Overview
The Tofeng TFL-05 Digital LCD Display Tensile Testing Machine is a single-column, microprocessor-controlled electromechanical testing system engineered for precision mechanical property evaluation of low-to-medium strength materials. It operates on the fundamental principle of controlled uniaxial force application—measuring tensile, peel, tear, and bond strength responses under standardized displacement or load control. Designed for laboratories and QC environments where repeatability, traceability, and regulatory alignment are essential, the TFL-05 delivers consistent force measurement across its full 1–5000 N range with an accuracy of ±0.5% of reading—compliant with ISO 7500-1 Class 0.5 requirements for static force verification. Its robust single-column architecture supports stable specimen alignment and minimizes lateral deflection during high-sensitivity tests on fine wires, thin films, fibers, and laminated packaging substrates.
Key Features
- Single-column rigid frame with precision-ground lead screw and high-resolution stepper motor drive for smooth, backlash-free crosshead motion.
- Digital LCD display interface with real-time visualization of load (N), displacement (mm), and test speed (mm/min)—enabling standalone operation without PC dependency.
- Integrated optical encoder-based displacement measurement system with 0.0001 mm resolution and ±0.5% displacement accuracy per ISO 6892-1 Annex B.
- Load cell calibrated to 0.5% accuracy across 0.4–100% of full scale (FS), supporting both internal and external calibration traceable to national metrology institutes.
- Three-speed programmable crosshead movement (fast/medium/slow) with manual jog control and automatic return-to-start functionality post-test.
- Dual safety architecture: electronic limit switches at upper/lower travel boundaries plus emergency stop button compliant with IEC 60204-1 safety standards.
- Modular fixture mounting platform accommodating custom grips—including pneumatic, wedge, and pin-type configurations—for metals, polymers, textiles, adhesives, and biomedical films.
Sample Compatibility & Compliance
The TFL-05 is validated for use with specimens conforming to standard geometries defined in ASTM D638 (plastics), ASTM D882 (thin plastic sheeting), ISO 527 (tensile properties of plastics), ISO 1974 (tear resistance of paper), and GB/T 228.1 (metallic materials). Its 700 mm vertical travel accommodates extended gauge lengths required for elongation-sensitive materials such as elastomers and hydrogels. The system supports compliance with GLP and GMP documentation workflows when paired with optional audit-trail-enabled software modules. All mechanical components meet RoHS Directive 2011/65/EU restrictions on hazardous substances, and electrical design conforms to CE marking requirements under the Machinery Directive 2006/42/EC.
Software & Data Management
The Windows-based Tofeng TestSuite software (XP/Vista/7/10 compatible) provides full test method configuration and data analysis capabilities. It supports multi-language UI switching (English, Simplified Chinese, Traditional Chinese), customizable unit systems (N/kN, MPa/psi, mm/in), and dynamic curve overlays for comparative material analysis. Real-time plotting includes load–time, load–displacement, stress–strain, and displacement–time graphs—with automatic calculation of tensile strength, yield point, modulus, elongation at break, peel adhesion, and tear energy. Data export is available in CSV, XLSX, and PDF formats; all test files include embedded metadata (operator ID, timestamp, environmental conditions, calibration certificate ID). Software updates are provided free of charge for the instrument’s operational lifetime, ensuring continued compatibility with evolving OS security protocols and regulatory reporting formats.
Applications
- Mechanical characterization of metallic fine wires (e.g., Cu, NiTi, stainless steel <0.5 mm diameter) per ASTM E8/E21.
- Peel strength assessment of pressure-sensitive adhesives on flexible packaging substrates (ASTM D903, ISO 8510-2).
- Tensile testing of nonwoven fabrics, surgical gauze, and wound dressings per ISO 9073-3.
- Quality control of polymer films (PET, PP, PE) for packaging integrity and seal strength validation (ASTM F88, ISO 11607-2).
- Testing of paperboard, corrugated fiberboard, and label stock per TAPPI T494 and ISO 3781.
- Research-grade evaluation of biodegradable hydrogels and tissue-engineered scaffolds under hydrated conditions (custom environmental chamber integration supported).
FAQ
What standards does the TFL-05 support out-of-the-box?
The machine includes preconfigured test methods for ASTM D638, ISO 527, GB/T 228.1, and JIS Z 2241—accessible via the LCD menu or software wizard.
Can the system be integrated into a LIMS or ERP environment?
Yes—via optional RS232/USB virtual COM port output and structured CSV export, enabling direct ingestion into laboratory information management systems compliant with ASTM E1482 or ISO/IEC 17025 data integrity requirements.
Is third-party calibration certification available?
Tofeng provides factory calibration certificates traceable to CNAS-accredited labs; users may request ISO/IEC 17025-certified calibration reports with uncertainty budgets upon order.
What is the warranty coverage and service response time?
Standard 24-month parts-and-labor warranty; on-site technical support available within 5 business days in major Asia-Pacific industrial zones.
Does the system meet FDA 21 CFR Part 11 requirements for electronic records?
The base software does not include Part 11 features; however, the optional Tofeng SecureTest module adds electronic signatures, audit trails, and role-based access control—validated for pharmaceutical and medical device QA/QC use.
