YL-S90 Electronic Tensile Testing Machine with Drum Peel Fixture

Overview

The YL-S90 Electronic Tensile Testing Machine is a precision-engineered instrument designed for quantitative mechanical evaluation of adhesion, cohesion, and structural integrity in flexible laminates, coated substrates, and bonded assemblies. Specifically configured with a drum peel fixture, it implements standardized angular peel geometry per ASTM D3330 and GB/T 2792 to deliver repeatable, traceable measurements of peel strength—critical for quality assurance in packaging, medical device manufacturing, automotive trim bonding, and flexible electronics assembly. Its modular architecture supports both standalone operation and full integration into laboratory data management workflows. The system operates on the principle of controlled uniaxial force application, where load is transmitted through a high-rigidity frame, measured by a calibrated load cell, and resolved with sub-micron positional fidelity via optical encoder feedback on a preloaded ball screw drive train.

Key Features

• High-fidelity force measurement with ±0.5% full-scale accuracy and 1/500,000 resolution across the 20 kN range
• Drum peel configuration compliant with ASTM D3330 Method B (180° peel) and GB/T 2792 for consistent angular separation of bonded layers
• Stepper motor-driven actuation coupled with precision ground ball screw transmission (≥85% mechanical efficiency)
• Adjustable test speed from 0.1 to 500 mm/min, programmable via PC interface or front-panel controls
• Integrated auto-return function triggered upon specimen failure, overload, or user-defined upper/lower displacement limits
• Quick-change fixture interface supporting interchangeable grips—including pneumatic, wedge, and custom drum mandrels—for multi-standard testing
• Dual-mode operation: self-contained LCD control (optional) or fully synchronized PC-based acquisition with real-time force–displacement curve plotting
• USB 2.0 and RS-232 connectivity for seamless integration with LIMS, ELN, or statistical process control platforms

Sample Compatibility & Compliance

The YL-S90 accommodates specimens up to 110 mm wide and 800 mm travel length, enabling evaluation of pressure-sensitive adhesives (PSAs), laminated films, metallized foils, textile composites, and biomedical tapes. It meets regulatory requirements for routine QC in ISO 9001-certified facilities and supports GLP-compliant documentation when paired with audit-trail-enabled software. Test protocols align with ASTM D3330 (peel adhesion of PSAs), GB/T 2792 (180° peel strength), GB/T 12914 (tensile properties of paper and board), GB/T 1040 (plastic tensile testing), and QB/T 2171 (adhesive tape performance). All force and displacement outputs are traceable to national metrological standards through factory calibration certificates (NIST-traceable load cell verification available upon request).

Software & Data Management

The included Windows-compatible software provides ISO/IEC 17025-aligned data acquisition, including real-time graphing, automatic peak detection, modulus calculation, and statistical reporting (mean, SD, CV%, min/max). Raw datasets export in CSV, Excel, and PDF formats; metadata fields support sample ID, operator, date/time stamp, environmental conditions (optional sensor input), and calibration status. Audit trail functionality logs all parameter changes, test initiations, and result modifications—meeting FDA 21 CFR Part 11 requirements when deployed with electronic signature modules. Optional cloud synchronization enables centralized review across multi-site laboratories while preserving local data sovereignty.

Applications

• Quantification of peel resistance in pharmaceutical blister packaging seals and transdermal patch backing layers
• Evaluation of interlaminar bond strength in lithium-ion battery electrode stacks and flexible printed circuit boards
• Validation of adhesive performance in automotive interior trim lamination under thermal cycling and humidity exposure
• Quality control of label adhesion on PET, HDPE, and aluminum containers per ISTA and ASTM D6190 guidelines
• Mechanical characterization of biodegradable films, hydrocolloid dressings, and surgical drapes per ISO 10993-10 biocompatibility testing frameworks
• Research-grade tensile modulus and elongation-at-break analysis for thermoplastic elastomers and fiber-reinforced composites

FAQ

What peel angles does the YL-S90 support?
The standard drum peel fixture is configured for 180° peel per ASTM D3330 and GB/T 2792. Custom 90° or T-peel fixtures are available as optional accessories.
Is the system compatible with third-party data analysis tools like MATLAB or Python?
Yes—raw time-force-displacement data exports in ASCII-delimited format, enabling direct ingestion into MATLAB, Python (NumPy/Pandas), or JMP for advanced curve fitting and statistical modeling.
Does the YL-S90 meet ISO/IEC 17025 calibration requirements?
The base system includes factory calibration with uncertainty budget; accredited third-party calibration services (ISO/IEC 17025) are available through authorized service partners.
Can the machine perform hold-load (creep) tests?
Yes—programmable dwell periods at specified load or displacement targets enable creep, stress relaxation, and tack retention assessments per ASTM D6190 Annex A3.
What maintenance intervals are recommended for long-term repeatability?
Ball screw lubrication every 6 months and annual load cell verification are advised; full preventive maintenance kits and service manuals are supplied with each unit.
