Overview
The Tuofeng TFL-02 Desktop Electronic Tensile Testing Machine is a precision-engineered single-column universal tester designed for routine mechanical property evaluation of low-force specimens in R&D laboratories, QC departments, and academic institutions. Based on servo-controlled electromechanical actuation and high-fidelity load cell transduction, the system applies controlled uniaxial tension or compression to quantify fundamental material responses—including tensile strength, yield point, elongation at break, peel adhesion, tear resistance, and bond integrity. Its compact footprint (460 × 460 × 1500 mm) and 120 kg mass ensure stable operation without floor anchoring, while the 700 mm vertical travel accommodates standard specimen geometries used in wire, foil, film, fiber, adhesive tape, and thin packaging substrate testing. The machine complies with core mechanical testing principles defined in ISO 6892-1, ASTM E8/E21, GB/T 228.1, and JIS Z 2241, supporting both force-controlled and displacement-controlled test modes.
Key Features
- Single-column rigid frame with reinforced aluminum alloy housing and precision-ground lead screw drive for minimal deflection and long-term repeatability.
- High-resolution load measurement via calibrated S-type load cell (rated capacity: 100 N), delivering ±0.5% accuracy across 0.4–100% of full scale—no range switching required.
- Optical encoder-based displacement sensing with 0.0001 mm resolution and ±0.5% linearity over full stroke (700 mm).
- Three-speed motorized crosshead control (fast/medium/slow) with programmable return-to-start function; supports manual jog operation for precise specimen alignment.
- Integrated electronic limit switches and emergency stop circuitry compliant with IEC 60204-1 safety standards.
- Overload protection triggers automatically at 110% of maximum rated load (110 N), halting motion and preserving sensor integrity.
- Modular fixture interface compatible with pneumatic, wedge-grip, peel, and custom-designed clamping solutions for diverse sample geometries.
Sample Compatibility & Compliance
The TFL-02 is validated for testing specimens up to 5000 N (5 kN) static load capacity, with optimal performance in the 1–500 N range typical of fine wires (diameter ≤ 0.5 mm), polymer films (< 250 µm), nonwovens, medical tubing, pressure-sensitive adhesives, laminated packaging, and micro-electronic interconnects. It supports standardized test configurations per ISO 527-3 (plastics—films), ASTM D882 (thin plastic sheeting), ASTM D3330 (adhesive tape peel), and GB/T 1040.3 (plastics—tensile properties of films and sheets). All hardware and firmware are designed to meet GLP documentation requirements, including audit-trail-capable test data logging and user-accessible calibration certificate templates traceable to national metrology institutes.
Software & Data Management
The Windows-based TensilePro™ software (v3.2+) provides full compliance with FDA 21 CFR Part 11 for electronic records and signatures when configured with user authentication and audit trail modules. It supports multi-language UI (English, Simplified/Traditional Chinese), customizable unit systems (N, lbf, MPa, psi, %, mm, inch), and real-time plotting of up to four synchronized curves: load–time, load–displacement, stress–strain, and extension–time. Automated calculations include tensile strength, Young’s modulus, yield offset (0.2%), elongation at break, peel strength (180°/90°), and tear energy (Elmendorf-type equivalent). Raw data exports to CSV, Excel, and PDF formats; batch analysis tools enable statistical comparison across up to 99 specimens per report. Software updates are delivered via secure HTTPS portal with version-controlled release notes.
Applications
- Mechanical qualification of metallic microwires and shape-memory alloys in microfabrication labs.
- Quality assurance of lithium-ion battery separator films under dry/wet conditions.
- Adhesion strength validation of medical device bonding layers (e.g., silicone–polyimide interfaces).
- Tensile behavior characterization of biodegradable sutures and hydrogel membranes.
- Peel and tack performance assessment of pressure-sensitive labels and protective films.
- Educational use in materials science curricula for hands-on demonstration of Hooke’s law, necking, and fracture mechanics fundamentals.
FAQ
What standards does the TFL-02 support out-of-the-box?
The system includes pre-configured test methods for ISO 6892-1, ASTM E8, GB/T 228.1, and JIS Z 2241, with additional method templates available upon request.
Can the TFL-02 be upgraded to higher load capacities?
No—the TFL-02 is mechanically and electronically optimized for ≤100 N nominal load; higher-capacity variants (TFL-05S, TFL-1S) require separate frame and load cell assemblies.
Is third-party calibration certification included?
Yes—a factory-issued NIST-traceable calibration certificate covering force and displacement axes is provided with each unit.
Does the software support automated pass/fail criteria?
Yes—users can define upper/lower limits for any calculated parameter (e.g., tensile strength ≥ 35 MPa); results are color-coded and flagged in summary reports.
What maintenance is required for long-term accuracy?
Annual verification of load cell linearity and encoder resolution is recommended; no routine lubrication or mechanical adjustment is needed due to sealed lead screw and brushless DC motor design.
