Overview
The Hengyi HY-3080ERTT is a dual-column, electromechanical universal testing machine engineered for precision mechanical characterization of materials across research, quality assurance, and production environments. Built on a rigid, low-deflection龙门-style frame, it employs servo-controlled actuation and high-precision preloaded ball screws to deliver repeatable force application and displacement tracking under static and quasi-static loading conditions. The system operates on the fundamental principle of controlled uniaxial tension, compression, bending, peel, shear, and cyclic loading—enabling quantification of tensile strength, yield stress, Young’s modulus, elongation at break, Poisson’s ratio, creep compliance, and stress relaxation behavior. Its modular architecture supports interchangeable load cells ranging from 1 N to 30 kN, allowing seamless adaptation from micro-scale polymer films to macro-scale composite laminates or metallic fasteners—without hardware recalibration.
Key Features
- Rigid dual-column steel frame with optimized stiffness-to-mass ratio, minimizing parasitic deflection during high-load testing.
- Brushless AC servo motor and digital drive system delivering smooth, low-noise motion and consistent torque output across the full speed range (0.001–1000 mm/min).
- Two precision-ground, pre-tensioned ball screws ensuring axial alignment stability and eliminating backlash during bidirectional operation.
- High-accuracy, bidirectional load cell (ISO 7500-1 Class 0.5 compliant) with internal temperature compensation and ≥500,000-count resolution—no range switching required.
- Digital controller supporting open-loop and closed-loop modes, with configurable PID tuning for force, displacement, or strain control.
- Integrated safety architecture: electronic end-limit detection, software-enforced overload cutoff (>110% FS), real-time diagnostic monitoring of drive voltage/current/temperature, and emergency stop circuitry meeting IEC 61800-5-2 requirements.
- Motorized crosshead with dual-speed (fast/slow) jog control and programmable auto-return functionality—reducing operator intervention and cycle time variability.
Sample Compatibility & Compliance
The HY-3080ERTT accommodates a broad spectrum of specimen geometries and mechanical behaviors—including thin films (e.g., PET, PVDF), elastomeric strips (natural rubber, silicone), fine wires (<0.1 mm diameter), biomedical sutures, orthopedic fixation devices, photovoltaic interconnect ribbons, pharmaceutical blister lidding, and fiber-reinforced thermoplastics. Its 380 mm test width and 800 mm vertical travel support standardized specimens per ASTM D638, ISO 527, ASTM D882, ISO 1184, ASTM D1876 (T-peel), and ISO 11339 (adhesion). The system meets mechanical safety requirements per ISO 12100 and electrical safety per IEC 61000-6-2/6-4. Optional accessories—including pneumatic grips, environmental chambers (-70°C to +300°C), extensometers (contact and non-contact), and video extensometry modules—enable expansion into GLP/GMP-regulated workflows and ASTM E8/E21 high-temperature metal testing protocols.
Software & Data Management
Bundled with HengyiTest v5.2 software, the HY-3080ERTT provides a Windows-based interface for test method definition, real-time curve visualization (force–displacement, stress–strain, creep master curves), and post-test analysis. All raw data—including timestamped load, position, and deformation channels—are stored in SQL Server-compatible binary format with embedded metadata (operator ID, sample ID, environmental conditions, calibration traceability). Audit trails record user actions, parameter changes, and system events—supporting compliance with FDA 21 CFR Part 11 when configured with electronic signatures and role-based access control. Export options include CSV, PDF reports (with customizable templates), and image-captured curve overlays. Custom test methods can be scripted using VB.NET-based logic modules, enabling automated multi-step protocols (e.g., preconditioning → ramp → hold → recovery) without third-party coding.
Applications
- Quality control of packaging films (tensile strength, puncture resistance, seal integrity) per ASTM F88/F1921.
- Mechanical validation of medical devices: suture tensile strength (ISO 10993-12), catheter kink resistance (ISO 80369), and implant anchorage testing.
- Characterization of photovoltaic interconnection materials—solder bond shear strength, ribbon tensile ductility, and thermal cycling-induced fatigue.
- Research-grade polymer rheomechanics: viscoelastic modeling via dynamic load-unload cycles and time–temperature superposition.
- Automotive component verification: gasket compression set (ASTM D395), hose burst pressure precursors, and fastener torque–tension correlation.
- Educational laboratories: hands-on instruction in material science fundamentals, including Hooke’s law verification, necking onset detection, and fracture energy estimation.
FAQ
What load cell options are available for the HY-3080ERTT, and how are they calibrated?
The system supports up to three user-swappable load cells (1 N, 500 N, and 30 kN standard configurations), each factory-calibrated per ISO 376 Annex B and supplied with NIST-traceable certificates. Calibration coefficients are stored internally and auto-loaded upon cell recognition.
Does the controller support closed-loop strain control using an external extensometer?
Yes—the digital controller accepts analog inputs from LVDT, clip-on, or video extensometers and executes real-time strain feedback loops with user-defined PID parameters and rate limits.
Can test data be exported to LIMS or ERP systems?
Raw data files (.hdt) and summary reports (.csv/.pdf) are accessible via UNC path or network share; API integration (RESTful endpoints) is available under extended support contracts.
Is the system compatible with ISO/IEC 17025-accredited laboratories?
When operated with documented procedures, scheduled verification (per ISO 17025 Clause 6.4.10), and annual third-party metrological audit, the HY-3080ERTT satisfies technical competence requirements for mechanical testing scope accreditation.
What maintenance intervals are recommended for long-term accuracy retention?
Ball screw lubrication every 2,000 operational hours; load cell zero-check and system verification before each shift; full mechanical inspection and calibration every 12 months—or after any impact event exceeding 150% of maximum rated load.
