QJ212-500KN倾技电子万能材料拉伸试验机

Overview

The QJ212-500KN Qinsen Electromechanical Universal Tensile Testing Machine is a high-capacity, precision-engineered static mechanical testing system designed for comprehensive evaluation of tensile, compressive, flexural, peel, tear, and hold-load behavior in advanced engineering materials. Built upon a rigid dual-column frame architecture with reinforced crosshead guidance and high-stiffness load train, the system delivers exceptional force linearity and axial alignment stability—critical for reliable determination of modulus, yield strength, ultimate tensile strength (UTS), elongation at break, and plastic deformation characteristics per ASTM E8/E21, ISO 6892-1, GB/T 228.1, DIN 50125, and JIS Z 2241 standards. Its modular design supports both standard compliance testing and R&D-grade material characterization workflows across aerospace composites, carbon fiber laminates, polymer matrices, thermosets, elastomers, and metallic alloys.

Key Features

• 500 kN maximum capacity electromechanical actuation system with continuous load range from 0.02% to 100% FS—no manual range switching required
• High-resolution force measurement using calibrated U.S.-origin load cells, delivering ±0.5% accuracy across full scale
• Panasonic digital AC servo motor and controller enabling precise speed control from 0.01 to 1000 mm/min (standard calibration at 300 mm/min)
• Full-digital closed-loop control architecture supporting constant load, constant strain, and constant displacement test modes
• Integrated electronic limit switches and real-time software diagnostics for automatic overtravel and overload protection (110% FS threshold)
• Motorized crosshead with dual-speed adjustment (fast/slow) and programmable return-to-start functionality
• Robust structural frame (1450 kg mass) minimizing vibration coupling and ensuring long-term repeatability under cyclic loading
• Modular fixture interface accommodating custom-designed grips, bending jigs, peel fixtures, and environmental chamber adapters

Sample Compatibility & Compliance

The QJ212-500KN accommodates specimens ranging from thin films (≥0.1 mm thickness) to structural composite laminates (up to 520 mm wide × 800 mm gage length). It supports standardized specimen geometries per ISO 527-2 (plastics), ASTM D3039 (composite tension), ASTM D638 (thermoplastics), and GB/T 3354 (carbon fiber). All test protocols are traceable to national metrological standards, with documented uncertainty budgets aligned with ISO/IEC 17025 requirements. The system meets mechanical safety criteria per EN ISO 12100 and incorporates hardware interlocks compliant with IEC 61800-5-2 for drive system safety integrity.

Software & Data Management

Bundled with Qinsen’s proprietary TestMaster Pro v4.x software, the system provides automated calculation of ReH (upper yield strength), ReL (lower yield strength), Rp0.2 (0.2% offset yield), Fm (maximum force), Rm (tensile strength), Rt0.5–Rt0.7 (proof strengths), E (Young’s modulus), A (elongation at break), and Ag (uniform elongation). Raw data export supports CSV, XML, and PDF report generation with embedded metadata (operator ID, timestamp, environmental conditions, calibration certificate IDs). Audit trail functionality complies with FDA 21 CFR Part 11 requirements when deployed with user authentication, electronic signatures, and immutable log archiving. Data integrity is preserved via local storage redundancy and optional network backup integration.

Applications

• Tensile property validation of prepreg-impregnated carbon fiber coupons (ASTM D3039, ISO 527-4)
• Compression-after-impact (CAI) specimen preparation and pre-load conditioning
• Interlaminar shear strength (ILSS) assessment using short-beam shear fixtures
• Adhesive bond strength evaluation per ASTM D1002 and ISO 4587
• Creep and stress-relaxation profiling under controlled temperature environments (when coupled with environmental chambers)
• Quality assurance testing for automotive CFRP chassis components and wind turbine blade spar caps
• Educational and certification labs requiring GLP-compliant reporting for ISO 17025 accreditation

FAQ

What international standards does this system support out-of-the-box?
The QJ212-500KN is pre-configured with test methods for ASTM E8/E21, ISO 6892-1, GB/T 228.1, DIN 50125, and JIS Z 2241. Additional method templates can be imported or customized via the software’s open scripting interface.

Is the system compatible with third-party environmental chambers?
Yes—the machine features standardized mounting interfaces and analog/digital I/O ports (0–10 V, RS-232, Ethernet) for seamless synchronization with thermal, humidity, or vacuum chambers from manufacturers including ESPEC, Weisstechnik, and Angelantoni.

How is traceability maintained for calibration and maintenance records?
All calibration events—including load cell, extensometer, and displacement encoder verifications—are logged automatically with operator ID, date/time stamp, reference standard ID, and measurement uncertainty values. These logs are exportable as encrypted PDFs for internal QA review or external audit submission.

Can the system perform multi-step cyclic tests with dwell periods?
Yes—TestMaster Pro supports up to 99 programmable steps per test sequence, including ramp-hold-ramp profiles, staircase loading, and conditional branching based on real-time force or displacement thresholds.

What post-purchase technical support options are available?
Qinsen provides one year of comprehensive hardware warranty, remote diagnostics, on-site installation and commissioning, operator training (2–4 personnel), and lifetime firmware updates. Extended service contracts include annual performance verification and preventive maintenance visits.
