Jiubin JB-118A Universal Tensile Testing Machine for Wires and Beaded Cables

Overview

The Jiubin JB-118A Universal Tensile Testing Machine is an electromechanical static testing system engineered for high-reproducibility mechanical characterization of low-to-medium force specimens—particularly wire-based assemblies, beaded cables, thin metallic foils, polymer filaments, elastomeric strips, and adhesive-laminated substrates. It operates on the fundamental principle of controlled uniaxial loading: a precision servo-motor-driven crosshead applies calibrated tensile, compressive, or flexural force to a specimen clamped between standardized grips, while integrated load cells and encoder-based displacement transducers capture real-time force–displacement data. The system conforms to core static mechanical testing paradigms defined in ISO 6892-1 (metallic materials), ASTM D638 (plastics), and ISO 11339 (adhesive peel), with hardware architecture optimized for stable load application at sub-newton to 5 kN ranges—making it especially suited for quality control labs validating cable termination integrity, crimp joint strength, bead retention force, and interfacial adhesion in multi-layer flexible electronics.

Key Features

• Modular dual-column frame with rigid aluminum alloy construction and preloaded ball-screw drive for minimal deflection and long-term dimensional stability
• High-resolution load measurement via S-type or cantilever beam load cells (±0.5% full-scale accuracy per ISO 376), traceable to national metrology standards
• Programmable crosshead speed from 0.001 to 500 mm/min, enabling quasi-static creep, relaxation, and rate-dependent property assessment
• Digital position feedback with 0.001 mm resolution and 100 Hz synchronous data acquisition across force, displacement, and time channels
• Standardized grip systems: pneumatic wedge grips for wires and ribbons; spring-loaded peel fixtures for 180°/T-peel; three-point bending fixtures for PCB flexural modulus
• Fully integrated control and analysis software with customizable test templates, real-time curve overlay, and automatic yield point detection per ASTM E8/E21

Sample Compatibility & Compliance

The JB-118A accommodates specimens ranging from 0.05 mm diameter fine wires to 100 mm wide composite laminates. Its mechanical interface supports standard specimen geometries per GB/T 13022 (plastic films), GB/T 2790 (180° peel of adhesive bonds), GB/T 8808 (peel strength of flexible packaging), and YY/T 0148 (medical tape adhesion). The system meets essential performance verification requirements outlined in JB 706–77 (Chinese national standard for mechanical testing machines) and provides documented traceability for calibration procedures aligned with ISO/IEC 17025. All test methods referenced—including GB/T 2791 (T-peel), GB/T 7754 (lap shear), and ZBY 28004 (heat seal strength)—are preconfigured within the software library with parameter presets, pass/fail thresholds, and report generation compliant with internal QC protocols.

Software & Data Management

The proprietary Windows-based testing platform delivers full GLP-aligned data governance: user-level access control, electronic signatures, immutable audit trails for all test modifications, and automatic timestamped export of raw ASCII/CSV files alongside PDF reports. Each test record embeds metadata including operator ID, environmental conditions (optional sensor input), calibration certificate IDs, and instrument configuration logs. The software supports multi-curve statistical comparison (mean ± SD, coefficient of variation), automatic calculation of tensile strength (MPa), elongation at break (%), modulus (MPa), peel adhesion (N/mm), and shear strength (MPa). Export formats include Excel-compatible spreadsheets, image-annotated stress–strain plots, and XML for LIMS integration. All software updates and method validations are version-controlled and archived per laboratory document management policy.

Applications

• Quantification of axial pull-out force for beaded surgical sutures and textile reinforcement cords
• Validation of crimp joint integrity in automotive wiring harnesses and battery interconnects
• Peel resistance testing of pressure-sensitive adhesive tapes used in medical device assembly
• Mechanical screening of flexible printed circuit boards (FPCBs) under bending and torsional loads
• Interlaminar shear strength assessment of thermoplastic composites and coated fabrics
• Quality release testing of packaging films, pouch seals, and laminated barrier structures
• Long-term creep behavior evaluation of elastomeric connectors and silicone-insulated leads

FAQ

Does the JB-118A comply with FDA 21 CFR Part 11 requirements?
It supports ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate) and offers optional 21 CFR Part 11 add-ons—including electronic signature workflows, role-based permissions, and audit trail encryption—for regulated environments.
Can the system perform cyclic loading or fatigue tests?
Yes—the software includes programmable load–displacement waveforms (sine, triangle, trapezoidal) with up to 1 million cycle logging capability; however, dedicated high-cycle fatigue testing requires optional hydraulic actuation modules not included in the base JB-118A configuration.
Is third-party calibration certification available?
Jiubin provides factory calibration certificates traceable to CNAS-accredited laboratories; users may also engage ISO/IEC 17025-certified service providers for on-site verification and recalibration.
What grip types are supplied as standard?
Standard delivery includes pneumatic vise grips (for wires and flat strips), 180° peel fixtures (10 mm width), and three-point bending fixtures (span adjustable from 10–100 mm); custom grips (e.g., micro-tensile, torsion, or environmental chambers) are available upon request.
How is software validation handled for GMP environments?
A comprehensive IQ/OQ protocol package—including installation qualification checklists, operational boundary testing, and method-specific performance verification—is provided to support laboratory validation against ICH Q9 and Annex 11 expectations.
