Overview
The Tuofeng TFW-310 Microcomputer-Controlled Universal Testing Machine is an electromechanical static testing system engineered for high-reproducibility mechanical characterization of metallic, polymeric, ceramic, composite, and elastomeric materials. Based on closed-loop servo-controlled force and displacement actuation, the system implements precise load application via a high-rigidity frame, preloaded ball screw transmission, and low-backlash gear reduction. Its measurement architecture complies with ISO 7500-1 Class 0.5 and ASTM E4 requirements for verification of static force-measuring systems, ensuring traceable accuracy across the full 0.2–100% load range. Designed for structural integrity assessment and process validation, the TFW-310 supports quasi-static uniaxial loading modes including tension, compression, flexure, shear, peel, tear, and puncture—enabling full stress–strain curve acquisition and standardized mechanical property derivation per international test protocols.
Key Features
- Robust dual-column steel frame with reinforced crosshead and base plate, optimized for minimal deflection under 300 kN maximum load
- Imported high-torque servo motor coupled with precision worm gear reducer ensures smooth, silent operation and zero backlash during speed transitions
- High-accuracy ball screw assembly with preloaded nut design guarantees axial positioning repeatability better than ±0.005 mm
- Real-time digital control loop operating at ≥1 kHz sampling rate for synchronized force, displacement, and strain data capture
- Dual-speed crosshead drive (fast jog + fine positioning) with programmable acceleration/deceleration profiles
- Integrated hardware safety chain: electronic end-limit switches, emergency stop circuit, overload cut-off (110% FS), and mechanical torque limiter
- Modular fixture interface compatible with standard wedge-action, pneumatic, hydraulic, and custom-designed grips
- Full-range, single-scale force transducer with 500,000-count A/D resolution and temperature-compensated strain gauge bridge
Sample Compatibility & Compliance
The TFW-310 accommodates specimens from thin films (≥0.05 mm thickness) to structural beams (up to 150 mm wide × 50 mm thick), with customizable test widths up to 600 mm and stroke extensions beyond 800 mm. It supports standard specimen geometries defined in ASTM D638 (tensile bars), ASTM D790 (flexural beams), ISO 604 (rigid plastics compression), ISO 178 (flexural testing), and GB/T 228.1 (metal tensile). The system meets metrological verification requirements per JJG 475–2008 (China National Verification Regulation) and mechanical performance specifications per GB/T 16491–2008. All force, displacement, and strain measurements are traceable to national standards through certified calibration certificates issued by CNAS-accredited laboratories. For regulated environments, audit trails, user access controls, and electronic signature support can be enabled to align with FDA 21 CFR Part 11 and GLP/GMP documentation practices.
Software & Data Management
The Windows-based TFW TestSuite software provides ISO/IEC 17025-aligned test automation and reporting. It supports multiple control modes—including load-controlled, displacement-controlled, strain-controlled, and hold-mode sequences—with real-time PID parameter tuning. Users may configure multi-step test programs with conditional branching (e.g., “hold at 80% yield load for 60 s”), automatic yield point detection (0.2% offset method), and modulus calculation via linear regression over user-defined strain intervals. The software displays synchronized real-time plots of force–time, force–displacement, stress–strain, and extension–time; overlays up to eight curves for comparative analysis; and exports raw data in CSV, XML, and universal MDF4 formats. Reports comply with ASTM E2309 formatting guidelines and include metadata such as operator ID, environmental conditions (optional sensor integration), calibration dates, and uncertainty statements. Data integrity safeguards include write-protected archives, versioned backups, and optional encrypted database storage.
Applications
- Mechanical qualification of aerospace aluminum alloys (e.g., 2024-T3, 7075-T6) per AMS 4027 and MIL-STD-810
- Tensile and compressive behavior mapping of thermoplastic composites (CFRP, GFRP) in automotive lightweighting R&D
- Adhesion strength evaluation of coated steel substrates using ASTM D4541 pull-off testing
- Creep and relaxation characterization of medical-grade silicone elastomers under ISO 5840-3
- Quality control of structural concrete cylinders (ASTM C39) and mortar prisms (ASTM C109)
- Validation of additive manufacturing build parameters through post-process tensile testing of Ti-6Al-4V LPBF samples
- Evaluation of packaging film peel strength (ASTM F904), seal integrity (ASTM F88), and puncture resistance (ASTM F1306)
FAQ
What standards does the TFW-310 support out-of-the-box?
The system includes preconfigured test methods for ASTM E8/E9/E21, ISO 6892-1/15630-1, GB/T 228.1, and DIN 50145, with additional templates available upon request.
Can the machine perform cyclic or fatigue testing?
No—the TFW-310 is designed exclusively for static and quasi-static tests. For dynamic or high-cycle fatigue applications, consider Tuofeng’s dedicated electrodynamic fatigue testing systems (e.g., TF-FS series).
Is third-party calibration certification included?
Yes—a full calibration certificate compliant with ISO/IEC 17025 is provided at shipment, covering force, displacement, and strain channels, with traceability to NIM (National Institute of Metrology, China).
How is software validation handled for regulated industries?
TFW TestSuite supports IQ/OQ documentation packages and configurable audit trail logging. Validation assistance and 21 CFR Part 11 readiness assessments are available under separate service agreement.
What is the warranty and service coverage?
Standard coverage includes 24 months parts-and-labor warranty, remote diagnostics, and lifetime firmware updates. On-site service contracts with SLA-governed response times are available globally.
