Jiubin JB-120 Leather Footwear Peel Strength Testing Machine

Overview

The Jiubin JB-120 Leather Footwear Peel Strength Testing Machine is a dedicated electromechanical universal testing system engineered for quantitative mechanical evaluation of adhesive bond integrity between shoe uppers and soles in finished footwear. It operates on the principle of controlled tensile separation—applying a precisely regulated axial force to initiate and propagate interfacial delamination along the upper–outsole junction. The machine conforms to standardized peel geometries defined in ISO 8510-2, ASTM D903, GB/T 3903.3, and EN ISO 22867, enabling reproducible measurement of peel force (N) and subsequent calculation of peel strength (N/mm) using nominal blade width. Its modular load frame architecture supports both static and quasi-static loading protocols, with closed-loop control ensuring high fidelity in force–displacement response tracking during low-speed, high-sensitivity peel events.

Key Features

• High-precision AC servo motor drive with digital speed regulation (0.001–500 mm/min), delivering stable velocity profiles across the full operational range;
• Triple-mode closed-loop control: force, displacement, and strain—switchable in real time without hardware reconfiguration;
• Full-scale unsegmented force transduction from 0.4% to 100% FS, minimizing range-switching artifacts and enhancing data continuity;
• Integrated data acquisition system with real-time curve plotting (force vs. displacement, peel force vs. distance) and automated report generation compliant with GLP documentation standards;
• Multi-standard test protocol library supporting GB, ISO, ASTM, JIS, DIN, and user-defined methods—including automatic parameter loading per standard;
• Comprehensive safety architecture: dual mechanical end-stop limits, programmable overload cut-off, thermal-overcurrent protection, line-voltage monitoring, and a certified emergency stop circuit meeting IEC 60204-1 requirements.

Sample Compatibility & Compliance

The JB-120 accommodates whole-footwear specimens mounted on standardized last inserts, with adaptable fixture interfaces for toe, heel, and midfoot clamping configurations. Its peel tooling set includes calibrated 90° and 180° peel fixtures, as well as a rotating drum assembly for dynamic peel assessment under constant angle conditions. All mechanical components are manufactured to ISO 2768-mK general tolerances, and structural rigidity meets ISO 7500-1 Class 1 requirements for static testing machines. The system supports audit-ready compliance with ISO/IEC 17025 laboratory accreditation criteria, including traceable calibration records (certified to ISO/IEC 17025:2017 via CNAS-accredited providers), documented uncertainty budgets, and full instrument qualification (IQ/OQ/PQ) support packages.

Software & Data Management

Bundled with Jiubin TestSuite v4.x, the system provides secure, role-based access control, electronic signature capability, and 21 CFR Part 11-compliant audit trails for all test parameter changes, result modifications, and report exports. Raw data is stored in encrypted binary format with embedded metadata (operator ID, timestamp, environmental conditions, calibration status). Export options include CSV, PDF/A-2, and XML formats compatible with LIMS integration. Calibration history, maintenance logs, and preventive service alerts are managed within the same database, ensuring full lifecycle traceability required under GMP and GLP frameworks.

Applications

• Quantitative peel strength verification of cemented, stitched, or injection-molded upper–sole bonds in leather, synthetic, and textile footwear;
• Comparative adhesion performance assessment across adhesive formulations (e.g., polyurethane vs. chloroprene vs. water-based systems);
• Quality control screening of production batches against internal specifications or customer-facing durability thresholds;
• Failure mode analysis—distinguishing cohesive failure (within adhesive layer) from interfacial failure (at substrate boundary) via synchronized video recording and force waveform morphology;
• Supporting R&D validation of new last designs, sole materials, and bonding process parameters (curing temperature, dwell time, surface pretreatment).

FAQ

What peel angles does the JB-120 support, and how are they implemented?
The system offers three standardized peel configurations: 90° fixed-angle peel using a vertical clamp and horizontal peel arm; 180° peel with dual horizontal grips and a pivot-mounted specimen holder; and drum peel using a motorized rotating cylinder to maintain constant peel angle during motion. All fixtures are interchangeable without tools and referenced to ISO 8510-2 alignment tolerances.
Can the JB-120 be integrated into an existing LIMS or MES environment?
Yes—via TCP/IP-based API (RESTful endpoints) and OPC UA server support, enabling bidirectional data exchange with enterprise systems. Pre-built connectors are available for LabWare LIMS, Thermo Fisher SampleManager, and Siemens Opcenter.
Is calibration certification included with delivery?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China) standards. Optional third-party ISO/IEC 17025 calibration with uncertainty reporting is available upon order.
What is the minimum resolvable peel force increment at 5 kN capacity?
With the standard 5 kN load cell and 24-bit ADC, the system resolves force increments down to 0.05 N (0.001% FS), sufficient to detect early-stage micro-delamination events in high-performance footwear adhesives.
Are custom fixtures for non-standard footwear types (e.g., athletic cleats or orthopedic shoes) supported?
Yes—Jiubin’s engineering team provides custom fixture design and FEA-supported validation per client specifications, with lead times typically 4–6 weeks from approved drawings.
