Overview
The Hengyi HY-0580 is a high-precision, dual-column portal-style universal testing machine engineered specifically for mechanical characterization of fine-diameter elastic fibers—particularly spandex (elastane) yarns used in warp-knitted fabrics. It operates on the fundamental principle of electromechanical force-displacement transduction, utilizing closed-loop servo control to apply precisely regulated tensile, compressive, or flexural loads while simultaneously capturing high-fidelity load, displacement, and strain data. Designed for compliance with static mechanical testing standards—including ASTM D2256 (tensile properties of textile yarns), ISO 20795-1 (mechanical testing of dental polymers), and GB/T 1040.1 (plastics tensile testing)—the system delivers traceable, repeatable results essential for R&D validation, QC release testing, and regulatory documentation in textile, medical device, and advanced polymer manufacturing environments.
Key Features
- Robust dual-column steel frame with preloaded high-precision ball screws (imported) ensures minimal deflection and long-term dimensional stability under cyclic loading.
- High-torque, maintenance-free Panasonic AC servo motor and drive system enables smooth, low-noise operation across the full speed range (0.001–500 mm/min) with ±0.5% speed accuracy.
- Calibrated bidirectional load cell (single or multi-cell configuration available) offers resolution up to ±500,000 digital counts over full scale, with no internal range switching—preserving linearity and repeatability from 0.1% to 100% FS.
- Digital controller supports real-time stress, strain, and displacement control modes, compliant with ISO 5893 and ASTM E4 requirements for closed-loop feedback fidelity.
- Integrated safety architecture includes electronic travel limits, overload cutoff (triggered at ≥110% of selected capacity), automatic return-to-start, and programmable stop conditions (time-, load-, or deformation-based).
- Intuitive handheld remote control and multilingual (English, Chinese, Spanish, German) GUI facilitate rapid setup and operator independence across global production sites.
Sample Compatibility & Compliance
The HY-0580 accommodates a broad spectrum of low-force, high-elongation specimens typical in functional textiles and biomedical materials: spandex filaments (10–500 dtex), elastomeric monofilaments, braided suture threads, thin metallic ribbons (e.g., NiTi shape-memory wires), PVDF piezoelectric films, hydrogel sheets, and silicone tubing. Its 380 mm test width and 800 mm vertical stroke allow testing of knitted fabric swatches, looped yarn configurations, and multi-strand bundles without modification. All hardware and firmware are designed to support GLP/GMP-aligned workflows: audit trails, user access levels, electronic signatures (via optional software module), and 21 CFR Part 11-compliant data integrity features can be implemented when paired with certified PC-based acquisition software.
Software & Data Management
The system interfaces with Hengyi’s proprietary MTestWin software (Windows OS), which provides ISO 17025-aligned test method templates, automated report generation (PDF/Excel), raw-data export (CSV), and customizable pass/fail criteria per specimen batch. Data logging occurs at ≥100 Hz sampling rate, preserving transient events during yield or necking. Calibration certificates—including traceability to CNAS-accredited metrology labs in Shanghai—are supplied with each unit. Optional integration with LIMS platforms (via OPC UA or TCP/IP) enables direct data ingestion into enterprise quality management systems (QMS) for statistical process control (SPC) and CAPA tracking.
Applications
- Tensile strength, elongation-at-break, and modulus determination of spandex yarns per ASTM D2256 and ISO 20795-1 Annex C.
- Creep and stress-relaxation profiling of thermoplastic elastomers under controlled temperature-humidity conditions (when integrated with environmental chamber).
- Mechanical validation of medical-grade elastic components: catheter shafts, wound closure strips, and orthodontic elastics.
- Compression testing of soft foams and hydrogels per ISO 13314.
- Peel adhesion assessment of pressure-sensitive tapes and laminated packaging films (using 90°/180° peel fixtures).
- Three- and four-point bending of thin composite laminates and flexible PCB substrates.
FAQ
What spandex yarn linear densities is the HY-0580 optimized for?
The system is calibrated for filaments ranging from 20 dtex to 1200 dtex, with standard grips accommodating diameters from 15 µm to 300 µm. Custom micro-grips and pneumatic clamping options are available for sub-10 µm monofilaments.
Can the machine perform cyclic fatigue testing on elastic fibers?
Yes—when configured with the optional high-cycle controller and real-time strain feedback (via extensometer), it supports up to 10⁶ cycles at frequencies ≤5 Hz, meeting ASTM D4392 for dynamic fatigue evaluation.
Is third-party calibration and certification included?
Each unit ships with a factory calibration certificate traceable to CNAS (China National Accreditation Service). Optional on-site verification by TÜV SÜD or SGS is available upon request.
How is data integrity ensured for regulated industries?
With the MTestWin Advanced Edition, users gain 21 CFR Part 11 compliance: role-based access control, electronic signatures, immutable audit logs, and encrypted database storage—all validated per IQ/OQ protocols.
What environmental conditions are recommended for optimal performance?
Operational ambient: 10–35 °C, RH ≤80% non-condensing. For ISO 554-standard textile testing, integration with a climate-controlled chamber (20 ±2 °C / 65 ±4% RH) is strongly advised.
