Overview
The Tuofeng TFL-27S is a precision-engineered computer-controlled electronic tensile testing machine designed for static mechanical property evaluation of low-to-medium strength materials. It operates on the principle of controlled uniaxial force application via a servo-motor-driven crosshead, with real-time acquisition of load, displacement, and time data to derive fundamental mechanical parameters—including tensile strength, yield strength, elongation at break, modulus of elasticity, tear strength, peel adhesion, and bond strength. Its modular architecture supports standardized test protocols across metallurgy, polymer science, textiles, packaging, electronics interconnects, and biomedical materials research. The system complies with international mechanical testing standards including ASTM D638 (plastics), ISO 527 (tensile properties of plastics), GB/T 1040 (Chinese national standard for plastic tensile testing), DIN 53455 (adhesive peel testing), and JIS K 7113 (Japanese industrial standard for polymer tensile behavior). Designed for laboratory and quality control environments, the TFL-27S delivers high reproducibility, traceable calibration paths, and robust mechanical stability under continuous operation.
Key Features
- High-resolution force measurement system with ±0.5% accuracy over 0.4–100% of full scale (5 kN), eliminating range-switching artifacts and ensuring linearity across dynamic loading conditions.
- Optical encoder-based displacement sensing with ±0.5% accuracy and 700 mm standard travel—extendable upon request—enabling precise strain quantification in both short-gauge and large-deformation tests.
- Infinitely variable speed control from 0.01 to 500 mm/min, supporting quasi-static to rapid-rate mechanical characterization required by ISO 6892-1 (metallic materials) and ASTM D882 (thin plastic sheeting).
- Integrated safety architecture featuring dual electronic limit switches, hardware-triggered emergency stop, and automatic overload cutoff at ≥110% of rated capacity—fully compliant with EN ISO 12100 (risk assessment for machinery).
- Modular fixture interface accommodating custom-designed grips for wires, foils, films, fibers, laminates, and adhesive substrates—including pneumatic, wedge, and pin-type configurations.
- Stiff, cast-iron frame with precision-ground guideways and low-backlash ball screws ensures minimal deflection (<0.02 mm under full load), critical for accurate stress–strain curve reconstruction.
Sample Compatibility & Compliance
The TFL-27S accommodates specimens ranging from ultra-thin polymer films (≥12 µm) and fine metallic wires (diameter < 0.1 mm) to rigid composite laminates and flexible packaging structures. Standard test geometries include dog-bone, straight-strip, and loop configurations per ASTM D638 Type I–V and ISO 527-2. For textile yarns and filaments, optional fiber-specific clamping kits maintain uniform grip pressure without slippage or premature rupture. All test methods are pre-configured to align with regulatory frameworks: FDA-regulated medical device packaging validation (ASTM F88 peel), ISO 10993-12 biocompatibility mechanical testing, and GLP-compliant QC workflows requiring audit-ready metadata capture. Calibration certificates conform to ISO/IEC 17025 and are traceable to NIM (National Institute of Metrology, China) standards.
Software & Data Management
The embedded Windows-based control software supports multi-language UI (English, Simplified/Traditional Chinese), SI/imperial unit switching, and six real-time plotting modes: Load–Time, Load–Displacement, Displacement–Time, Stress–Strain, Load–Extension, and custom user-defined axes. Data acquisition occurs at up to 1 kHz sampling rate, with 24-bit ADC resolution and internal storage of ≥10,000 test records. Each test file embeds metadata—operator ID, environmental conditions (optional sensor integration), calibration timestamp, and instrument firmware version—to satisfy 21 CFR Part 11 requirements for electronic records and signatures when paired with optional audit-trail and user-access-level modules. Export formats include CSV, XML, PDF reports (with configurable templates), and native .tdf binary for third-party analysis (e.g., MATLAB, OriginLab). Software updates are delivered remotely with version-controlled release notes and backward-compatible data migration.
Applications
- Mechanical qualification of copper/aluminum wire bonds in semiconductor packaging per JEDEC JESD22-B103.
- Tensile and peel performance verification of pressure-sensitive adhesives used in medical transdermal patches (ISO 2555, ASTM D3330).
- Quality assurance of food-grade laminated pouches (e.g., PET/AL/PE) for seal integrity and burst resistance (ASTM F1140/F2054).
- Research-grade characterization of electrospun nanofibers and hydrogel thin films under controlled humidity environments.
- QC screening of textile yarn tenacity and elongation per ISO 2062, including conditioned testing at 65% RH / 20°C.
- Validation of 3D-printed polymer parts (ABS, PLA, TPU) against ISO/ASTM 52921 mechanical test guidelines.
FAQ
What standards does the TFL-27S support out-of-the-box?
Pre-loaded test methods cover ASTM D638, ISO 527, GB/T 1040, DIN 53455, JIS K 7113, and ASTM D882—with customizable parameter sets for strain rate, preload, and hold duration.
Can the system be integrated into an existing LIMS or MES environment?
Yes—via TCP/IP API (RESTful JSON endpoints) and optional OPC UA server module for bidirectional data exchange with LabWare, Thermo Fisher SampleManager, or Siemens Opcenter.
Is third-party calibration certification available?
Tuofeng provides factory calibration with NIM-traceable certificates; accredited third-party calibration (e.g., SGS, TÜV Rheinland) can be arranged upon order.
Does the software meet FDA 21 CFR Part 11 requirements?
Base software supports electronic signatures and audit trails; full Part 11 compliance requires activation of the optional Security & Compliance Pack (user role management, encrypted log files, electronic signature workflow).
What is the warranty and service coverage?
Standard 24-month parts-and-labor warranty; extended service plans include remote diagnostics, annual preventive maintenance, and priority spare-part dispatch.
