Hengyi HY-0580mbgf Single-Column Electromechanical Universal Testing Machine for Conductive Fibers

Overview

The Hengyi HY-0580mbgf is a single-column electromechanical universal testing machine engineered for high-precision mechanical characterization of low-to-medium force materials—particularly conductive fibers, textile filaments, thin polymer films, and miniature composite specimens. It operates on the principle of controlled displacement actuation via a precision ball-screw-driven crosshead, coupled with real-time force feedback from calibrated S-type or cantilever load cells. Unlike hydraulic systems, its servo-motor-driven architecture ensures repeatable, low-noise force application across sub-newton to 5 kN ranges—critical for evaluating brittle fracture onset, interfacial adhesion in fiber-reinforced composites, and strain-dependent conductivity transitions in electroactive textiles. Designed for laboratory and QC environments where space efficiency and rapid setup are essential, the HY-0580mbgf complies with fundamental metrological requirements defined in ISO 7500-1 (static calibration of force-proving instruments), ASTM E4 (load verification), and ISO 5893 (tensile testing machines). Its modular mechanical design supports seamless integration with environmental chambers, video extensometers, and custom grips—enabling full traceability under GLP/GMP-aligned workflows.

Key Features

• Single-column rigid frame with aluminum alloy upright and hardened steel crosshead—optimized for minimal deflection (<0.02 mm/kN) during axial loading
• High-resolution force measurement system: ±500,000 internal counts, no auto-ranging, constant resolution across full scale (1 N to 5000 N)
• Wide dynamic speed range: 0.001–500 mm/min, programmable in 0.001 mm/min increments; closed-loop velocity control maintains ±0.5% accuracy per ASTM E83
• Dual-mode motion control: manual jog for rapid positioning + automated sequence execution via PC interface
• Integrated safety architecture: electronic limit switches, overload cutoff (>110% FS), real-time diagnostic monitoring of motor current, drive voltage, and sensor signal integrity
• Modular grip compatibility: standardized T-slot base accepts wedge, pneumatic, vise, and custom fiber-clamping fixtures—including low-slip carbon-fiber-faced jaws for conductive yarns
• Self-aligning load train geometry minimizes bending moments during tensile tests per ISO 527-1 Annex B

Sample Compatibility & Compliance

The HY-0580mbgf accommodates specimens up to 120 mm wide and 800 mm gauge length, supporting standardized geometries per ISO 527 (plastics), ISO 20795-2 (dental polymers), GB/T 3923 (woven fabrics), GB/T 1040 (tensile properties of plastics), and ASTM D3822 (single-filament tensile testing). Its low-force capability (1 N minimum capacity) enables accurate measurement of Young’s modulus and breaking tenacity in conductive nanofibers, carbon nanotube yarns, and PEDOT:PSS-coated textiles—where conventional machines lack resolution. All mechanical components meet RoHS Directive 2011/65/EU material restrictions. Calibration certificates conform to ISO/IEC 17025 requirements when issued by accredited third-party labs. The system supports audit-ready documentation for FDA 21 CFR Part 11 compliance when paired with validated software modules (e.g., optional electronic signature, change history logging, and user-access controls).

Software & Data Management

Control and analysis are performed via Hengyi’s proprietary TestMaster Pro software—compatible with Windows 10/11 (64-bit) and supporting multi-language UI (English, Chinese, Spanish, German). The software implements ASTM E1391-compliant test method templates for tensile, peel, shear, and cyclic loading protocols. Raw data streams (force, displacement, time, extension) are recorded at ≥1 kHz sampling rate and stored in ASCII CSV and binary .hdt formats for third-party post-processing (MATLAB, Python Pandas, OriginLab). Built-in statistical tools calculate mean, SD, CV%, Weibull modulus, and confidence intervals per ISO 2602. Audit trails record all operator actions, parameter changes, and calibration events with timestamped user IDs—fully exportable as PDF reports with digital signatures. Optional API access allows integration into LIMS platforms via RESTful endpoints.

Applications

• Mechanical-electrical coupling analysis of conductive fibers under uniaxial strain (resistance vs. elongation)
• Tensile strength and elongation-at-break evaluation of melt-spun PAN-based carbon precursor fibers
• Interfacial shear strength (IFSS) determination in fiber-matrix microcomposites using microbond or fragmentation tests
• Creep and stress-relaxation profiling of thermoplastic elastomer filaments used in e-textiles
• Adhesion strength quantification of conductive coatings on PET substrates via 90° peel testing (ASTM D903)
• Quality assurance of medical-grade conductive sutures per ISO 10993-1 biocompatibility-linked mechanical specs
• Educational use in materials science labs for hands-on instruction in stress-strain theory, Hooke’s law validation, and fracture mechanics fundamentals

FAQ
