Tuofeng TFL-36S Computer-Controlled Electronic Tensile Testing Machine

Overview

The Tuofeng TFL-36S is a microprocessor-driven, computer-controlled electronic tensile testing machine engineered for precision mechanical property evaluation of thin films, foils, fibers, polymers, adhesives, and other low-to-medium strength materials. It operates on the fundamental principle of uniaxial force application under controlled displacement or load rate, enabling quantification of tensile strength, yield point, elongation at break, modulus of elasticity, tear resistance, peel adhesion, and puncture performance. Designed to meet the rigorous repeatability and traceability requirements of QC laboratories and R&D facilities, the system delivers high reproducibility across diverse sample geometries — from sub-millimeter polymer films to 25-mm-wide metal strips — with full compliance to international standard test methods.

Key Features

• High-resolution force measurement system calibrated to ±0.5% of reading across 0.4–100% of full scale (5 kN), eliminating range-switching artifacts and ensuring consistent accuracy throughout the entire load spectrum.
• Optically encoded crosshead positioning with ±0.5% displacement linearity and 700 mm standard travel — extendable upon request — supporting both short-gauge-thin-film tests and long-stroke deformation analysis.
• Infinitely variable speed control (0.01–500 mm/min) enables precise replication of standardized strain rates per ASTM D882 (plastic films), ISO 527-3 (thin plastics), or GB/T 1040.3 (polymer tensile testing).
• Dual-mode operation: closed-loop load control for creep/stress-relaxation protocols and displacement control for tensile, peel, and tear testing — configurable via intuitive software interface.
• Integrated safety architecture featuring hardware-based emergency stop, programmable electronic limit switches, and automatic overload cutoff at 110% of maximum capacity.
• Modular fixture mounting platform compatible with pneumatic, wedge, roller, and custom-designed grips — including film clamps with serrated jaws and low-force peel fixtures meeting ASTM D3330 specifications.

Sample Compatibility & Compliance

The TFL-36S accommodates specimens ranging from 0.012 mm thick polymer films to 1.5 mm aluminum foil, textile yarns (denier ≥50), laminated packaging substrates, pressure-sensitive adhesives, and biomedical hydrogels. Its design supports standard specimen geometries per ISO 527-3 (Type 1A dumbbell), ASTM D882 (gauge length 50–200 mm), and GB/T 2792 (peel testing). All mechanical and software functions are validated against ISO/IEC 17025:2017 calibration traceability requirements. The system supports audit-ready documentation workflows aligned with GLP and GMP environments, including user access logs, calibration history tracking, and instrument parameter versioning.

Software & Data Management

The Windows-based testing software (compatible with Windows 10/11, 64-bit) provides full compliance with FDA 21 CFR Part 11 through optional electronic signature modules, role-based user permissions, and immutable audit trails. It supports multi-language UI (English, Simplified/Traditional Chinese), customizable unit systems (N, kN, lbf, MPa, psi, %, mm, inch), and real-time plotting of up to four synchronized curves: load–time, load–displacement, stress–strain, and extension–time. Advanced analysis tools include automatic yield point detection (0.2% offset method), tangent modulus calculation, area-under-curve integration for toughness estimation, and batch statistical reporting (mean, SD, CV%, min/max). Raw data exports to CSV, Excel, and XML formats; test reports comply with ISO 14289-1 (PDF/A-1a) archival standards.

Applications

• Thin-film mechanical characterization for flexible electronics, barrier coatings, and pharmaceutical blister packaging.
• Quality assurance of metallized PET, aluminum foil, and copper-clad laminates in battery and semiconductor supply chains.
• Adhesive bond strength validation per ASTM D1876 (T-peel), D903 (peel), and D6252 (loop tack).
• Biodegradable polymer film development under ISO 14855-2 accelerated composting conditions.
• Textile fiber tensile profiling for automotive interior nonwovens and medical gauze substrates.
• Regulatory submission support for USP mechanical testing of transdermal patch backing layers.

FAQ

What standards does the TFL-36S support out-of-the-box?
The system includes preconfigured test templates for ASTM D882, ISO 527-3, GB/T 1040.3, ISO 1184, and JIS Z2241, with editable parameters for strain rate, hold time, and failure criteria.
Can the machine perform cyclic loading or fatigue tests?
Yes — with optional waveform generator module, it supports sinusoidal, triangular, and trapezoidal load/displacement profiles up to 5 Hz, suitable for low-cycle fatigue assessment of elastomeric films.
Is third-party calibration certification available?
Tuofeng provides NIST-traceable factory calibration certificates; users may also engage ISO/IEC 17025-accredited external labs for periodic verification.
How is data integrity ensured during long-duration tests?
The controller employs dual-buffered memory with auto-recovery on power interruption, and all sensor readings are timestamped with microsecond resolution using internal RTC synchronization.
Does the software support LIMS integration?
Yes — via HL7 v2.x and ASTM E1384-compliant API, enabling bidirectional data exchange with major laboratory information management systems including LabVantage and Thermo Fisher SampleManager.
