Overview
The Tuofeng TFW-82 is a high-precision electromechanical universal tensile testing machine engineered for static mechanical property characterization of metallic, polymeric, composite, and elastomeric materials. It operates on the principle of controlled displacement actuation via a servo-motor-driven precision ball screw system, enabling accurate application and measurement of uniaxial tensile, compressive, flexural, shear, tear, peel, and puncture loads. Designed to meet international metrological and regulatory requirements—including ISO/IEC 17025 traceability frameworks—the system delivers repeatable, auditable force-displacement data essential for R&D validation, quality control, and regulatory submissions. Its rigid C-frame architecture, coupled with dual-speed crosshead control and integrated overload protection, ensures operational stability across extended test cycles and high-load regimes up to 200 kN.
Key Features
- High-resolution force measurement with ±0.5% accuracy over 0.2–100% FS, compliant with ISO 7500-1 Class 0.5 calibration standards
- Precision ball screw drive system paired with imported servo motor and worm-gear reducer for smooth, low-noise motion control
- 1000 mm vertical travel range with 0.001 mm displacement resolution, supporting both standard and extended-height specimen configurations
- Dual-mode crosshead control: rapid positioning (up to 500 mm/min) and fine-adjustment mode (0.001 mm/min), fully programmable via software
- Integrated safety architecture including electronic limit switches, emergency stop circuitry, and automatic over-load cutoff at 110% of rated capacity
- Modular fixture interface compatible with standardized grips (e.g., wedge-action, pneumatic, hydraulic) and custom tooling per ASTM D638, ISO 527, or GB/T 1040 specifications
Sample Compatibility & Compliance
The TFW-82 accommodates specimens ranging from thin polymer films (≥0.1 mm thickness) to structural steel coupons (up to 60 mm width × 25 mm thickness), with optional test widths of 400 mm, 500 mm, or 600 mm. It supports standardized test methods across global regulatory frameworks: ASTM D638 (tensile), D790 (flexure), D1876 (peel), D624 (tear); ISO 527, 178, 1133; GB/T 1040, 9341, 1447; and JIS K7113. All hardware and firmware comply with GB/T 16491-2008 (Chinese national standard for electronic universal testers) and JJG 475-2008 (verification regulation). Calibration certificates are traceable to NIM (National Institute of Metrology, China) and support third-party audit readiness under GLP and GMP environments.
Software & Data Management
The Windows-based TensilePro™ software provides full test configuration, real-time data acquisition, and post-processing capabilities in English, Simplified Chinese, and Traditional Chinese. It supports multiple control modes—constant rate of extension (CRE), constant load, constant strain, and hold-to-target—enabling compliance with USP <1041>, ISO 6892-1, and ASTM E8/E21 protocols. Real-time plotting includes stress–strain, load–displacement, load–time, and strain–time curves, with automatic calculation of tensile strength, yield point (0.2% offset), elongation at break, Young’s modulus, compressive strength, tear resistance, and peel adhesion. Data export is available in CSV, XLSX, and PDF formats; all test records include embedded metadata (operator ID, timestamp, calibration ID, environmental conditions) for 21 CFR Part 11-compliant audit trails when configured with electronic signature modules.
Applications
The TFW-82 serves as a core instrumentation platform in material science laboratories, QC/QA departments, and certification bodies across aerospace (e.g., carbon-fiber laminate compression testing per ASTM D6641), automotive (rubber bushing compression, seat belt webbing tensile), medical device manufacturing (suture tensile strength per ISO 10993-12), packaging (film seal peel strength per ASTM F88), and construction (rebar tensile verification per ISO 6892-1). Its adaptability to multi-specimen batch testing, combined with automated report generation and database archiving, streamlines conformity assessment workflows for ISO 9001, IATF 16949, and AS9100-certified organizations.
FAQ
What standards does the TFW-82 support for calibration and verification?
It complies with GB/T 16491-2008, JJG 475-2008, ISO 7500-1 Class 0.5, and ASTM E4 for force calibration, with optional NIST-traceable certificate packages.
Can the system be integrated into an existing LIMS or MES environment?
Yes—via TCP/IP or RS232 communication protocols, with configurable data output fields and support for ASTM E1382-compliant data exchange schemas.
Is deformation measurement supported beyond crosshead displacement?
Yes—optional high-accuracy extensometers (contact or non-contact) can be added for strain measurement per ISO 9513, achieving ±0.5% strain accuracy down to 0.001% strain resolution.
What maintenance intervals are recommended for long-term accuracy?
Annual verification by accredited metrology lab is advised; routine user checks (pre-test zero drift, load cell linearity, encoder feedback) should be performed per SOP prior to each shift.
Does the software support multi-language reporting for multinational labs?
Yes—test reports auto-generate in the selected UI language, with customizable templates supporting bilingual (e.g., English–Chinese) header/footer fields and unit annotations.
