Hengyi HY-30080PLIN 300 kN Electromechanical Tensile Testing Machine

Overview

The Hengyi HY-30080PLIN is a high-capacity, closed-loop electromechanical tensile testing machine engineered for precision static mechanical property evaluation of metallic and non-metallic materials—including low-carbon steels, structural alloys, composites, polymers, and elastomers. Based on the fundamental principles of uniaxial force-displacement transduction and strain-controlled actuation, the system applies controlled axial loads while synchronously measuring load, displacement, and—when equipped with optional extensometry—true strain. Its 300 kN (≈30.6 ton-force) capacity supports full-scale characterization of construction-grade rebar, welded joints, rolled steel plates, and heavy-section components in accordance with international standard test protocols. The machine complies with core metrological and structural requirements defined in GB/T 16491–1996 (Electronic Universal Testing Machines), GB/T 228.1–2021 (Metallic Materials — Tensile Testing — Part 1: Method of Test at Room Temperature), ISO 6892-1:2019, ASTM E8/E8M, and EN 10002-1, ensuring traceable, auditable, and inter-laboratory comparable results.

Key Features

• High-fidelity dual-range load cell architecture supporting seamless measurement from 0.001% to 100% of full scale (FS), with resolution up to 1/500,000 codes at maximum load—eliminating range-switching artifacts.
• Electromechanical servo drive system delivering precise crosshead velocity control from 0.001 to 500 mm/min, with speed accuracy maintained within ±0.5% of setpoint across the entire range.
• Rigid portal frame (1000 × 680 × 2300 mm) constructed from high-tensile steel with reinforced base plate and guided column assembly, minimizing deflection and ensuring axial alignment stability under peak load.
• Integrated electronic limit protection, overload shutdown (>110% FS), real-time self-diagnostic monitoring of drive current, voltage, and thermal thresholds, and programmable emergency stop logic compliant with IEC 61508 SIL2.
• Modular fixture interface (T-slot table) enabling rapid interchange of standardized夹具 per ISO 23718 and ASTM E1012—tensile grips (pneumatic/hydraulic/wedge-type), compression platens, 3-/4-point bending fixtures, shear adapters, peel & tear clamps, and indentation hardness modules.
• Optional high-precision clip-on or video extensometers (e.g., ISO 9513 Class 0.5 or better) for direct strain measurement during yield plateau, necking, and post-ultimate deformation analysis.

Sample Compatibility & Compliance

The HY-30080PLIN accommodates specimens up to 600 mm wide and 800 mm effective gauge length, with customizable height extension for large-profile samples. It supports standardized specimen geometries per GB/T 228.1, ASTM E8, ISO 6892-1, and JIS Z 2241, including flat sheet, round bar, threaded rod, and notched tensile coupons. All hardware and firmware comply with national and international regulatory frameworks governing mechanical testing infrastructure: GB/T 2611 (General Technical Requirements for Testing Machines), GB/T 12160 (Extensometer Specifications), ISO 7500-1 (Static Calibration of Force Measuring Systems), and ISO 17025:2017 clause 6.4 (Equipment Verification). For GLP/GMP-regulated environments, the system supports audit-trail-enabled operation when paired with validated software (see Software & Data Management section).

Software & Data Management

The machine operates via Hengyi’s proprietary PC-based control and analysis suite, compatible with Windows 10/11 64-bit platforms. The software provides fully scriptable test sequences—including stress-rate, strain-rate, and load-controlled ramp-hold cycles—with real-time visualization of force–displacement, stress–strain, and time-series derivative curves. Raw data export is supported in CSV, XLSX, and universal ASCII formats; metadata tagging includes operator ID, sample ID, environmental conditions (optional sensor integration), calibration certificate reference, and timestamped version history. When configured with 21 CFR Part 11-compliant modules, the system delivers electronic signatures, role-based access control, immutable audit trails, and secure user authentication—meeting FDA, EMA, and MHRA expectations for regulated material qualification workflows.

Applications

• Determination of mechanical parameters per ISO 6892-1 and ASTM E8: ReH (upper yield strength), ReL (lower yield strength), Rp0.2 (0.2% offset yield), Rm (tensile strength), A (elongation at break), Ag (gauge elongation), At (total elongation), and Young’s modulus (E).
• Compression testing of cast iron, concrete cores, and sintered metal parts per GB/T 7314 and ASTM E9.
• Bending characterization of structural beams and weldments using three- and four-point configurations per GB/T 14452 and ASTM D790.
• Cyclic loading studies (low-cycle fatigue pre-screening), creep/relaxation hold tests, and proof-load verification for fasteners and anchor systems.
• Quality assurance in steel mills, rebar fabrication plants, aerospace component suppliers, and third-party certification laboratories performing ISO/IEC 17025-accredited testing.

FAQ

What standards does the HY-30080PLIN comply with for tensile testing of low-carbon steel?
It conforms to GB/T 228.1–2021, ISO 6892-1:2019, ASTM E8/E8M, and EN ISO 6892-1, including all procedural, dimensional, and uncertainty requirements for yield point detection, strain measurement, and result reporting.
