Yuelian YL-S91 Universal Testing Machine for Peel Strength and Mechanical Property Testing

Overview

The Yuelian YL-S91 Universal Testing Machine is an electromechanical force-testing platform engineered for high-reproducibility mechanical characterization of thin-film, laminated, and bonded materials. It operates on the principle of controlled uniaxial displacement under load, employing a stepper motor–driven precision ball screw mechanism to deliver linear motion with minimal energy loss (<15% transmission loss) and stable speed regulation across its full 0.1–500 mm/min range. Designed specifically for peel strength evaluation per ASTM D3330 and GB/T 2792, the system also supports tensile, compression, tear, shear, loop tack, and puncture testing—making it suitable for QC labs, R&D departments, and contract testing facilities handling polymers, elastomers, textiles, paper, leather, composites, and adhesive tapes. Its modular architecture enables rapid fixture interchange via quick-release couplings, while dual-range load cell options (e.g., 50 N / 500 N) allow optimized resolution across low-force peel and higher-force tensile regimes without hardware replacement.

Key Features

• High-resolution force measurement: 1 part in 500,000 full-scale resolution with ±0.30% accuracy—validated against traceable deadweight standards.
• Programmable speed control: Precise digital velocity setting from 0.1 mm/min (for slow-peel adhesion studies) to 500 mm/min (for dynamic tear assessment), with real-time feedback and closed-loop stability.
• Dual-mode operation: Standalone testing via embedded firmware interface or fully integrated PC-based control using USB/RS-232 communication and vendor-supplied software.
• Automated test sequencing: Includes automatic return-to-start, specimen failure detection, upper/lower limit triggering, overload protection, and emergency stop—ensuring operator safety and data integrity.
• Modular fixture compatibility: Quick-change coupling system accommodates standardized grips, peel arms (T-type, 90°, 180°), shear plates, and custom tooling per ISO 2285 or ASTM F963 requirements.
• Energy-efficient drive train: Stepper motor + synchronous timing belt + ground ball screw assembly achieves >85% mechanical transmission efficiency and sub-micron positional repeatability.

Sample Compatibility & Compliance

The YL-S91 is validated for use with specimens ranging from 1 mm-thick rubber sheets to 10 µm-thick pressure-sensitive adhesive films. Its 110 mm test width and 500/800 mm travel accommodate standard peel strips (e.g., 25 mm × 150 mm per ASTM D3330), multi-layer laminates, and flexible packaging substrates. The instrument meets mandatory regulatory alignment for routine quality control in ISO/IEC 17025-accredited laboratories: force calibration traceability to NIM (China National Institute of Metrology), compliance with GB/T 2792–2014 (peel adhesion), ASTM D3330–14 (180° peel), and GB/T 1040.1–2018 (tensile properties). All test reports include timestamped metadata, user ID, environmental conditions (if externally logged), and audit-ready export formats (CSV, PDF, XML) compatible with LIMS integration.

Software & Data Management

The bundled Windows-compatible software provides full test method definition—including multi-step ramp-hold-relax profiles, real-time curve overlay, and automatic peak detection for peel initiation force and plateau adhesion values. Data is stored with full traceability: each record contains raw analog-to-digital samples at ≥1 kHz sampling rate, calibrated force/displacement vectors, operator credentials, and machine serial number. Export functions support GLP-compliant documentation: CSV for statistical analysis in Minitab or JMP, PDF for internal review, and XML for FDA 21 CFR Part 11–aligned electronic records (when deployed with validated user access controls and electronic signatures). Raw data files are immutable; revision history is maintained in encrypted journal logs.

Applications

• Adhesive development: Quantifying peel resistance of PSA tapes, labels, and medical transdermal patches under varying substrate roughness and dwell time.
• Packaging validation: Measuring seal integrity of heat-sealed pouches (ASTM F88), delamination strength of metallized PET/PE laminates, and opening force of easy-tear features.
• Textile & nonwovens: Evaluating bond durability in laminated fabrics, stitch pull-out resistance, and seam strength per ISO 13934-1.
• Automotive interiors: Testing trim adhesion to dashboards, headliner retention force, and foam-to-substrate peel performance under thermal cycling preconditioning.
• Electronics manufacturing: Assessing die-attach shear strength, flex circuit peel adhesion, and conformal coating cohesion via micro-peel fixtures.

FAQ

What peel angles does the YL-S91 support?
The system accommodates 90°, 180°, and T-peel configurations through interchangeable fixture sets—each mechanically aligned to ±0.5° tolerance per ISO 8510-2.
Can the machine perform hold-time tests (creep or stress relaxation)?
Yes—software-defined dwell periods at constant load or displacement are supported, with force decay or strain drift logged at user-selectable intervals (10 ms to 60 s resolution).
Is third-party calibration certification included?
A factory-issued calibration certificate (traceable to NIM) is provided with shipment; annual recalibration services are available through authorized Yuelian service centers in Asia-Pacific regions.
Does the software meet FDA 21 CFR Part 11 requirements?
The software supports Part 11 compliance when configured with role-based access control, electronic signatures, and audit trail activation—subject to site-specific validation by the end user.
What is the maximum sample thickness the standard grips can accommodate?
Standard pneumatic or manual wedge grips accept specimens up to 15 mm thick; optional high-capacity clamps extend this to 30 mm for rigid composites or foams.
