Hengyi HY-3080TY High-Low Temperature Universal Testing Machine

Overview

The Hengyi HY-3080TY High-Low Temperature Universal Testing Machine is an electromechanical materials testing system engineered for precision mechanical characterization of metallic and ceramic-matrix composite specimens under controlled thermal conditions. Based on the servo-controlled closed-loop load frame architecture, it employs a dual-column龙门 (gantry) structure with high-rigidity crosshead guidance and a digitally synchronized AC servo drive system. The machine integrates seamlessly with independently mounted environmental chambers—capable of operation from –70 °C to +300 °C—to enable quasi-static tensile, compressive, flexural, and shear testing in accordance with standardized thermomechanical protocols. Its core measurement principle relies on calibrated load cell transduction (30 kN nominal capacity), non-contact or extensometer-based strain acquisition, and high-fidelity displacement tracking via precision ball-screw actuation and optical encoder feedback. Designed for laboratory and industrial QC environments, the HY-3080TY delivers traceable force resolution up to 1/500,000 of full scale and maintains ≤0.5 class accuracy across its entire operational range per ISO 7500-1 and ASTM E4.

Key Features

• Gantry-style rigid frame (700 × 420 × 1510 mm) with 210 kg mass and reinforced base for minimal vibration coupling during dynamic loading sequences
• Electromechanical actuation with 0.001–500 mm/min speed control; speed accuracy maintained within ±0.5% of setpoint over full range
• Multi-mode closed-loop control: force, displacement, strain, and stress/strain rate regulation with programmable ramp-hold profiles
• Dual-speed manual jog function and automatic return-to-start capability post-test
• Comprehensive safety architecture including electronic travel limits, overload cutoff (110% FS), real-time diagnostic monitoring of drive voltage/current/load anomalies
• Modular fixture interface supporting ASTM-compliant tensile grips (pneumatic/hydraulic wedge, flat/round specimen), compression platens, 3-/4-point bend fixtures, and interlaminar shear test tooling
• Integrated thermal chamber mounting interface with standardized flange and feedthrough provisions for thermocouple, LVDT, and video extensometry integration

Sample Compatibility & Compliance

The HY-3080TY accommodates metallic specimens—including alloy steels, stainless steels, carbon steels, spring steels, and threaded rods—as well as advanced ceramics and ceramic-matrix composites (CMCs). Specimen dimensions are supported within a 380 mm effective width and 1500 mm vertical stroke envelope, with optional extensions available. All test configurations comply with internationally recognized mechanical testing standards: ASTM E8/E21 (tensile properties of metal at elevated/low temperatures), ISO 6892-1 (metallic materials — tensile testing — part 1: method at room temperature), ISO 15630-1 (reinforcing steels and welded mesh), DIN 50125 (tensile test specimens), JIS Z 2241 (tensile testing of metallic materials), and GB/T 228.1 (Chinese national standard equivalent to ISO 6892-1). When operated under GLP or GMP-regulated workflows, the system supports audit-ready data integrity through timestamped metadata, user access logs, and electronic signature-capable reporting modules aligned with FDA 21 CFR Part 11 requirements.

Software & Data Management

HENGYITEST™ TestControl software provides full instrument orchestration, real-time multi-channel data acquisition (load, displacement, extensometer strain, temperature), and compliant result generation. Users configure test methods via intuitive wizards adhering to standard templates (e.g., ISO 6892-1 Annex A for strain-controlled loading). The software acquires and plots up to four simultaneous curves—including stress–strain, load–displacement, strain–time, and stress–time—with auto-scaling axes, manual zoom/pan, and overlay comparison across multiple specimens. Feature point identification (yield strength Rp0.2, ultimate tensile strength Rm, fracture elongation A5, Young’s modulus E, Poisson’s ratio ν) is performed algorithmically using ASTM E111 and ISO 527-1 methodologies. Raw data exports are available in CSV, XML, and PDF formats with embedded calibration certificates and system configuration snapshots. Audit trails record all parameter modifications, test executions, and report generations with operator ID and UTC timestamps.

Applications

• Tensile property evaluation of structural alloys across service-relevant temperature ranges (e.g., aerospace Ti-6Al-4V at 200 °C, cryogenic stainless steel at –196 °C)
• Mechanical qualification of CMCs for turbine shroud and combustor liner applications per ASTM C1358 and ISO 27385
• Quality conformance testing of reinforcing bars and prestressed concrete tendons to ISO 15630-1 and EN 10080
• Creep and stress-relaxation pre-screening under constant load/strain conditions with thermal hold capability
• Validation of finite element material models using experimentally derived true stress–strain curves
• Interlaminar shear strength (ILSS) determination of fiber-reinforced composites using ±45° rail shear or short-beam shear fixtures

FAQ

What temperature range does the integrated environmental chamber support?
Standard chamber configurations operate from –70 °C to +300 °C; custom variants extend to –100 °C or +1000 °C upon request, subject to chamber model selection and specimen fixturing compatibility.
Is the system compatible with third-party extensometers and thermal imaging systems?
Yes—the HY-3080TY provides analog/digital I/O ports and Ethernet-based API access for synchronization with non-contact video extensometers (e.g., DIC systems), thermographic cameras, and acoustic emission sensors.
Does the software meet FDA 21 CFR Part 11 requirements for electronic records?
HENGYITEST™ TestControl includes role-based user authentication, electronic signatures, immutable audit trails, and data encryption options—fully configurable to satisfy 21 CFR Part 11 and EU Annex 11 validation criteria.
Can the machine perform cyclic fatigue testing?
While primarily optimized for quasi-static tests, the HY-3080TY supports low-cycle fatigue (LCF) protocols up to 5 Hz when equipped with optional high-speed actuation modules and dedicated waveform generators; full high-cycle fatigue (HCF) requires a dedicated servo-hydraulic system.
What calibration documentation is provided with delivery?
Each unit ships with NIST-traceable calibration certificates for load cell, displacement encoder, and strain measurement channels, valid for 12 months under normal operating conditions. On-site verification and recalibration services are available globally via Hengyi-certified engineers.
