Tuofeng TFW-118 Microcomputer-Controlled Electromechanical Universal Tensile Testing Machine

Overview

The Tuofeng TFW-118 is a high-precision, microcomputer-controlled electromechanical universal tensile testing machine engineered for rigorous static mechanical property evaluation of metallic, polymeric, composite, and elastomeric materials. Based on the fundamental principle of controlled uniaxial force application via servo-driven ball-screw actuation, the system delivers traceable, repeatable load-displacement data under standardized quasi-static conditions. Its architecture adheres to international metrological frameworks—including ISO 7500-1 (Class 0.5 accuracy), ASTM E4 (verification of force-measuring instruments), and GB/T 16491–2008—ensuring data integrity across R&D, quality control, and regulatory submission workflows. Designed for integration into GLP-compliant laboratories and ISO/IEC 17025-accredited testing facilities, the TFW-118 supports full-cycle mechanical characterization including tensile, compression, flexure, shear, tear, peel, and puncture testing—when paired with application-specific fixtures.

Key Features

• High-stiffness dual-column frame with precision-ground ball-screw transmission system, delivering smooth, backlash-free motion and long-term dimensional stability.
• Imported AC servo motor coupled with worm-gear reduction gearbox ensures precise speed control across the full range of 0.001–500 mm/min (infinitely variable, no gear shifting required).
• Force transducer calibrated to ±0.5% of reading over 0.2–100% FS, with internal 500,000-count A/D resolution and no range switching—maintaining consistent sensitivity across low-force and high-load regimes.
• Optical encoder-based displacement measurement with 0.001 mm resolution and ±0.005% accuracy; optional extensometer integration (contact or non-contact) for strain-controlled protocols per ASTM E83 or ISO 9513.
• Dual-speed motorized crosshead adjustment (fast/slow modes) with programmable return-to-start function and emergency stop, electronic limit switches, and overload protection (>110% FS).
• Modular fixture interface accommodating standardized grips (pneumatic, wedge, vise), bending jigs, peel fixtures, and custom tooling per specimen geometry and industry standard requirements.

Sample Compatibility & Compliance

The TFW-118 accommodates specimens up to 1000 mm stroke and 600 mm effective test width (expandable upon request), supporting flat, round, tubular, and irregular geometries from sub-millimeter wires to structural composites. It fully implements test methodologies defined in ASTM D638 (tensile plastics), ASTM D412 (vulcanized rubber), ISO 527, ISO 6892-1 (metal tensile), ISO 179 (impact-modified polymers), GB/T 228.1, and JIS Z 2241. All hardware and firmware comply with GB/T 16491–2008 (Chinese national standard for electronic universal testers) and JJG 475–2008 (verification regulation). Calibration certificates are traceable to NIM (National Institute of Metrology, China) or equivalent national metrology institutes under CIPM MRA mutual recognition arrangements.

Software & Data Management

The Windows-based TFW-TestSuite software provides multi-mode control (load-, displacement-, or time-targeted), real-time plotting of up to four synchronized curves (e.g., stress–strain, load–time, displacement–time), and automated calculation of mechanical parameters per ISO 527-2, ASTM D638, and EN 10002-1. Units are freely convertible (N/kN/lbf, mm/in, MPa/psi), and language support includes English, Simplified Chinese, and Traditional Chinese. Data export conforms to ASTM E1434 (standard format for material test data) and supports CSV, PDF, and XML outputs. Audit trail functionality records operator ID, timestamp, method version, calibration status, and raw data checksums—enabling compliance with FDA 21 CFR Part 11 (electronic records/signatures) and EU Annex 11 when deployed in regulated environments. Software updates are provided free of charge for the instrument’s operational lifetime.

Applications

• Material qualification in aerospace composites (carbon fiber laminates, honeycomb cores) per Boeing BMS 7-112 and Airbus AITM standards.
• QC verification of polymer extrusions, injection-molded parts, and elastomeric seals in automotive Tier-1 supply chains.
• Mechanical validation of medical device components (catheter tubing, suture anchors, orthopedic implants) aligned with ISO 14243 and ASTM F2118.
• Research-grade tensile fatigue pre-screening and creep behavior assessment in academic and industrial polymer labs.
• Third-party certification testing for construction materials (rebar, geotextiles, adhesives) under GB/T standards and CE marking directives.
• Wire-and-cable mechanical integrity testing per IEC 60811 and UL 1581.

FAQ

What standards does the TFW-118 support out-of-the-box?

The system ships with pre-configured test methods for ASTM D638, ISO 527, GB/T 228.1, and ISO 6892-1, with additional templates available via software update.
Can the machine perform cyclic loading or fatigue tests?

The base configuration supports quasi-static monotonic loading only; high-cycle fatigue capability requires optional hydraulic or electrodynamic actuator upgrade and dedicated controller.
Is third-party calibration documentation included?

Yes—a factory calibration certificate traceable to NIM is supplied; on-site ISO/IEC 17025 calibration services are available upon request.
What is the warranty coverage and service response time?

Standard warranty is 24 months parts-and-labor; technical support is available 24/5, with on-site service dispatch within 72 business hours in major Asia-Pacific metropolitan areas.
Does the software support LIMS integration?

Yes—via configurable ODBC drivers and RESTful API endpoints for bidirectional data exchange with common LIMS platforms (e.g., LabVantage, Thermo Fisher SampleManager).
