Hengyi HY-3080TYU Dual-Column Electromechanical Tensile Testing Machine

Overview

The Hengyi HY-3080TYU is a dual-column, electromechanical universal testing machine engineered for high-precision static mechanical characterization of metallic and non-metallic materials under uniaxial tension, compression, bending, shear, peel, tear, and puncture loading conditions. Designed around a rigid portal frame architecture with precision-ground ball screws and servo-controlled AC motor actuation, the system delivers stable force application and repeatable displacement control across its full 30 kN capacity. Its measurement principle relies on closed-loop feedback control of load (via calibrated S-type or inline load cells), displacement (via high-resolution optical encoder), and optional strain (via extensometer or video-based digital image correlation). The machine complies with fundamental mechanical test standards including ISO 6892-1 (metal tensile), ASTM E8/E21 (tensile properties of metals), ASTM D638/D790 (plastics), ISO 527 (polymer tensile), and ISO 179 (impact-modified plastics), enabling traceable, auditable results suitable for GLP, GMP, and ISO/IEC 17025 environments.

Key Features

• Rigid龙门-style (portal) structural design with 210 kg reinforced steel frame, minimizing deflection and ensuring long-term mechanical stability.
• High-resolution force measurement system with ±0.5% accuracy over 0.001–100% full scale, supported by internal 500,000-count A/D conversion without range switching.
• Displacement resolution of 0.001 mm and accuracy of ±0.5% of reading, enabled by linear optical encoder coupled to precision ball screw drive.
• Wide speed range: 0.001–500 mm/min, continuously adjustable with ±0.5% speed accuracy — suitable for quasi-static creep, relaxation, and high-rate deformation studies.
• Integrated safety architecture including electronic limit switches, overload protection (110% FS cutoff), real-time self-diagnostic routines for drive, load cell, and encoder subsystems.
• Motorized crosshead with dual-speed (fast/slow) jog control and programmable auto-return functionality post-test.
• Modular load cell support: interchangeable sensors from 1 N to 30 kN, allowing calibration traceability to national metrology institutes (e.g., NIM, NIST).

Sample Compatibility & Compliance

The HY-3080TYU accommodates a broad spectrum of specimen geometries and material classes: high-strength steel wires (diameters ≥0.1 mm), copper/aluminum foils, photovoltaic interconnect ribbons, polymer films (<100 µm), medical tubing, suture materials, orthopedic implants, composite laminates, elastomeric seals, and fiber-reinforced textiles. Fixturing options include pneumatic wedge grips, hydraulic vise clamps, bend fixtures (3- and 4-point), peel test jigs, and custom-designed holders for irregular components. All test methods are fully compliant with ASTM D3039 (composite tensile), ISO 12947 (abrasion resistance), JIS Z 1522 (packaging tape peel), YY/T 0681 (medical packaging), and QC/T 263 (automotive fasteners). Data acquisition meets FDA 21 CFR Part 11 requirements when used with audit-trail-enabled software configurations.

Software & Data Management

HYtest V7.0 is a multilingual (9-language) Windows-based test control and analysis platform built on VB.NET and SQL Server Compact. It supports real-time synchronized acquisition of force, displacement, large/small deformation, and time-stamped events. The software enables automated test sequencing, conditional stopping (load-, displacement-, time-, or fracture-triggered), dynamic curve scaling, and parameter extraction (yield strength, Young’s modulus, elongation at break, secant modulus, fracture energy). All raw data are stored in encrypted binary + CSV dual format with embedded metadata (operator ID, calibration certificate ID, environmental conditions). Audit trails record every user action—including method edits, result deletions, and calibration updates—with timestamp and digital signature. Export modules support PDF report generation, Excel-compatible output, and direct integration with LIMS via ODBC.

Applications

This system serves as a core mechanical characterization tool across regulated and research-intensive sectors. In wire & cable manufacturing, it validates tensile strength and elongation of stainless steel, galvanized, and alloyed steel conductors per IEC 61000-4-5 and GB/T 228.1. In medical device R&D, it quantifies pull-out strength of suture anchors, burst pressure of catheter shafts, and tensile integrity of hydrogel wound dressings per ISO 10993-12. For photovoltaic module qualification, it measures ribbon solder joint strength and backsheet peel adhesion under thermal cycling preconditioning. In academia, it supports constitutive modeling of viscoelastic polymers, fatigue life prediction of elastomeric mounts, and interfacial shear strength evaluation in metal-matrix composites. Quality labs use it for incoming inspection of fasteners, spring rate verification, and shelf-life compression testing of foam packaging.

FAQ

What standards does the HY-3080TYU support out-of-the-box?
Preconfigured test methods cover ASTM E8, D638, D790, D1709, ISO 6892-1, 527-1, 179-1, JIS K 7113, and GB/T 228.1 — all editable and extendable via the HYtest V7.0 method editor.
Can the system perform cyclic or fatigue testing?
Yes — with optional waveform generator module, it executes sinusoidal, triangular, trapezoidal, and user-defined load/displacement waveforms up to 5 Hz, supporting low-cycle fatigue (LCF) and stiffness degradation monitoring.
Is third-party calibration certification included?
Factory calibration is performed using NIST-traceable deadweight standards; optional UKAS-accredited calibration certificates (ISO/IEC 17025) are available upon request.
How is data integrity ensured for regulatory submissions?
HYtest V7.0 supports 21 CFR Part 11 compliance through role-based access control, electronic signatures, immutable audit logs, and secure database encryption — configurable per site validation protocols.
What maintenance is required for long-term accuracy?
Annual recalibration of load cell and encoder is recommended; routine checks include lubrication of ball screws, verification of grip alignment, and validation of emergency stop function — all documented in the included maintenance logbook.
