Jiubin JB-117 Universal Testing Machine for Tape Peel Strength Measurement

Overview

The Jiubin JB-117 Universal Testing Machine is a precision-engineered electromechanical system designed specifically for quantitative mechanical evaluation of adhesive bond integrity in pressure-sensitive tapes, labels, laminates, and flexible packaging materials. It operates on the principle of controlled uniaxial tension applied to standardized specimen configurations—most commonly 90° or 180° peel geometries per ISO 8510-1 and ASTM D3330—where force is measured continuously as the tape is progressively delaminated from a rigid substrate at a constant rate. The machine integrates a high-fidelity load cell, servo-controlled crosshead actuation, and sub-micron displacement resolution to deliver repeatable, traceable peel strength data (expressed in N/25 mm or N/cm) essential for QC release testing, formulation development, and regulatory documentation in adhesive manufacturing, medical device labeling, and electronics assembly industries.

Key Features

• Electromechanical architecture with AC servo motor and precision ball-screw drive, enabling stable, low-noise motion control across the full speed range (0.001–500 mm/min)
• Multi-mode force control: stress-, strain-, and displacement-based closed-loop regulation, switchable in real time during test execution
• Full-scale force measurement capability from 5 kN to 50 kN, with dual-range load cells offering ≤±1% FS accuracy (≤±0.5% FS optional for metrology-grade validation)
• High-resolution displacement sensing (0.001 mm) and deformation tracking (2–100% strain range), supporting both standard peel and large-deformation adhesion tests
• Integrated safety architecture including mechanical end-stop limiters, electronic overload cutoff, overcurrent/overvoltage protection, and a certified emergency stop button compliant with IEC 60204-1
• Modular fixture system: standardized peel jigs for 90° and 180° configurations, drum peel mandrels, tensile grips, compression platens, and custom tooling interfaces for non-standard substrates

Sample Compatibility & Compliance

The JB-117 accommodates specimens conforming to international peel test standards, including but not limited to ISO 8510-1 (adhesive tapes), ASTM D3330 (peel adhesion of pressure-sensitive tapes), ASTM D903 (peel resistance of adhesive bonds), and JIS Z0237 (test methods for pressure-sensitive adhesive tapes). It supports rigid substrates (e.g., stainless steel, aluminum, glass), flexible backings (PET, PI, PVC), and composite laminates. All test protocols are configurable to meet GLP and GMP documentation requirements, with optional software modules enabling 21 CFR Part 11-compliant user authentication, electronic signatures, and immutable audit trails for regulated environments.

Software & Data Management

The system runs on a dedicated Windows-based control and analysis platform featuring real-time force–displacement curve visualization, automatic peak detection, plateau averaging (per ASTM D3330 Section 7.3), and customizable reporting templates. Raw data is stored in encrypted binary format with metadata tagging (operator ID, timestamp, calibration status, environmental conditions). Export options include CSV, PDF, and XML formats compatible with LIMS integration. Optional validation packages include IQ/OQ documentation, calibration certificate traceability to NIM (China National Institute of Metrology), and software verification reports aligned with ISO/IEC 17025 requirements.

Applications

• Quantitative peel strength verification of medical transdermal patches, surgical tapes, and wound dressings
• QC release testing of industrial double-sided tapes used in automotive trim bonding and electronics shielding
• Adhesive formulation screening for temperature-dependent peel performance (combined with environmental chamber integration)
• Evaluation of aging effects on tape adhesion after thermal cycling, UV exposure, or humidity conditioning
• Mechanical characterization of release liners, silicone-coated papers, and anti-adhesive coatings
• Support for R&D workflows requiring correlation between peel behavior and tensile modulus, elongation at break, or shear resistance

FAQ

What peel angles does the JB-117 support?
The system is configured for standardized 90° and 180° peel tests per ISO 8510 and ASTM D3330, with optional drum peel fixtures for curvature-dependent adhesion assessment.
Is the machine suitable for testing thin films or ultra-low-force tapes?
Yes—when equipped with the 5 kN load cell and high-sensitivity acquisition firmware, the system achieves reliable measurement down to 0.02 N with <1% repeatability CV across replicate 90° peel trials.
Can test methods be saved and recalled for routine QC use?
Absolutely—the software supports method libraries with locked parameters (speed, gauge length, trigger thresholds), ensuring operator-independent execution across shifts and laboratories.
Does the system meet regulatory requirements for pharmaceutical or medical device manufacturing?
With the optional 21 CFR Part 11 compliance module and validated installation/operational qualification (IQ/OQ) package, it fulfills core data integrity and audit readiness criteria for FDA- and NMPA-regulated facilities.
Are calibration services and traceable certificates available?
Jiubin provides annual calibration services with certificates traceable to national standards (NIM), including force, displacement, and speed verification across the operational range.
