Jiubin JB-117S Wood-Plastic Composite (WPC) Flexural Strength Testing Machine

Overview

The Jiubin JB-117S Wood-Plastic Composite (WPC) Flexural Strength Testing Machine is a high-precision universal testing system engineered for standardized mechanical evaluation of structural composite panels used in building materials, decking, and outdoor applications. It operates on the principle of three-point or four-point bending per ISO 16978, ASTM D6108, EN 310, and GB/T 17657, delivering reproducible measurements of modulus of rupture (MOR), modulus of elasticity (MOE), surface bonding strength, internal bond strength, and screw withdrawal resistance. The machine integrates a rigid dual-space frame architecture—tensile above, compression below—with a servo-controlled crosshead driven by a Panasonic AC servo motor and ABBA precision ball screw assembly. Its fully digital PCI-based data acquisition system captures force, displacement, and strain signals at up to 10 kHz sampling rate, ensuring traceable, high-fidelity waveform capture essential for R&D validation and QC compliance reporting.

Key Features

• True closed-loop control architecture supporting constant-rate loading, constant-displacement, and constant-force test modes with seamless switching between control algorithms
• Auto-ranging load cell system (Transcell, USA) with 1/500,000 internal resolution and automatic zeroing, calibration, and range selection based on applied load magnitude
• Dual-display operation: simultaneous real-time monitoring via integrated industrial touchscreen and Windows PC interface
• Comprehensive safety suite including overload protection, over-speed cutoff, current/voltage anomaly detection, travel limit switches, and dust-resistant ABBA ball screw housing (Taiwan-made bellows seal)
• Proprietary software platform developed in-house with full source code access—enabling user-defined test protocols, report templates, and compliance mapping to GB, ASTM D1037/D6309, EN 13986, JIS A 5908, and ISO 13968
• Dynamic curve visualization during testing: real-time plotting of force–displacement, stress–strain, and load–time profiles with post-test curve re-analysis capability
• Batch testing functionality with condition template storage—ideal for repetitive quality checks across production lots
• Network-ready architecture supporting TCP/IP communication, local database archiving, and secure export to CSV, PDF, or XML formats compatible with LIMS integration

Sample Compatibility & Compliance

The JB-117S accommodates standard WPC specimens (e.g., 25 × 25 × 300 mm per ASTM D6108), as well as engineered wood products including particleboard, MDF, plywood, OSB, and laminated veneer lumber. Its 380 mm effective test width and 1000 mm vertical clearance allow full-height testing of thick composites without fixture interference. All measurement outputs comply with ISO/IEC 17025 requirements for testing laboratories, and software audit trails meet FDA 21 CFR Part 11 criteria for electronic records and signatures when configured with user authentication and change logging. Calibration certificates are traceable to NIM (China National Institute of Metrology) and include uncertainty budgets per ISO/IEC 17025 Annex A.4.

Software & Data Management

The embedded Windows-based software provides a guided workflow—from specimen setup and standard selection to result export—with intuitive menu navigation and context-sensitive help. Each test generates a timestamped digital record containing raw sensor data, environmental metadata (operator ID, lab temperature/humidity if logged), and calculated parameters (MOR, MOE, failure mode classification). Data files are stored in encrypted SQLite databases with configurable retention policies. Reporting modules support customizable layouts compliant with ISO 5893 and ASTM E4 formats; users may import corporate letterheads or map fields directly to ERP/MES systems via ODBC. Firmware and application updates are delivered free-of-charge for the lifetime of the instrument, with version-controlled changelogs and backward-compatible data migration.

Applications

• Flexural performance certification of WPC decking boards under cyclic loading per ASTM D6662
• Quality assurance of recycled-content composite panels in ISO 16978-compliant production lines
• R&D validation of binder formulations, fiber reinforcement ratios, and extrusion process parameters
• Third-party verification for CE marking, CARB ATCM compliance, and LEED MR credits
• Interlaboratory comparison studies requiring inter-lab reproducibility < 3% CV per ISO 5725
• Failure mode analysis—including delamination onset, fiber pull-out, and matrix cracking—via synchronized video capture (optional add-on)

FAQ

Does the JB-117S support ASTM D6108 and EN 310 test methods natively?
Yes—the software includes preconfigured test templates for both standards, with automatic calculation of MOR, MOE, and coefficient of variation according to their respective annexes.

Can I integrate this tester into our existing LIMS or SAP QM system?
Yes—via standard ODBC drivers and RESTful API endpoints (available upon request), enabling automated data ingestion and electronic batch record linkage.

Is the force transducer calibrated and certified before shipment?
All units ship with an NIM-traceable calibration certificate valid for 12 months, including linearity, hysteresis, and repeatability data per ISO 376.

What maintenance intervals are recommended for long-term accuracy?
Annual recalibration is advised; routine inspection of ball screw lubrication, belt tension, and encoder alignment should occur every 6 months per the maintenance logbook provided.

Do you offer GMP/GLP-compliant configuration options?
Yes—optional 21 CFR Part 11 modules include role-based access control, electronic signature workflows, and immutable audit trails with hash-verified data integrity logs.
