Tuofeng TFW-104 Dual-Column Microcomputer-Controlled Electromechanical Universal Testing Machine

Overview

The Tuofeng TFW-104 is a dual-column, microcomputer-controlled electromechanical universal testing machine engineered for high-precision mechanical property evaluation of metallic, non-metallic, and composite materials. It operates on the principle of controlled axial force application via a servo-driven ball screw actuation system, enabling reproducible uniaxial loading under displacement- or load-controlled conditions. Designed in strict accordance with GB/T 16491–2008 and JJG 475–2008 metrological verification standards, the TFW-104 delivers class 0.5 accuracy per ISO 7500-1 and ASTM E4—ensuring traceability, linearity, and long-term stability across its full 10 kN capacity. Its rigid frame architecture, coupled with high-resolution optical displacement feedback and sub-micron load resolution (1 part in 500,000 full-scale), supports rigorous R&D validation, quality control, and regulatory compliance workflows in industrial and academic laboratories.

Key Features

• Dual-column steel frame with reinforced crosshead guidance ensures minimal deflection and high lateral stiffness during high-force tensile, compression, bending, shear, tear, peel, and puncture tests.
• Imported servo motor and precision worm-gear reducer provide smooth, low-noise motion control across the full speed range (0.001–500 mm/min), supporting both quasi-static and dynamic rate-dependent characterization.
• High-accuracy ball screw transmission eliminates backlash and maintains positional repeatability within ±0.005% of reading—critical for modulus determination and yield point detection.
• Integrated safety architecture includes electronic travel limits, hardware emergency stop circuitry, software-based overload cutoff (triggered at 110% of rated load), and automatic return-to-initial-position functionality post-test.
• Motorized crosshead with dual-speed jog control enables rapid setup and precise specimen alignment without manual intervention.
• Modular fixture interface accommodates standardized grips (e.g., wedge-action, pneumatic, hydraulic) and custom tooling for specialized geometries including fasteners, wires, films, and elastomeric components.

Sample Compatibility & Compliance

The TFW-104 supports mechanical testing of specimens ranging from miniature fasteners (M2–M12 bolts, screws, rivets) to structural plates and polymer sheets. With optional extensometers (contact or non-contact), it meets ASTM E8/E21 requirements for strain measurement in metallic tensile testing and ISO 527-2 for plastics. The system is fully compliant with international test standards including ASTM D638 (plastics), ASTM D3039 (composites), ISO 6892-1 (metal tensile), ISO 178 (flexural), ISO 148 (impact-ready configuration), and EN 10002-1. Calibration certificates are NIST-traceable and compatible with GLP/GMP audit documentation requirements, including full audit trail logging per FDA 21 CFR Part 11 when paired with validated software configurations.

Software & Data Management

The Windows-based TFW TestSuite software provides multi-language support (English, Simplified/Traditional Chinese), unit flexibility (N/kN/lbf, mm/in, MPa/psi), and real-time plotting of up to four synchronized curves: load–time, load–displacement, stress–strain, and displacement–time. It supports closed-loop control modes—including constant-rate loading, constant-strain-rate, load-hold, displacement-hold, and cyclic protocols—with programmable ramp/hold segments. All raw data are stored in encrypted binary format with timestamped metadata; results export natively to CSV, PDF, and XML for LIMS integration. Software features include curve overlay comparison, statistical reporting (min/max/mean/std dev), batch processing, automated report generation with company logo embedding, and user-level access controls. Firmware and software updates are delivered remotely, with lifetime technical support and version upgrades included.

Applications

The TFW-104 serves as a primary mechanical characterization platform across multiple sectors: fastener manufacturers use it for proof-load verification, tensile strength grading (per ISO 898-1), and thread stripping analysis; aerospace suppliers perform shear and bearing tests on rivets and bolted joints per NASM 1312; automotive Tier-1 suppliers validate plastic clips, gaskets, and composite brackets under ISO 179 and ASTM D790; rubber and elastomer labs conduct tear (ASTM D624) and peel (ASTM D903) assessments; and academic institutions employ it for fundamental material modeling, constitutive law validation, and fracture mechanics studies. Its adaptability to ISO-standardized fixtures and environmental chambers (optional) further extends utility into elevated-temperature or humidity-controlled testing regimes.

FAQ

What standards does the TFW-104 comply with for fastener testing?
It conforms to ISO 898-1, ISO 3506-1, ASTM F606, and DIN 267-4 for mechanical property assessment of bolts, screws, and studs—including proof load, tensile strength, yield strength, and elongation.
Can the system be integrated into an existing LIMS or MES environment?
Yes—the software supports ODBC-compliant database connectivity and structured XML data export, enabling seamless integration with laboratory information management systems and manufacturing execution systems.
Is third-party calibration certification available?
Tuofeng provides factory calibration with NIST-traceable documentation; accredited third-party calibration services (ISO/IEC 17025) can be arranged upon request.
What is the warranty coverage and service response time?
Standard warranty is 24 months parts-and-labor; extended service plans include remote diagnostics, on-site preventive maintenance, and priority spare parts logistics.
Does the machine support cyclic fatigue testing?
While the base configuration is optimized for static and quasi-static tests, fatigue-capable versions with enhanced controller firmware and high-cycle-duty load cells are available as configurable options.
