HAIDA International Shoe Sole Adhesion Tester

Overview

The HAIDA International Shoe Sole Adhesion Tester is a precision mechanical testing instrument engineered for quantitative evaluation of bond strength between shoe uppers and soles—commonly referred to as sole adhesion or peel resistance. It operates on the principle of controlled angular peeling under standardized tensile loading, conforming to the fundamental mechanics of interfacial fracture in laminated elastomeric composites. Designed specifically for footwear quality assurance laboratories, R&D centers, and third-party certification bodies, this tester delivers repeatable, traceable force-displacement data essential for compliance with international footwear performance standards. Its robust frame, servo-controlled actuation system, and calibrated load cell ensure high reproducibility across repetitive peel cycles—critical for assessing adhesive durability under simulated wear conditions.

Key Features

• High-precision digital load cell with resolution ≤ 0.1 N and accuracy ±0.5% FS, enabling reliable measurement of peel forces ranging from 1 N to 500 N (configurable range).
• Adjustable peel angle mechanism (90° and 180° standard configurations) with fine-tuned mechanical locking to maintain consistent geometry throughout test execution.
• Motorized crosshead drive with programmable speed control (1–500 mm/min), supporting both ISO 8510-2 and ASTM D903 compliant test velocities.
• Integrated sample clamping system featuring serrated pneumatic grips and quick-release fixtures, minimizing slippage during high-force peel events.
• Stainless-steel structural frame with vibration-dampening base, ensuring mechanical stability during dynamic loading and long-term calibration retention.
• Compliance-ready design: All mechanical and software components support audit trails, user access levels, and raw data export—aligned with GLP and ISO/IEC 17025 laboratory management requirements.

Sample Compatibility & Compliance

The HAIDA Shoe Sole Adhesion Tester accommodates a broad spectrum of footwear constructions—including leather, synthetic upper materials, rubber, TPU, EVA, and PU soles—with specimen widths up to 50 mm and thicknesses up to 25 mm. It supports standardized specimen preparation per ISO 8510-2 (Peel Resistance of Adhesives — 90° Peel Test), ASTM D903 (Standard Test Method for Peel or Stripping Strength of Adhesive Bonds), and GB/T 3903.3 (Footwear — Test Methods for Physical and Mechanical Properties — Part 3: Adhesion Strength of Sole to Upper). Instrument validation documentation includes full traceability to national metrology institutes (e.g., CNAS-accredited calibration certificates), and mechanical design adheres to EN 61000-6-2 (EMC immunity) and EN 61000-6-4 (EMC emission) directives.

Software & Data Management

The system integrates with HAIDA’s proprietary TESTLINK v4.2 software suite, which provides real-time force–displacement curve visualization, automatic peak force detection, and statistical analysis (mean, SD, CV%) across batched tests. Raw data is stored in ASCII CSV format with embedded metadata—including operator ID, timestamp, environmental conditions (optional via external sensor input), and instrument serial number—to satisfy FDA 21 CFR Part 11 electronic record requirements. Audit log functionality records all parameter modifications, test executions, and user logins. Software supports configurable report templates aligned with ISO/IEC 17025 clause 7.8.2 for test reporting integrity.

Applications

• Quality control of adhesive bonding processes in footwear manufacturing lines.
• Comparative evaluation of alternative adhesives (e.g., solvent-based vs. water-based vs. hot-melt systems) under accelerated aging conditions.
• Validation of sole bonding performance after thermal cycling, humidity exposure, or flex fatigue pre-conditioning (per ISO 20344 Annex B).
• Supporting technical documentation for CE marking, CCC certification, and export compliance to EU, US, and ASEAN markets.
• Research applications in polymer interface science, including failure mode analysis (cohesive vs. interfacial debonding) via post-test specimen inspection.

FAQ

What standards does this tester directly support?
ISO 8510-2, ASTM D903, GB/T 3903.3, EN ISO 20344 Annex B, and JIS L 4101.
Is calibration certificate included with delivery?
Yes—a factory-issued, CNAS-traceable calibration certificate is provided; optional annual recalibration services are available through HAIDA’s global service network.
Can the instrument be integrated into an existing LIMS environment?
Yes, via TCP/IP or RS-232 communication protocols with customizable API endpoints for bidirectional data exchange.
Does the system meet regulatory requirements for pharmaceutical or medical device packaging testing?
While primarily designed for footwear, its mechanical architecture and software audit trail capabilities align with general-purpose material adhesion testing requirements under ISO 11607-2 for sterile barrier systems.
What maintenance intervals are recommended?
Load cell verification every 6 months; mechanical alignment check and grip surface inspection prior to each test series; full preventive maintenance annually by certified technician.
