Tuofeng TFW-212 Computer-Controlled Tensile Testing Machine for Paper and Thin Materials

Overview

The Tuofeng TFW-212 is a precision-engineered, computer-controlled electromechanical tensile testing machine designed specifically for the mechanical characterization of low-to-medium strength planar and filamentous materials—including paper, paperboard, corrugated board, thin films, foils, nonwovens, adhesives, and fine wires. It operates on the fundamental principle of uniaxial static tensile loading, where controlled displacement of the crosshead induces axial force in a standardized specimen, enabling quantitative determination of tensile strength, elongation at break, Young’s modulus, yield point, and peel or tear resistance. The system conforms to internationally recognized test methodologies defined in ISO 1924 (paper and board), ASTM D828 (tensile properties of plastic film), ASTM D638 (plastics), and GB/T 1040 (general polymer tensile testing), ensuring data traceability and inter-laboratory comparability.

Key Features

• High-fidelity load measurement using a calibrated 5 kN load cell with accuracy of ±0.5% of reading across 0.4–100% of full scale—no range switching required.
• Optical encoder-based displacement sensing with resolution better than ±0.5% of reading over 700 mm travel, supporting both standard and extended-height configurations.
• Infinitely variable crosshead speed control from 0.01 to 500 mm/min, enabling precise strain-rate selection per material class and standard requirement.
• Dual-mode operation: manual jog control for fixture alignment and automated test execution with pre-programmed profiles.
• Integrated safety architecture including electronic end-limit detection, hardware emergency stop circuitry, and automatic overload cutoff at 110% of rated capacity.
• Modular gripping system compatible with pneumatic, wedge-action, and custom fixtures—optimized for brittle, ductile, or low-modulus specimens such as tissue paper, kraft liner, or pressure-sensitive tapes.

Sample Compatibility & Compliance

The TFW-212 accommodates specimens up to 100 mm wide and 700 mm gauge length, making it suitable for ISO 1924-2 (paper strip testing), ASTM D828 (film tensile), and JIS P8113 (Japanese paper standards). Its force range and resolution are optimized for materials with ultimate tensile strengths between 0.1 MPa (e.g., blotting paper) and 300 MPa (e.g., high-strength metallic foils). All mechanical and software functions support audit-ready compliance with GLP and GMP environments. Test sequences, parameter settings, and raw data outputs adhere to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), and optional 21 CFR Part 11-compliant user authentication and electronic signature modules are available upon request.

Software & Data Management

The Windows-based TensilePro™ software (v4.x) provides full test configuration, real-time visualization, and post-processing capabilities. It supports multiple control modes—including constant rate of extension (CRE), constant load ramping, and displacement-targeted hold phases—and enables simultaneous display of up to four synchronized curves: load vs. time, load vs. displacement, stress vs. strain, and extension vs. time. Units for force (N, kN, lbf), displacement (mm, in), and derived properties (MPa, psi, % elongation) are freely convertible. Each test automatically calculates and reports tensile strength, breaking force, elongation at break, modulus (secant or tangent), and energy to break. Raw ASCII and CSV exports ensure compatibility with LIMS and statistical analysis platforms (e.g., JMP, Minitab). Audit trails record operator ID, timestamp, parameter changes, and calibration events—retained for ≥36 months per internal QA policy.

Applications

• Quantitative evaluation of paper tensile strength (MD/CD), burst index, and folding endurance per ISO 1924 and TAPPI T494.
• Peel strength assessment of laminated packaging films and pressure-sensitive labels (ASTM D903, ASTM D3330).
• Mechanical screening of biodegradable films, hydrogels, and electrospun nanofibrous mats used in medical packaging.
• Quality assurance of aluminum foil, copper ribbon, and stainless-steel wire in electronics manufacturing.
• R&D validation of adhesive bond integrity in flexible printed circuits and battery tab welds.
• Teaching laboratories for materials science courses requiring hands-on demonstration of stress–strain behavior.

FAQ

What standards does the TFW-212 support out-of-the-box?
The system includes preloaded test methods for ISO 1924-2, ASTM D828, ASTM D638, GB/T 1040.4, and JIS P8113. Custom method templates can be built via the software’s scripting interface.
Is calibration documentation included with shipment?
Yes—each unit ships with a factory calibration certificate traceable to NIM (China National Institute of Metrology), covering load cell, encoder, and speed verification at three points across the force range.
Can the system integrate with an existing LIMS or MES platform?
Via optional OPC UA or TCP/IP API module, the TFW-212 supports bidirectional data exchange with enterprise systems for automated result ingestion and equipment status monitoring.
What maintenance intervals are recommended?
Load cell verification every 12 months; optical encoder cleaning and mechanical inspection every 6 months; routine lubrication of lead screws per 2000 operational hours.
Is remote technical support available for international users?
Yes—Tuofeng offers web-based diagnostics, screen-sharing troubleshooting, and firmware updates via secure HTTPS portal, with English-speaking application engineers available during CET business hours.
