Hengyi HY-3080POLKK,K Universal Tensile Testing Machine (Dual-Column, Floor-Standing, 30 kN Capacity)

Overview

The Hengyi HY-3080POLKK,K is a floor-standing, dual-column electromechanical universal testing machine engineered for high-reproducibility static mechanical characterization of metallic and non-metallic materials under tension, compression, flexure, shear, peel, tear, puncture, and cyclic loading conditions. Designed specifically for demanding industrial and R&D environments—including wire & cable manufacturing, tire cord (steel cord) quality assurance, medical device component validation, and advanced composite development—the system implements closed-loop servo-controlled actuation with real-time load, displacement, and strain feedback. Its modular architecture supports interchangeable load cells (ranging from 1 N to 30 kN), extensometers, and specialized fixtures—enabling traceable, standards-compliant mechanical testing per ISO 527, ASTM D638/D790/D3039, ISO 6892-1, JIS Z2241, GB/T 228.1, and EN 10002-1. The machine operates on the fundamental principle of force transduction via precision strain-gauge-based load cells and high-resolution linear encoders, delivering metrologically sound data for modulus, yield strength, ultimate tensile strength, elongation at break, and stress–strain curve derivation.

Key Features

• Dual-column rigid frame with 700 × 420 × 1600 mm footprint and 210 kg structural mass ensures minimal deflection (<0.02 mm/kN) during high-load testing, critical for accurate modulus determination.
• Full-range load measurement capability from 0.001% to 100% of full scale (FS) without range switching—enabled by 500,000-count A/D resolution and internal/external non-stepped digitization.
• Precisely regulated crosshead speed from 0.001 to 500 mm/min, with ±0.5% speed accuracy across the entire range—essential for creep, relaxation, and rate-dependent property evaluation.
• Integrated electronic limit protection, automatic overload cutoff (110% FS), and real-time diagnostic monitoring of drive current, voltage, and thermal status—meeting IEC 61000-6-2 EMC and functional safety expectations for lab-grade equipment.
• Motorized crosshead with dual-speed (fast/slow) jog control and programmable return-to-start functionality—reducing operator intervention and enhancing throughput in high-volume QC workflows.
• Modular fixture interface compliant with ISO 26203-2 and ASTM E4 standard mounting dimensions—supporting wedge-action grips, pneumatic clamps, bend fixtures, peel test jigs, and custom adapters.

Sample Compatibility & Compliance

The HY-3080POLKK,K accommodates specimens ranging from ultra-fine steel cords (diameter <0.15 mm) and photovoltaic interconnect ribbons to rigid composites, biomedical sutures, elastomeric foams, and laminated packaging films. Its 380 mm effective test width and 800 mm vertical travel enable testing of full-scale automotive gaskets, orthopedic implant components, and multi-layer battery electrodes. All mechanical measurements comply with ISO/IEC 17025 requirements for testing laboratories, and raw data output supports audit-ready documentation per FDA 21 CFR Part 11 (when paired with validated software configuration). The system satisfies mechanical verification criteria outlined in ISO 7500-1 (Class 0.5 accuracy), ASTM E4 (verification of force-measuring systems), and ISO 9513 (extensometer calibration)—with certificate-of-conformance documentation available upon request.

Software & Data Management

HYtestV7.0 is a multilingual (nine-language) PC-based test control and analysis platform built on VB.NET and SQL Server architecture. It provides real-time synchronized acquisition of load, displacement, and optional strain signals at up to 1 kHz sampling rate. The software features automated pass/fail decision logic based on user-defined criteria (e.g., fracture detection via slope threshold, load drop >15%, or time-based termination), dynamic axis scaling, parameter point extraction (yield point, elastic modulus, offset yield, breaking elongation), and customizable report generation in PDF/XLS formats. All test methods are stored as XML-configurable templates—allowing rapid reconfiguration for ASTM D882 (thin films), ISO 1184 (textiles), or proprietary OEM protocols. Audit trails record operator ID, timestamp, method version, calibration status, and raw data hash—ensuring GLP/GMP traceability and alignment with ISO 13485 and ICH Q5E regulatory expectations.

Applications

• Steel cord and bead wire tensile strength, modulus, and necking behavior for radial tire manufacturing (per ISO 6892-1 Annex B and ASTM A1061).
• Mechanical validation of lithium-ion battery current collectors (Cu/Al foil tensile properties, weld bond integrity).
• Peel strength and adhesion performance of medical pressure-sensitive adhesives (PSAs) per ISO 29862 and ASTM D3330.
• Cyclic fatigue testing of cardiovascular stents and orthopedic fixation devices under ISO 14801 and ASTM F2129 protocols.
• Compression testing of thermal insulation materials (aerogels, phenolic foams) per ASTM C165 and ISO 844.
• Three- and four-point bending of fiber-reinforced polymer (FRP) laminates for aerospace secondary structures (ASTM D7264).
• Quality control of extruded polymer profiles, injection-molded housings, and elastomeric seals in automotive Tier-1 supply chains.

FAQ

What standards does the HY-3080POLKK,K support for steel cord testing?
It complies with ISO 6892-1 (tensile testing of metallic materials), ASTM A1061 (steel tire cord), and GB/T 28289 (Chinese national standard for steel cord mechanical properties), including requirements for gauge length, strain rate control, and extensometer use.
Can the system perform controlled-strain-rate tests required by ISO 6892-1 Annex A?
Yes—its closed-loop strain control mode supports rates from 0.002% to 6% FS/s, with accuracy better than ±0.5% of set value above 0.05% FS/s, satisfying Annex A’s quasi-static testing conditions.
Is the software 21 CFR Part 11 compliant out of the box?
HYtestV7.0 includes role-based access control, electronic signatures, and immutable audit trails; however, full Part 11 compliance requires site-specific validation documentation and IT infrastructure alignment (e.g., secure network, backup policy, user training records).
What is the maximum specimen thickness that can be accommodated between grips?
With standard wedge grips, the maximum parallel jaw thickness is 25 mm; custom thick-section grips (up to 50 mm) are available upon request.
Does the machine support high-temperature testing?
The base system is rated for ambient operation (10–35°C, ≤80% RH); integration with environmental chambers (−70°C to +300°C) is supported via third-party chamber interfaces and calibrated thermal compensation routines.
