Tuofeng TFW-292 Electronic Universal Testing Machine

Overview

The Tuofeng TFW-292 Electronic Universal Testing Machine is a high-precision, servo-controlled electromechanical system engineered for static mechanical property characterization of metallic, non-metallic, and composite materials. Based on the fundamental principles of axial force application and displacement-controlled loading, it implements closed-loop feedback control via high-resolution load cells, optical encoders, and strain-sensing modules to deliver repeatable, traceable, and standards-compliant mechanical test data. Designed for laboratory and industrial quality control environments, the TFW-292 supports full-cycle tensile, compression, bending, shear, tear, peel, and puncture testing—enabling quantification of critical material parameters including ultimate tensile strength (UTS), yield strength (0.2% offset), Young’s modulus, fracture elongation, compressive strength, flexural modulus, and adhesion/shear strength. Its architecture adheres to metrological requirements defined in ISO 7500-1 (Class 0.5 accuracy), ensuring measurement integrity across the full 0.2%–100% of rated capacity (300 kN).

Key Features

• High-stiffness dual-column frame with precision-ground ball-screw drive system and imported servo motor coupled to planetary gear reducer for smooth, low-noise, and backlash-free motion control
• Load measurement via temperature-compensated, hermetically sealed 300 kN load cell with ±0.5% full-scale accuracy and resolution of 1/500,000 FS (no range switching required)
• Displacement measurement using quadrature optical encoder with ±0.005% reading accuracy; optional extensometer or large-deformation transducer for strain-critical applications (e.g., ISO 527, ASTM D638)
• Adjustable crosshead travel (standard 800 mm, extendable upon request) and wide test width (400–600 mm configurable) accommodate diverse specimen geometries and fixture assemblies
• Dual-speed automatic crosshead positioning (fast jog + fine approach) with programmable return-to-start function and emergency stop, overload cutoff (>110% FS), and electronic limit switches
• Modular grip system supporting wedge-action, pneumatic, hydraulic, and custom-designed fixtures for metals, plastics, textiles, composites, and thin films

Sample Compatibility & Compliance

The TFW-292 accommodates specimens ranging from miniature coupons (e.g., ASTM E8 sub-size bars) to structural profiles (up to 300 mm width × 50 mm thickness). It fully supports standardized test configurations per GB/T 228.1, ASTM E8/E9/E21, ISO 6892-1, ISO 37, ISO 178, DIN 53455, JIS Z 2241, and BS EN 10002-1. Calibration and verification procedures comply with JJG 475–2008 (China National Verification Regulation) and GB/T 16491–2008 (Electronic UTM Manufacturing Standard). System-level conformity includes traceability to national metrology institutes (NIM-certified load cells), documented uncertainty budgets, and audit-ready calibration records—supporting GLP, GMP, and ISO/IEC 17025 laboratory accreditation.

Software & Data Management

The Windows-based Tuofeng TestSuite v4.2 software provides ISO/IEC 17025-aligned data acquisition and reporting functionality. It supports multi-mode control—including constant-rate loading (mm/min or N/s), hold-at-load, hold-at-displacement, and cyclic protocols—with real-time display of force–time, stress–strain, force–displacement, and displacement–time curves. All units (N/kN/MPa, mm/inch, %) are user-selectable; language options include English, Simplified Chinese, and Traditional Chinese. The software enables automated parameter extraction (e.g., Rp0.2, Rm, A50mm, Eb), statistical analysis (max/min/mean across batches), curve overlay comparison, and export to CSV, PDF, or XML formats. Audit trails, electronic signatures, and 21 CFR Part 11–compliant user access controls (role-based permissions, password protection, session logging) are available as optional modules for regulated environments.

Applications

This system serves as a primary mechanical characterization platform in R&D labs and QC departments across aerospace (aluminum alloy sheet tensile testing per AMS 4027), automotive (sheet metal formability, weld joint strength), construction (rebar, structural steel, concrete reinforcement), wire & cable (tensile break load, elongation at break), rubber & plastics (tensile set, tear resistance per ASTM D624), and powder metallurgy (green strength, sintered density correlation). It is routinely deployed for supplier qualification, incoming material inspection, process validation, failure analysis, and standards compliance verification in third-party testing laboratories accredited to CNAS, UKAS, or A2LA.

FAQ

What standards does the TFW-292 support out-of-the-box?

It natively supports GB/T, ASTM, ISO, DIN, JIS, and BS test methods via preloaded test templates and calculation routines—requiring no manual formula entry.
Can the system be integrated into a factory MES or LIMS?

Yes—via TCP/IP or RS232 interface with configurable ASCII or Modbus RTU protocol; API documentation and OPC UA support are available under enterprise licensing.
Is third-party calibration certification included?

A NIM-traceable factory calibration certificate (including load, displacement, and strain channel verification) is supplied with each unit; annual recalibration services are offered globally.
What is the warranty and service coverage?

Standard 24-month parts-and-labor warranty; lifetime software updates and remote technical support included; on-site service contracts available in APAC, EMEA, and North America.
Are custom fixtures or environmental chambers supported?

Yes—Tuofeng provides engineering consultation for bespoke gripping solutions and integrates seamlessly with temperature chambers (–70°C to +300°C), humidity controllers, and vacuum enclosures.
