Hengyi HY-5080J Universal Tensile Testing Machine

Overview

The Hengyi HY-5080J Universal Tensile Testing Machine is a high-capacity electromechanical testing system engineered for precision mechanical property evaluation of metallic and high-strength non-metallic materials under uniaxial tension, compression, and bending loads. Built on a rigid dual-column frame with reinforced aluminum alloy housing—resistant to aging and discoloration—the system implements a closed-loop servo-controlled drive architecture. A high-torque AC servo motor couples through a precision gearbox to a ground滚珠丝杠 (ball screw) transmission, enabling smooth, low-backlash crosshead movement across an 800 mm stroke. Force measurement relies on a high-stability load cell calibrated to ±0.5% accuracy over a 0.1–100% full-scale range, with digital resolution of 1 part in 250,000. Displacement is tracked via optical encoder feedback with 0.001 mm resolution and ±0.5% linearity. The machine operates within a regulated speed range of 0.001–1000 mm/min, supporting both creep-controlled and strain-rate-dependent protocols required by ISO 6892-1 Annex A (tensile testing at ambient temperature) and ASTM E21 (elevated temperature tensile testing).

Key Features

• High-performance DSP-based control platform delivering real-time data acquisition at ≥1 kHz sampling rate, ensuring dynamic response fidelity during yield point detection and fracture event capture.
• USB 1.1 high-speed interface (12 Mb/s, bulk transfer mode) for deterministic communication between controller and host PC—eliminating latency in closed-loop control loops.
• Four-layer PCB design with optimized signal routing and ground plane segmentation, minimizing electromagnetic interference in industrial laboratory environments.
• Hot-pluggable USB peripherals including extensometers, environmental chambers, and video extensometry modules—configured via software-defined I/O mapping.
• Dual-mode crosshead actuation: fine-positioning (0.001 mm step) for specimen alignment and rapid traverse (up to 1000 mm/min) for pre-load or return cycles.
• Comprehensive hardware safety layer: programmable electronic travel limits, 110% overload cutoff, mechanical emergency stop, and automatic return-to-home upon test completion or fault condition.
• Modular power architecture with 1.5 kW peak output, compatible with standard 3-phase 380 V / 50 Hz supply—no external amplifiers or hydraulic units required.

Sample Compatibility & Compliance

The HY-5080J accommodates standardized tensile specimens per ISO 6892-1 (Type 1A, 2, 5), ASTM E8 (flat and round bars), and GB/T 228.1–2021, with effective test width of 500 mm and maximum gauge length up to 600 mm. Optional wedge-action grips, pneumatic clamps, and high-temperature furnaces (up to 1200 °C) extend applicability to aerospace alloys, nuclear-grade steels, and composite laminates. The system satisfies metrological traceability requirements under ISO/IEC 17025 and supports audit-ready documentation for GLP/GMP-regulated environments. All firmware and calibration certificates comply with GB/T 16491–1996 (Chinese national standard for electronic universal testing machines) and are validated against NIST-traceable reference standards.

Software & Data Management

HYtestV7.0 is a multilingual (9-language) test control and analysis suite built on VB.NET and SQL Server Express. It provides real-time synchronized acquisition of force, displacement, large/small deformation, and time—displayed as live stress–strain, load–extension, or custom parameter plots with auto-scaling axes. The software supports user-defined test methods compliant with ASTM D638, ISO 527, or internal SOPs, including conditional termination (load-, displacement-, or time-triggered), automatic yield point identification (0.2% offset, tangent, or maximum slope), and post-fracture data curation. All raw data are stored in encrypted .mdb format with embedded metadata (operator ID, calibration date, environmental conditions). Audit trail functionality meets FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with Windows domain authentication.

Applications

This system serves as a primary mechanical characterization tool across R&D and QA/QC laboratories in metallurgy, automotive component validation, aerospace fastener certification, nuclear material qualification, and academic materials science research. Typical use cases include determination of ultimate tensile strength (UTS), yield strength (Rp0.2), Young’s modulus (E), percentage elongation (A50mm), reduction of area (Z), and strain hardening exponent (n-value). It further supports cyclic loading protocols (low-cycle fatigue pre-conditioning), creep testing under constant load, and compression testing of cast iron, concrete, and ceramic substrates per ASTM C39 and ISO 7500-1.

FAQ

What standards does the HY-5080J comply with for metal tensile testing?
It fully conforms to GB/T 228.1–2021, ISO 6892-1:2019, ASTM E8/E21, DIN 50125, and JIS Z 2241, with optional add-ons for elevated-temperature and vacuum testing per ASTM E238.
Can the system integrate with third-party extensometers or environmental chambers?
Yes—via standardized USB or analog voltage interfaces; all transducer parameters (gauge length, sensitivity, calibration coefficient) are configurable in HYtestV7.0 without firmware modification.
Is the software validated for regulated pharmaceutical or medical device testing?
When deployed on a validated Windows OS with domain-level access control and enabled audit trail logging, HYtestV7.0 satisfies 21 CFR Part 11 requirements for electronic records in GxP environments.
What maintenance intervals are recommended for long-term accuracy retention?
Biannual load cell recalibration against certified deadweight standards, quarterly lubrication of ball screws with lithium-based grease (NLGI #2), and monthly verification of displacement encoder linearity using laser interferometry traceable to SI units.
Does the machine support automated reporting generation?
Yes—customizable PDF/Excel reports include statistical summaries (mean, SD, CV%), pass/fail flags against specification limits, annotated stress–strain curves, and digital signatures—all exportable with timestamped metadata.
