Overview
The Tuofeng TFW-301 is a high-stiffness, microcomputer-controlled electromechanical universal testing machine engineered for precision mechanical property evaluation of metallic, polymeric, composite, and elastomeric materials. It operates on the principle of closed-loop servo-controlled axial loading, where force is applied via a high-rigidity load frame driven by an imported servo motor and transmitted through a preloaded recirculating ball screw. The system conforms to ISO 7500-1 (Class 0.5), ASTM E4, and GB/T 16491–2008 standards for static testing machines, ensuring traceable metrological performance across its full 300 kN capacity range. Designed for laboratory and industrial QA/QC environments, the TFW-301 delivers repeatable, temperature-stable force measurement with ±0.5% load accuracy and sub-micron displacement resolution — critical for evaluating tensile strength, yield behavior, modulus, fracture toughness, and creep response under standardized protocols.
Key Features
- Full-scale load capacity of 300 kN with dual-range high-precision load cell, calibrated to ISO 376 Class 0.5 specifications
- High-rigidity dual-column steel frame with optimized crosshead guidance for minimal deflection during compression and bending tests
- Imported servo drive system coupled with low-backlash worm-gear reduction ensures smooth, noise-free operation from 0.001 mm/min to 500 mm/min
- Optical encoder-based displacement feedback with ±0.005% reading accuracy and real-time synchronization to force acquisition at 1 kHz sampling rate
- Modular extensometry support: compatible with clip-on axial extensometers (0.2–100 mm gauge length) and non-contact video extensometers (optional)
- Dual safety architecture: hardware-level emergency stop circuitry integrated with software-enforced overload cutoff (>110% FS) and programmable soft limits
- Quick-return function with dual-speed actuation (fast positioning + fine approach) reduces cycle time between successive specimens
Sample Compatibility & Compliance
The TFW-301 accommodates standardized test specimens per ASTM D638 (plastics), ASTM E8/E21 (metals), ISO 527, ISO 6892-1, GB/T 228.1, and JIS Z2241. Its configurable test width (standard 400 mm, extendable to 1000 mm) and vertical stroke (800 mm base, expandable) enable testing of structural profiles, laminates, geotextiles, and packaging straps — including PP/PE/PET strapping used in logistics and palletizing applications. All mechanical and electrical components meet CE Machinery Directive 2006/42/EC requirements. Calibration certificates are provided with NIST-traceable reference standards. The system satisfies GLP documentation requirements and supports 21 CFR Part 11-compliant audit trails when configured with role-based user authentication and electronic signature modules.
Software & Data Management
Tuofeng TestSuite™ v5.2 is a Windows-based, multi-language (English, Simplified/Traditional Chinese) testing platform compliant with ISO 17025 data integrity principles. It supports ASTM-defined control modes: constant rate of extension (CRE), constant rate of loading (CRL), load hold, displacement hold, and cyclic ramp-hold sequences. Real-time plotting includes force–time, stress–strain, force–displacement, and strain–time overlays with automatic peak detection and tangent modulus calculation. Data export formats include CSV, XML, and PDF reports with embedded metadata (operator ID, timestamp, calibration ID, environmental conditions). Raw data files are stored in encrypted binary format with SHA-256 checksum verification. Software updates are delivered via secure HTTPS channel; lifetime maintenance includes version upgrades and regulatory compliance patches.
Applications
The TFW-301 serves as a primary mechanical characterization tool in R&D laboratories and production QA departments across multiple sectors. In packaging engineering, it validates tensile strength, elongation-at-break, and relaxation behavior of woven/non-woven strapping tapes and PET捆扎带 per ISO 10319 and GB/T 22344. In aerospace composites, it performs interlaminar shear (ASTM D2344) and compression-after-impact (CAI) per Boeing BSS 7260. In medical device manufacturing, it verifies tensile properties of suture materials (ISO 10555-1) and balloon catheter burst pressure (ASTM F1985). Additional use cases include rubber vulcanizate testing (ASTM D412), adhesive bond strength (ASTM D1002), and powder metallurgy green strength analysis (MPIF Standard 44).
FAQ
What standards does the TFW-301 comply with for force calibration?
