Hengyi HY-035022 Electronic Universal Testing Machine

Overview

The Hengyi HY-035022 Electronic Universal Testing Machine is a precision-engineered electromechanical system designed for static mechanical property characterization of materials under uniaxial tensile, compressive, flexural, shear, peel, and tear loading conditions. It operates on the principle of closed-loop servo control, integrating high-resolution force transduction, displacement feedback via precision ball screw actuation, and real-time strain acquisition through extensometry or crosshead displacement correlation. With a maximum load capacity of 3000 N and a certified accuracy class of 0.5 per ISO 7500-1 and ASTM E4, the system delivers traceable, reproducible results across a broad spectrum of material classes—including thin metallic foils, polymer films, elastomeric sheets, fiber-reinforced composites, biomedical sutures, and micro-electromechanical components. Its wide speed range (0.001–500 mm/min), ultra-fine force resolution (±500,000 counts full-scale), and dual-mode control architecture (force, displacement, and strain) enable compliance with dynamic test protocols such as low-cycle fatigue and controlled-rate stress relaxation—making it suitable for both R&D validation and routine QC verification in regulated environments.

Key Features

• Triple-closed-loop control system supporting simultaneous force, displacement, and strain regulation for high-fidelity test execution and repeatability.
• Precision ground ball-screw-driven crosshead with dual-speed manual/automatic positioning and electronic end-limit protection to prevent mechanical overtravel.
• Auto-diagnostic subsystem continuously monitors drive voltage, current, thermal load, and sensor integrity; triggers immediate safety shutdown upon detection of overpressure, overcurrent, or signal anomaly.
• Modular fixture interface accommodating standardized grips (pneumatic, wedge, vise), bending fixtures (3-point/4-point), peel fixtures (T-peel, 90° peel), and custom-designed tooling per ASTM D638, ISO 527, ISO 178, ASTM D1876, and GB/T 2567.
• Full-range force measurement without range switching—maintaining constant resolution (0.0002% FS) from 0.1% to 99.99% of 3000 N capacity.
• Integrated safety logic including programmable stop conditions: preset time, target load, defined deformation, or automatic fracture detection based on slope discontinuity in force-displacement curves.

Sample Compatibility & Compliance

The HY-035022 accommodates specimens up to 120 mm wide and 500 mm tall, enabling testing of miniature coupons, thin films (≥10 µm thickness), micro-wires, adhesively bonded joints, and layered laminates. Its mechanical design conforms to ISO 2041 (testing machine terminology), ISO 7500-1 (static calibration), and ASTM E4 (verification of force-measuring systems). Software-configurable test methods support full alignment with GB/T 228.1, ISO 6892-1, ASTM D638, ASTM D790, ISO 178, JIS K7113, and DIN 53455. The system supports audit-ready data capture required for GLP-compliant laboratories and satisfies foundational requirements for FDA 21 CFR Part 11 when deployed with validated software configurations and user access controls.

Software & Data Management

Control and analysis are performed via Hengyi’s proprietary Windows-based software suite, built on VB.NET and SQL Server Compact Engine for deterministic I/O handling and relational data integrity. Real-time plotting features include auto-scaling axes, multi-curve overlay, parameter point marking (yield onset, elastic modulus, break point), and interactive zoom/pan functionality. All raw data—including time-stamped force, displacement, and strain arrays—are stored in encrypted binary + CSV dual format with metadata tagging (operator ID, sample ID, environmental conditions, calibration timestamp). Custom method templates can be created, versioned, and exported for inter-laboratory harmonization. Export modules support direct integration with LIMS platforms via ODBC and generate PDF reports compliant with ISO/IEC 17025 documentation standards.

Applications

• Quality assurance of medical device components (e.g., suture tensile strength per ISO 10993-12, catheter shaft stiffness).
• Mechanical validation of packaging films (peel strength per ASTM F904, seal integrity per ASTM F88).
• Research-grade characterization of nanocomposites and hydrogels under small-strain regimes.
• Educational use in university materials science labs for stress–strain curve derivation and modulus calculation.
• Supplier qualification testing for automotive gaskets, battery separator membranes, and flexible printed circuit substrates.
• Regulatory submission support for CE-marked products requiring mechanical performance dossiers per MDR Annex I.

FAQ

What international standards does the HY-035022 comply with for force calibration?
It meets ISO 7500-1 Class 0.5 requirements and is verifiable per ASTM E4 using certified reference load cells traceable to NIST or NMIs.
Can the system perform cyclic loading tests?
Yes—the triple-closed-loop architecture enables programmed low-cycle fatigue tests with user-defined waveforms (sine, triangle, trapezoidal), dwell periods, and reversal criteria.
Is the software compatible with networked lab environments?
The software supports domain-authenticated login, role-based permissions, and centralized database deployment on Windows Server for multi-user concurrent access.
What is the minimum measurable force at full resolution?
At 3000 N full scale and ±500,000-count resolution, the theoretical minimum discernible increment is 0.006 N—enabling sub-mN-level sensitivity for ultra-thin specimen testing.
Does the system support third-party extensometers?
Yes—standard analog (±10 V) and digital (LVDT, video-based) extensometer inputs are provided, with configurable gain and offset compensation in software.
