Overview
The Tuofeng TFW-101 Microcomputer-Controlled Electronic Universal Testing Machine is a precision-engineered electromechanical system designed for static mechanical property evaluation of metallic, polymeric, ceramic, composite, and elastomeric materials. Based on the fundamental principles of uniaxial force application and controlled displacement, the machine employs a high-rigidity dual-column frame, preloaded ball screws, and a closed-loop servo-controlled actuation system to deliver stable load application and repeatable motion profiles. Its architecture complies with ISO 7500-1:2018 (static calibration of force-proving instruments), ASTM E4 (standard practices for force verification of testing machines), and GB/T 16491–2008 (Chinese national standard for electronic universal testing machines). The system supports both open-loop and closed-loop control modes—including load, displacement, strain, and time-based ramping—and is certified per JJG 475–2008 for metrological verification in China.
Key Features
- 0.5-class accuracy per ISO 7500-1 and GB/T 16491–2008, validated across the full dynamic range (0.2–100% FS)
- High-resolution force transduction with 1/±500,000 internal A/D resolution—no manual range switching required
- Imported servo motor coupled to a self-locking worm gear reducer ensures smooth, backlash-free motion and zero creep under sustained load
- Preloaded ground ball screw assembly with integrated anti-rotation guide delivers axial positioning repeatability better than ±0.005 mm
- Dual-speed crosshead control (fast jog + fine positioning) enables rapid setup and precise alignment prior to test initiation
- Multi-level safety architecture: hardware-based emergency stop, programmable electronic limits, overload cut-off at 110% FS, and mechanical end-stop redundancy
- Modular fixture interface compatible with standardized wedge-action, pneumatic, hydraulic, and custom-designed grips per ASTM E8, ISO 6892-1, and GB/T 228.1
Sample Compatibility & Compliance
The TFW-101 accommodates specimens ranging from thin films (≥0.1 mm thickness) to structural metal coupons (up to 30 mm thick, 40 mm wide), including ASTM-standard tensile bars (Type I–V), compression cylinders (Φ25–100 mm), three- and four-point bending beams (up to 200 mm span), peel strips, tear specimens (Trouser, Graves), and puncture discs. It supports full compliance testing per ISO 6892-1 (tensile), ISO 148-1 (Charpy impact prep), ASTM D638 (plastics tensile), ASTM D790 (flexural), ASTM D1876 (peel), ASTM D624 (tear), and GB/T 7314 (metal compression). All test protocols are traceable to NIST-traceable force calibration standards and documented in accordance with GLP and ISO/IEC 17025 requirements. The system meets electromagnetic compatibility (EMC) requirements per EN 61326-1 and electrical safety per EN 61010-1.
Software & Data Management
The embedded Windows-based testing software provides ISO/IEC 17025-compliant data acquisition and reporting functionality. It supports multi-mode control (load, displacement, strain, or time rate), real-time curve overlay (force–time, stress–strain, displacement–time), and automated parameter extraction—including ultimate tensile strength (UTS), yield strength (Rp0.2), Young’s modulus, elongation at break, compressive yield, flexural modulus, peel adhesion energy, and tear resistance. Units are fully configurable (N/kN/lbf, MPa/psi, mm/in, %), with language support for English, Simplified Chinese, and Traditional Chinese. All test data are stored with embedded metadata (operator ID, timestamp, environmental conditions, calibration certificate ID), audit trail logging (per FDA 21 CFR Part 11 requirements), and export capability to CSV, PDF, and XML formats. Software updates are provided free of charge for the lifetime of the instrument.
Applications
The TFW-101 serves as a primary mechanical characterization platform in quality control laboratories, R&D centers, and third-party certification bodies. Typical use cases include: validation of incoming raw material mechanical properties in automotive Tier-1 suppliers; tensile and fatigue pre-screening of aerospace aluminum alloys (e.g., 7075-T6, Ti-6Al-4V); compression testing of sintered powder metallurgy components; flexural analysis of fiber-reinforced polymer composites; peel strength assessment of medical device adhesive laminates; and tensile property mapping of thermoplastic elastomers used in wire insulation. It is routinely deployed in accredited labs performing testing for ASME BPVC Section II, MIL-STD-810, and IEC 60601-1 compliance documentation.
FAQ
What international standards does the TFW-101 support out-of-the-box?
The system includes preconfigured test methods for ASTM E8/E9/E21, ISO 6892-1/148-1/15630, GB/T 228.1/7314/1447, and JIS Z2241—fully editable to accommodate proprietary or emerging standards.
Can the machine be integrated into an existing LIMS or MES environment?
Yes—the software provides OPC UA and TCP/IP interfaces for bidirectional communication with laboratory information management systems and manufacturing execution systems, supporting structured data exchange via JSON or XML payloads.
Is third-party calibration and ISO/IEC 17025 accreditation support available?
Tuofeng partners with CNAS-accredited calibration laboratories in Shanghai, Suzhou, and Shenzhen to provide on-site force and displacement verification with full traceability to NIM (National Institute of Metrology, China) standards.
What is the warranty coverage and service response time?
Standard warranty is 24 months parts-and-labor, extendable to 36 months. Priority technical support is available via remote diagnostics during business hours (GMT+8), with on-site engineer dispatch within 72 hours for critical failures in Tier-1 Chinese cities.
Are high-temperature or environmental chamber options available?
Yes—optional furnace modules (–70°C to +1200°C), humidity chambers (10–95% RH), and vacuum enclosures (10⁻³ mbar) can be mechanically and software-integrated without compromising frame stiffness or measurement fidelity.
