Tuofeng TFW-114 Electronic Servo Tensile Testing Machine

Overview

The Tuofeng TFW-114 Electronic Servo Tensile Testing Machine is a high-precision universal testing system engineered for static mechanical property evaluation of metallic, polymeric, composite, and ceramic materials under uniaxial loading conditions. Based on closed-loop servo-controlled electromechanical actuation, the system employs a precision ball-screw drive mechanism coupled with a high-torque imported servo motor and planetary gear reducer to deliver stable, repeatable force application across a wide speed range (0.001–500 mm/min). The machine operates in accordance with fundamental principles of stress–strain analysis—measuring applied load via calibrated load cells and axial displacement via high-resolution optical encoders—to determine mechanical parameters including tensile strength, yield strength, elongation at break, Young’s modulus, compressive strength, flexural modulus, shear strength, tear resistance, and peel adhesion. Its modular architecture supports interchangeable fixtures and extensometers, enabling standardized testing per ISO 6892-1, ASTM E8/E21, GB/T 228.1, DIN 50125, JIS Z 2241, and BS EN 10002-1.

Key Features

• High-stiffness dual-column frame with reinforced crosshead and precision-ground guide rails for minimal deflection during high-load testing (up to 200 kN)
• Full-scale force measurement range from 0.2% to 100% FS with ±0.5% accuracy, compliant with ISO 7500-1 Class 0.5 calibration requirements
• Displacement resolution of 0.001 mm, supported by optical encoder-based position feedback and real-time digital control
• Dual-speed motorized crosshead adjustment (fast/slow modes) with programmable return-to-start function and emergency stop circuitry
• Integrated safety systems: electronic travel limit switches, overload protection (auto-shutdown at >110% FS), and mechanical emergency brake
• Modular fixture interface compatible with wedge-action grips, compression platens, bend fixtures, shear adapters, and peel test jigs
• Optional extensometer support—including clip-on and non-contact video extensometry—for strain measurement per ASTM E83 or ISO 9513

Sample Compatibility & Compliance

The TFW-114 accommodates specimens ranging from thin films (≥0.1 mm thickness) to structural steel coupons (up to 60 mm width × 25 mm thickness), with effective test width configurable up to 600 mm. It supports standard specimen geometries defined in ISO 527, ASTM D638, ASTM D3039, ISO 178, and GB/T 1040. All hardware and firmware comply with electromagnetic compatibility (EMC) directives IEC 61326-1 and safety standard IEC 61000-6-2. Mechanical design conforms to GB/T 16491–2008 (Chinese national standard for electronic universal testing machines) and JJG 475–2008 (verification regulation for electronic universal testing machines). Calibration traceability is maintained to national metrological standards through factory-certified load cell and displacement sensor verification.

Software & Data Management

The Windows-based TFW-TestSuite software provides ISO/IEC 17025-aligned data acquisition and reporting functionality. It supports multiple control modes—including constant rate of extension (CRE), constant load ramping, hold-at-load, and displacement-controlled cycling—and enables simultaneous acquisition of load, displacement, and optional strain channels. Real-time plotting includes stress–strain, load–time, load–displacement, and strain–time curves, with overlay capability for comparative analysis of up to 16 datasets. Units are freely convertible between SI, imperial, and legacy systems (e.g., N/kN/lbf, mm/in, MPa/psi). Software features audit-trail logging, user-access levels (admin/operator/guest), electronic signature support, and export to CSV, PDF, and XML formats. The platform satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with password-protected user accounts and immutable event logs.

Applications

This system serves as a primary mechanical characterization tool in R&D laboratories and QC departments across aerospace (e.g., titanium alloy tensile validation per AMS 2300), automotive (composite bumper impact simulation, rubber bushing compression hysteresis), medical device manufacturing (suture tensile strength per ISO 10993-12), wire & cable (conductor elongation and jacket tear resistance per UL 1581), and construction materials (rebar yield verification per ASTM A615). It is routinely deployed for failure mode analysis, material qualification against procurement specifications, process parameter optimization (e.g., injection molding dwell time vs. part stiffness), and third-party certification testing accredited to ISO/IEC 17025.

FAQ

What international standards does the TFW-114 support out-of-the-box?
The system is pre-configured with test methods aligned to ISO 6892-1, ASTM E8, GB/T 228.1, and EN ISO 15630-1; additional standards can be implemented via custom method templates.
Can the machine perform cyclic or fatigue testing?
No—the TFW-114 is designed exclusively for quasi-static monotonic and controlled-rate tests; fatigue applications require dedicated servo-hydraulic or electrodynamic systems.
Is third-party calibration documentation included?
Yes—each unit ships with a factory calibration certificate traceable to CNAS-accredited reference standards, valid for 12 months from date of shipment.
What is the warranty coverage and service response time?
Tuofeng provides a 24-month parts-and-labor warranty; technical support is available globally via remote diagnostics, with on-site service dispatch within 5 business days for covered regions.
Does the software support LIMS integration?
Yes—TW-TestSuite offers ODBC-compliant database connectivity and RESTful API endpoints for bidirectional data exchange with laboratory information management systems.
