Overview
The Tuofeng TFW-240 Microcomputer-Controlled Electronic Universal Testing Machine is a high-precision, dual-column electromechanical system engineered for static mechanical property characterization of metallic, polymeric, composite, ceramic, and elastomeric materials. It operates on the principle of controlled axial force application via servo-driven ball-screw actuation, enabling precise displacement and load control across a wide dynamic range. Designed to meet international metrological standards—including GB/T 16491–2008, JJG 475–2008, ISO 5893, and ASTM E4—the machine delivers traceable, repeatable results suitable for R&D validation, quality assurance, and regulatory submission. Its modular architecture supports standardized tensile, compression, flexure, shear, peel, tear, puncture, and creep testing protocols, making it integral to material qualification workflows in aerospace, automotive, biomedical device manufacturing, construction materials certification, and polymer R&D laboratories.
Key Features
- 0.5-class accuracy certified per ISO 7500-1 and GB/T 16491–2008, with force resolution of 1 part in ±500,000 full-scale—ensuring high reproducibility at low-load regimes (down to 0.2% FS).
- Imported high-torque servo motor coupled with a backlash-free worm gear reducer and preloaded precision-ground ball screw, delivering smooth, noiseless motion and minimal thermal drift during extended tests.
- Dual-speed crosshead control (fast positioning + fine adjustment) with programmable return-to-start functionality, reducing cycle time between specimens without manual intervention.
- Integrated electronic limit switches, hardware-based emergency stop circuitry, and software-enforced overload cutoff (110% FS threshold) ensure operator and equipment safety per IEC 61800-5-2 and EN ISO 13857.
- Modular extensometry support: compatible with clip-on axial extensometers (ASTM E83 Class B-1), video-based digital image correlation (DIC) systems, and large-deformation transducers for strain measurement up to 1000% elongation.
- Rigid cast-iron base and reinforced steel frame minimize deflection under maximum load (240 kN), maintaining alignment integrity and reducing measurement uncertainty in high-stiffness material testing.
Sample Compatibility & Compliance
The TFW-240 accommodates specimens from thin films (<0.1 mm thickness) to structural beams (up to 600 mm width × 800 mm height), with customizable fixtures for ASTM D638, ISO 527, ASTM D790, ISO 178, ASTM D1876 (T-peel), ISO 8510-2 (lap shear), and ASTM D624 (tear). All test methods are implemented in strict conformance with ISO/IEC 17025–2017 requirements for testing laboratories. The system meets mechanical calibration traceability standards aligned with NIST SP 250-94 and supports GLP/GMP-compliant operation when configured with 21 CFR Part 11–enabled software modules—including audit trail logging, role-based user access, electronic signatures, and immutable data archiving.
Software & Data Management
TuofengTest Pro v5.2 is a Windows-native, multi-language (English, Simplified/Traditional Chinese) platform supporting real-time control of load, displacement, strain, and time-based test profiles. It enables seamless execution of ISO 6892-1 tensile ramps, ASTM E21 creep hold sequences, ISO 11443 melt flow simulations, and custom step-and-hold protocols. Real-time plotting includes synchronized stress–strain, load–displacement, and time-series overlays with automatic yield point detection (0.2% offset, tangent, or maximum curvature methods). Raw data exports to CSV, XML, and universal .udf formats; report templates comply with ISO 14289-1 (PDF/A-2u) for long-term archival. Version-controlled firmware and software updates are provided free of charge for the instrument’s operational lifetime.
Applications
- Mechanical validation of aerospace alloys (Ti-6Al-4V, Inconel 718) per AMS 2300 and ASTM B557.
- Tensile and flexural property mapping of thermoplastic composites (CFRP, GFRP) for automotive lightweighting programs.
- Peel strength assessment of medical adhesive tapes and wound dressings per ISO 22869 and ASTM F2255.
- Compression testing of pharmaceutical tablets per USP and Ph. Eur. 2.9.40.
- Creep rupture analysis of geosynthetic polymers under sustained loading (ISO 13431).
- Quality control of extruded aluminum profiles per EN 755-2 and ASTM B221.
