Tuofeng TFL-08 Desktop Microcomputer-Controlled Electronic Tensile Testing Machine

Overview

The Tuofeng TFL-08 Desktop Microcomputer-Controlled Electronic Tensile Testing Machine is a precision-engineered single-column electromechanical system designed for routine mechanical property evaluation of low-force specimens in R&D laboratories, QC environments, and academic settings. Operating on the fundamental principle of controlled uniaxial loading—where a motor-driven crosshead applies calibrated tensile, peel, tear, or flexural force to a specimen while high-fidelity transducers record real-time load and displacement—the TFL-08 delivers repeatable, traceable mechanical data compliant with standardized test methodologies. Its compact footprint (460 × 460 × 1500 mm) and 120 kg mass ensure stability without requiring floor anchoring, making it ideal for benchtop deployment in regulated spaces such as ISO 17025-accredited labs or GMP-aligned packaging validation suites.

Key Features

• Single-column rigid frame constructed from high-strength aluminum alloy and hardened steel components, optimized for minimal deflection under load and long-term dimensional stability.
• High-resolution load cell with full-scale capacity of 100 N and accuracy certified to ±0.5% of reading across 0.4–100% of full scale—meeting ASTM E4 and ISO 7500-1 Class 0.5 requirements.
• Precision ball-screw-driven crosshead actuation system with brushless DC servo motor (220 V, 50 Hz, 400 W), enabling smooth, silent operation across a continuous speed range of 0.01–500 mm/min.
• Optical encoder-based displacement measurement system with 0.0001 mm resolution and ±0.5% linearity error, synchronized with load acquisition at up to 1 kHz sampling rate.
• Integrated electronic limit switches and emergency stop circuitry compliant with IEC 61800-5-2 functional safety standards; automatic overload cutoff at 110% of maximum rated load.
• Three-speed programmable table movement (fast/medium/slow) with manual jog capability and fully configurable return-to-start logic—supporting both automatic post-test retraction and operator-initiated positioning.

Sample Compatibility & Compliance

The TFL-08 accommodates specimens ranging from ultra-thin metallic foils (e.g., Cu, Al < 25 µm) and fine-diameter wires (< 0.5 mm) to polymeric films, adhesive tapes, medical tubing, paperboard substrates, and biodegradable packaging laminates. Standardized grips—including pneumatic, wedge, and roller-type configurations—are available for customization per material geometry and failure mode. The system supports testing protocols defined in GB/T 228.1, ISO 527-1, ASTM D882 (thin plastics), ASTM D638 (tensile bars), ASTM D903 (peel), ASTM D1876 (T-peel), ISO 11339 (adhesive strength), and JIS Z 1522 (paper tensile). All hardware and firmware comply with CE marking directives (2006/42/EC Machinery Directive, 2014/30/EU EMC Directive), and software architecture supports audit-ready operation under GLP/GMP conditions.

Software & Data Management

The embedded Windows XP-compatible control and analysis software provides full modal control—including constant-rate-of-extension (CRE), constant-load, constant-displacement, and dwell-hold modes—with real-time visualization of up to four simultaneous plots (e.g., force–time, stress–strain, displacement–time, force–extension). Units are freely convertible between SI, imperial, and metric systems (N, lbf, MPa, psi, mm, inch, % elongation). Raw data export is supported in CSV, TXT, and XLS formats; graphical reports include customizable headers, pass/fail thresholds, statistical summaries (mean, min, max, CV%), and overlaid comparative curves for batch analysis. The software implements role-based user access control, electronic signature support, and full audit trail logging—fully aligned with FDA 21 CFR Part 11 requirements when deployed with validated IT infrastructure.

Applications

• Mechanical characterization of thin-film electronics substrates during roll-to-roll manufacturing process development.
• Peel strength verification of pressure-sensitive adhesives used in medical device assembly and pharmaceutical blister packaging.
• Tensile modulus and yield point determination for hydrogel-based wound dressings per ISO 10993-10 biocompatibility guidance.
• Quality conformance testing of food-grade laminated pouch seals under accelerated aging conditions.
• Evaluation of fiber-matrix interfacial adhesion in natural fiber-reinforced composites (e.g., flax/PLA).
• Calibration and validation of micro-force sensors and MEMS-based transducers using reference specimens with certified mechanical properties.

FAQ

What is the maximum specimen thickness the TFL-08 can accommodate?
Standard configuration supports specimens up to 45 mm in height between grips; extended-height columns and custom grip assemblies are available upon request.
Does the system support extensometer integration for strain measurement?
Yes—both clip-on and non-contact video extensometers (with 10 µm resolution and 800 mm gauge length) can be integrated via analog/digital I/O ports and calibrated within the software environment.
Is the software compatible with modern Windows OS versions (e.g., Windows 10/11)?
While originally developed for Windows XP, the software has been validated for operation on Windows 10 (64-bit) through virtualization or updated runtime libraries; migration support and documentation are provided under Tuofeng’s lifetime service agreement.
Can test methods be exported and shared across multiple instruments?
Yes—test profiles (.tfl files) contain all method parameters, calibration coefficients, and reporting templates, and are fully portable between TFL-series machines running identical firmware revisions.
What documentation is supplied for regulatory compliance purposes?
Each unit ships with Factory Calibration Certificate (traceable to NIM China), Declaration of Conformity (CE), Installation Qualification (IQ) checklist, and User Requirements Specification (URS) template—enabling straightforward Performance Qualification (PQ) execution in regulated environments.
