compatible with commercial video extensometers and digital image correlation (DIC) hardware from Correlated Solutions, LaVision, or GOM.
What calibration documentation is provided upon delivery?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China), including as-found/as-left data for force, displacement, and speed axes, plus uncertainty budgets per ISO/IEC 17025 Annex A.
