Overview
The Hengyi HY-0580BNF High-Precision Short-Fiber Mechanical Testing System is an electromechanical universal testing platform engineered for static and quasi-static mechanical characterization of biomaterials, medical devices, and advanced polymeric composites. It operates on a servo-controlled linear actuation principle, delivering precise axial force application and displacement control in tension, compression, bending, shear, peel, puncture, and pull-out modes. Designed specifically to meet the stringent requirements of biomedical R&D and regulatory preclinical validation, the system supports standardized test protocols aligned with ISO 5832, ASTM F2193 (for bone screws), ASTM F1717 (spinal implants), ISO 13314 (compression of cellular materials), and USP (mechanical testing of tissue-engineered products). Its modular load cell architecture—supporting interchangeable transducers from 1 N to 5 kN—enables traceable force measurement across six orders of magnitude without range switching or resolution loss.
Key Features
- High-fidelity dual-closed-loop control: Simultaneous real-time regulation of load, displacement, and strain via independent PID tuning per channel.
- Ultra-fine displacement resolution: 0.001 mm over full 800 mm stroke, enabling accurate quantification of micro-deformations in soft hydrogels and thin electrospun fiber mats.
- Multi-range calibrated load cells: Twelve selectable nominal capacities (1 N–5 kN), all certified to ISO 7500-1 Class 0.5 accuracy, with internal 500,000-count A/D conversion and no internal range switching.
- Programmable test sequencing: Up to 100-step profiles supporting ramp-hold-relax cycles, cyclic fatigue (1–5 Hz equivalent via stepwise loading), and conditional termination (e.g., stop at 10% strain, 500 N load, or 300 s duration).
- Integrated safety architecture: Dual-redundant electronic limit switches, overload cutoff (>110% FS), automatic return-to-home post-test, and real-time self-diagnostic monitoring of drive current, voltage, and thermal status.
- Ergonomic sample handling: Motorized crosshead with coarse/fine speed selection, manual jog control, and quick-release clamping fixtures compatible with ASTM D3039, ISO 527-2, and ISO 6892-1 specimen geometries.
Sample Compatibility & Compliance
The HY-0580BNF accommodates heterogeneous specimen types—from sub-millimeter synthetic sutures and electrospun PCL fibers to orthopedic implants (cortical bone screws, interbody cages, intramedullary nails) and hydrated biological tissues (porcine aorta, bovine tendon, decellularized dermis). Its 120 mm effective test width and 800 mm vertical clearance support custom fixture integration, including pneumatic grips for low-force textile fibers, wedge-action clamps for high-strength composites, and specialized articulating fixtures for joint simulator alignment. All hardware and firmware comply with IEC 61000-6-2/6-4 EMC standards; data acquisition meets ALCOA+ principles for audit readiness under GLP and GMP environments. Optional digital signature and electronic audit trail modules satisfy FDA 21 CFR Part 11 requirements for regulated biocompatibility studies.
Software & Data Management
The system ships with Hengyi TestMaster v4.x—a Windows-based control and analysis suite supporting multi-language UI (English, German, Japanese), automated report generation (PDF/Excel), and raw data export in CSV and MATLAB-compatible formats. Calibration certificates are digitally embedded and linked to each load cell’s unique ID. Software features include real-time stress–strain curve overlay, modulus calculation (tangent, secant, chord), yield point detection (0.2% offset, ISO 6892-1), fracture energy integration, and Weibull statistical analysis for strength distribution modeling. All test parameters, operator IDs, timestamps, and environmental logs (temperature/humidity metadata) are stored in a relational SQLite database with configurable backup intervals and role-based access controls.
Applications
- Mechanical validation of resorbable polymer scaffolds (PLGA, PCL, collagen-glycosaminoglycan matrices) under uniaxial tension and cyclic loading.
- Static and dynamic testing of cardiovascular devices: stent radial strength, heart valve leaflet flexural fatigue, vascular graft suture retention.
- Orthopedic implant certification: screw pullout resistance in synthetic bone blocks (Sawbones®), plate bending stiffness, fusion cage compressive yield.
- Soft tissue biomechanics: tensile testing of skin substitutes, burst pressure of tissue-engineered bladders, viscoelastic relaxation of corneal lamellae.
- Industrial quality control: tensile strength of aramid reinforcement fibers, interlaminar shear of carbon-fiber laminates, peel adhesion of medical-grade pressure-sensitive adhesives.
FAQ
What standards does the HY-0580BNF support for medical device testing?
It natively supports test method scripting for ISO 13314, ASTM F2193, ASTM F1717, ISO 5832-3, and USP , with customizable parameter templates for regulatory submissions.
Can the system perform cyclic fatigue tests?
Yes—within its 0.001–500 mm/min speed range, it executes controlled displacement- or load-controlled step-cycle sequences up to 10⁵ cycles; true sinusoidal waveforms require optional dynamic actuator upgrade.
Is calibration traceable to national standards?
All load cells are factory-calibrated against NIM (National Institute of Metrology, China) reference standards, with optional UKAS-accredited calibration available upon request.
What sample gripping solutions are included?
Standard configuration includes pneumatic flat grips (0–5 kN) and self-tightening wedge grips (1–5 kN); custom fixtures for small-diameter fibers (<100 µm) and irregular implants are available as accessories.
Does the software support multi-user environments with audit trails?
Yes—TestMaster v4.x provides configurable user roles, electronic signatures, immutable audit logs (per 21 CFR Part 11), and encrypted database backups with timestamped revision history.
