TuoFeng TFL-01 Microcomputer-Controlled Single-Column Electronic Tensile Testing Machine

Overview

The TuoFeng TFL-01 is a precision-engineered single-column electronic tensile testing machine designed for routine and R&D-grade mechanical property evaluation of low-force materials. Operating on the fundamental principle of uniaxial force application under controlled displacement or load control, it conforms to standardized quasi-static tensile, peel, tear, and bond strength measurement protocols defined in ISO 527, ASTM D882 (plastic films), ASTM D3330 (adhesive tape peel), ISO 11339 (peel resistance), and GB/T 1040 series. Its compact architecture integrates a high-resolution load cell, servo-controlled crosshead drive, and optical encoder-based displacement feedback—enabling reproducible force-displacement data acquisition across compliant thin-film, fiber, foil, and adhesive substrates. The system is calibrated per ISO 7500-1 Class 0.5 requirements and supports traceable verification via internal calibration routines and external standard weights.

Key Features

• Single-column rigid frame with aluminum alloy extrusion housing and precision-ground lead screw, optimized for stability during sub-newton to 2-kN loading
• High-sensitivity load cell (1–2000 N range) with ±0.5% full-scale accuracy and 1/300,000 internal resolution—no range switching required
• Crosshead travel of 700 mm (extendable upon request), driven by a 400 W AC servo motor with 0.01–500 mm/min infinitely variable speed control
• Displacement measurement via quadrature optical encoder, delivering 0.0001 mm resolution and ±0.5% linearity over full stroke
• Dual safety architecture: hardware-based electronic limit switches + software-defined overload cutoff at 110% of maximum rated load
• Intelligent crosshead control with three-speed jog mode (fast/medium/slow), programmable return-to-start, and emergency stop integration
• Modular fixture interface compatible with pneumatic, wedge, and custom-designed grips for film clamping, 180° peel, trouser tear, and loop tack configurations

Sample Compatibility & Compliance

The TFL-01 is validated for use with specimens ≤10 mm thick and ≤50 mm wide, including biaxially oriented polypropylene (BOPP), polyester (PET), polyethylene (PE), aluminum foil, metallized films, nonwovens, pressure-sensitive adhesives, laminated packaging structures, and biomedical polymer strips. It meets mechanical testing prerequisites for ISO 1798 (flexible cellular polymeric materials), ASTM F88 (seal strength of flexible barrier materials), and USP <1207> (package integrity). All force and displacement outputs are traceable to national metrological standards. System validation documentation supports GLP-compliant environments, and audit trails comply with FDA 21 CFR Part 11 requirements when configured with user access controls and electronic signature modules.

Software & Data Management

The Windows-based TensilePro™ software (v5.x) provides full test method configuration, real-time visualization, and post-processing in accordance with ISO 1798 Annex B and ASTM E4. It supports multi-language UI (English, Simplified/Traditional Chinese), customizable unit systems (N, lbf, MPa, psi, % strain), and synchronized dual-axis plotting (e.g., stress–strain, load–displacement, peel force–distance). Built-in calculation engines automatically derive tensile strength, yield point, modulus (secant/tangent), elongation at break, peel adhesion energy (J/m²), and tear propagation resistance (N/mm). Raw data exports to CSV, XML, and PDF report formats include metadata such as operator ID, environmental conditions (optional sensor input), calibration date, and instrument serial number. Software updates are delivered remotely with version-controlled changelogs and backward-compatible data file handling.

Applications

• Quantitative assessment of tensile modulus and breaking elongation in cast and blown plastic films per ASTM D882
• Peel strength characterization of heat-sealed pouches, cold seal coatings, and medical device packaging per ASTM F904
• Tear resistance evaluation using Elmendorf or trouser tear geometries for flexible packaging substrates
• Bond strength testing of laminated layers in multilayer food packaging (e.g., PET/Alu/PE structures)
• Quality control of thin-gauge metal foils and conductive polymer films used in flexible electronics
• Material comparison studies in academic polymer science labs requiring high repeatability at low-load regimes

FAQ

What standards does the TFL-01 support out-of-the-box?
It includes preloaded test methods for ASTM D882, ISO 527-3, GB/T 1040.3, and ASTM D3330—with editable parameters for strain rate, preload, and failure criteria.
Can the system be integrated into an automated production line?
Yes—RS-232, USB, and optional Ethernet interfaces enable SCADA-level communication; digital I/O ports support external start/stop and pass/fail signaling.
Is third-party calibration certification available?
TuoFeng provides ISO/IEC 17025-accredited calibration certificates (traceable to NIM, China) upon request, with annual recalibration reminders embedded in the software.
How is data integrity ensured during long-duration creep tests?
The firmware implements cyclic memory buffering and automatic timestamped backup every 5 seconds; power-loss recovery resumes from last saved state without data corruption.
Does the machine support extensometer attachment for true strain measurement?
Yes—the base unit includes a standardized DIN 51221-compliant extensometer port; contact and non-contact (video-based) options are available as field-upgradable modules.
