Hengyi HY-0580LTVED Membrane Adhesion Strength Tester – Single- or Dual-Arm Electronic Universal Testing Machine

Overview

The Hengyi HY-0580LTVED Membrane Adhesion Strength Tester is a precision-engineered electronic universal testing machine designed for quantitative mechanical characterization of thin-film adhesion interfaces, including peel, shear, and tensile debonding behaviors. Built on a rigid single- or dual-arm structural platform, it operates on the principle of controlled displacement or force actuation via a servo-motor-driven crosshead, enabling high-fidelity acquisition of load–displacement, stress–strain, and time-dependent mechanical response data. Its architecture conforms to fundamental metrological requirements for static uniaxial testing as defined in ISO 7500-1, ASTM E4, and GB/T 16852.1—ensuring traceable force measurement, repeatable motion control, and thermally stable mechanical alignment. The system is purpose-built for evaluating interfacial integrity in functional membranes used across medical device coatings, flexible electronics encapsulation, battery separator laminates, pharmaceutical transdermal patches, and optical film stacks—where sub-newton-level resolution and micro-displacement fidelity are critical.

Key Features

• Modular load cell configuration supporting interchangeable sensors from 1 N to 5000 N, all calibrated to ≤0.5 accuracy class per ISO 376 and GB/T 16491.
• High-resolution force measurement system with ±500,000-count A/D conversion, maintaining constant resolution across the full dynamic range without internal range switching.
• Precise speed control from 0.001 to 500 mm/min, with closed-loop feedback ensuring ±0.5% speed accuracy per ISO 5893 and GB/T 228.1.
• Dual-mode control architecture: stress-controlled ramping (0.005–6% FS/S) and strain-controlled ramping (0.002–6% FS/S), each with rate-dependent accuracy specifications aligned with ASTM D882 and ISO 527-1.
• Integrated safety subsystems including electronic travel limits, overload cutoff (>110% FS), automatic return-to-start, programmable end-of-test triggers (force-, displacement-, or time-based), and real-time diagnostic monitoring of drive voltage, current, and thermal load.
• Robust mechanical frame with reinforced aluminum alloy uprights and preloaded ball-screw transmission, minimizing compliance and ensuring long-term dimensional stability under cyclic loading.

Sample Compatibility & Compliance

The HY-0580LTVED accommodates standardized and custom specimen geometries—including ASTM D903 peel strips, ISO 8510-1 T-peel configurations, GB/T 3923 textile specimens, and GB/T 1040 plastic dumbbells—via interchangeable grips and fixtures (e.g., pneumatic clamps, roller peel jigs, bend supports). It meets essential regulatory and quality framework requirements: GB/T 2611 (General Technical Requirements for Testing Machines), GB/T 16491 (Electronic Universal Testing Machines), and ISO 7500-1 (Static Calibration of Force-Measuring Systems). When paired with validated software and documented calibration records, the system supports GLP-compliant test execution and satisfies audit readiness criteria for ISO/IEC 17025 laboratories. Optional documentation packages include uncertainty budgets per GUM (JCGM 100) and traceable calibration certificates accredited to CNAS standards.

Software & Data Management

The embedded control and analysis software provides ISO/IEC 17025-aligned test sequencing, real-time curve overlay, multi-channel synchronized data logging (load, displacement, extensometer strain), and automated report generation compliant with FDA 21 CFR Part 11 (when configured with electronic signature modules and audit-trail logging). Users may define custom test protocols—including multi-step ramp-hold-relax cycles, creep/stress relaxation sequences, and cyclic fatigue profiles—with parameter validation against predefined tolerances. Raw data exports to CSV, Excel, and XML formats; processed results include modulus, yield point, ultimate strength, elongation at break, and adhesion energy (J/m²) calculated per ASTM D1876 (T-peel) or ISO 8510-2 (90° peel). Software updates are version-controlled and distributed with release notes referencing applicable standards revisions.

Applications

• Quantification of adhesive bond strength between polymer films and substrates in flexible packaging and barrier laminate development.
• Interfacial shear resistance testing of PVD/CVD-coated membranes in MEMS and sensor fabrication.
• Peel performance evaluation of pressure-sensitive adhesives (PSAs) used in wearable medical electrodes and drug delivery patches.
• Mechanical reliability assessment of anode/cathode separator interfaces in lithium-ion battery pouch cells.
• Quality control of ultrathin metallized PET films subjected to thermoforming or lamination processes.
• Research-grade characterization of bioresorbable polymer membranes under hydrated or accelerated aging conditions.

FAQ

What standards does the HY-0580LTVED support out of the box?
It natively supports GB/T 16491, GB/T 2611, ISO 7500-1, ASTM E4, and ASTM D903. Additional standards (e.g., ISO 11339, JIS K6850) can be implemented via custom test method templates.
Can the system perform creep or stress relaxation tests?
Yes—using the strain- or stress-controlled hold modes with user-defined duration and tolerance bands, fully compliant with ASTM D2990 and ISO 899-1.
Is third-party calibration and certification available?
Hengyi provides factory calibration with traceable certificates; optional CNAS-accredited field calibration and ISO/IEC 17025 validation services are available upon request.
What is the minimum resolvable force for the 1 N load cell?
With ±500,000-count resolution and 0.5% accuracy class, the effective resolution is ≤2 µN, suitable for ultra-thin membrane and nanolayer adhesion studies.
Does the software support automated pass/fail decision logic based on specification limits?
Yes—users can configure acceptance criteria per test step, with visual alerts, data flagging, and exportable compliance summaries.
