Yuelian YL-S711 Digital Tensile Testing Machine for Adhesive Tape Peel Strength Measurement

Overview

The Yuelian YL-S711 Digital Tensile Testing Machine is an electromechanical universal testing system engineered for precision measurement of peel strength, adhesion force, release force, tensile strength, and related mechanical properties of pressure-sensitive adhesive (PSA) tapes, release liners, films, and thin flexible materials. It operates on the principle of controlled uniaxial force application via servo-motor-driven crosshead displacement, with real-time acquisition of load and displacement data using high-fidelity analog-to-digital conversion (ADC) architecture. The system complies with standardized test methodologies defined in ASTM D3330, ASTM D903, ISO 8510-2, PSTC-101, and GB/T 2792—enabling traceable, repeatable, and auditable measurements required for quality control, R&D validation, and regulatory documentation in adhesive manufacturing, packaging, medical device, and electronics assembly industries.

Key Features

• Precision servo motor drive coupled with ground ball screw transmission ensures low mechanical backlash, high positional repeatability, and minimal maintenance over extended operational cycles.
• Dual high-resolution ADC modules deliver simultaneous 1/500,000 full-scale resolution for both load (±0.5% accuracy) and displacement (0.01 mm resolution), eliminating range-switching artifacts common in stepped amplifier architectures.
• Modular fixture interface supports interchangeable grips—including 180° peel, 90° peel, loop tack, and tensile jaw configurations—for standardized evaluation across multiple test modes per ISO 2922 and ASTM D6252.
• Full PC-based control software enables programmable test profiles: constant-rate, constant-load, displacement-limited, or multi-stage ramp-hold sequences—with automatic stop triggers upon specimen rupture, overload, or user-defined force/displacement thresholds.
• Robust mechanical construction features CNC-machined 45# tool steel crossbeam, cold-rolled steel base plate (2.0 mm thickness), and electrostatically coated dust shield—designed for long-term dimensional stability under laboratory environmental fluctuations.
• USB 2.0 opto-isolated communication interface prevents ground-loop interference and supports hot-plug operation—ensuring compatibility with modern Windows OS platforms (Windows 7 through Windows 11) without driver conflicts or serial port damage risk.

Sample Compatibility & Compliance

The YL-S711 accommodates specimens up to 140 mm wide and 500 mm effective travel length, making it suitable for standard PSA tape widths (e.g., 25 mm, 50 mm, 75 mm strips) as well as laminated substrates and flexible packaging composites. Its force capacity (up to 5 kN) covers routine peel tests (typically 0.1–50 N) and higher-load applications such as liner release from silicone-coated PET or heavy-duty double-sided tapes. All test protocols adhere to internationally recognized standards including ASTM D3330 (180° peel), ASTM D903 (T-peel), ISO 8510-2 (peel adhesion), and GB/T 2792 (Chinese national standard for peel strength). The system supports GLP-compliant data integrity through audit-trail-enabled software permissions (operator, supervisor, administrator tiers), timestamped raw data logging, and export-ready reports compliant with FDA 21 CFR Part 11 requirements when configured with electronic signature modules.

Software & Data Management

The embedded Windows-native software provides comprehensive test automation and post-processing functionality. Users can define multi-interval analysis windows to extract average peel force over specified displacement ranges (e.g., steady-state region excluding initial transient), calculate standard deviations, and generate comparative overlays of up to 12 curves with independent scaling and color coding. Data output includes tabular summaries (maximum force, average peel force, minimum peel force, peel strength in N/mm or N/25mm), stress–strain derivatives (modulus, elongation at break), and graphical representations (force vs. displacement, normalized peel energy plots). Reports are exportable in PDF, Word (.docx), and Excel (.xlsx) formats, with bilingual UI support (English/Chinese) and dynamic unit translation across SI, metric, and imperial systems—including N·mm·MPa, lbf·in·kpsi, and gf·cm·kgf/cm² conventions. Raw binary data files (.dat) preserve full-resolution sensor traces for third-party statistical analysis or metrological reprocessing.

Applications

• Quantification of peel adhesion performance of acrylic, rubber-based, and silicone PSAs on PET, PP, PE, and paper substrates.
• Evaluation of release liner debonding characteristics—critical for medical transdermal patches, label stocks, and protective films.
• Quality assurance of film-to-film laminates used in flexible electronics encapsulation and battery separator production.
• Validation of aging effects (thermal, UV, humidity) on adhesive bond integrity per ASTM D1876 (T-peel) or ISO 11339.
• Comparative benchmarking of competitive adhesive formulations during new product development cycles.
• Supporting ISO/IEC 17025-accredited laboratory testing where documented uncertainty budgets and calibration traceability (to NIST or CNAS-certified standards) are mandatory.

FAQ

What standards does the YL-S711 comply with for peel strength testing?
The system supports test methods aligned with ASTM D3330, ASTM D903, ISO 8510-2, PSTC-101, and GB/T 2792—covering 90°, 180°, and T-peel configurations.
Can the machine perform both peel and tensile tests on the same platform?
Yes—the modular grip system and programmable test profiles allow seamless switching between peel, tensile, compression, bend, tear, and shear modes without hardware modification.
Is raw data export supported for external statistical analysis?
Yes—full-resolution .dat files containing time-stamped load and displacement values are retained locally and exportable for advanced analysis in MATLAB, Python, or Minitab.
Does the software meet FDA 21 CFR Part 11 requirements?
When deployed with role-based user authentication, electronic signatures, and audit-trail logging enabled, the software satisfies core Part 11 criteria for electronic records and signatures in regulated environments.
What is the recommended calibration frequency for ISO/IEC 17025 compliance?
Annual calibration against traceable reference standards is advised; interim verification using certified check weights and displacement gauges should be performed daily or per-shift per laboratory SOPs.
