Tuofeng TFW-112 Electronic Universal Tensile Testing Machine

Overview

The Tuofeng TFW-112 Electronic Universal Tensile Testing Machine is a high-precision, microprocessor-controlled mechanical testing system engineered for static mechanical characterization of metallic, polymeric, elastomeric, composite, and ceramic materials. It operates on the principle of controlled displacement or load application via a servo-driven electromechanical actuation system, enabling accurate measurement of force, displacement, and strain under standardized uniaxial loading conditions. Designed in strict accordance with GB/T 16491–2008 (equivalent to ISO 7500-1:2018 Class 0.5), the system delivers traceable, reproducible results required for quality assurance, R&D validation, and regulatory submissions across global industrial and academic laboratories.

Key Features

• Robust structural architecture with reinforced steel frame and high-rigidity crosshead assembly, minimizing deflection during high-load testing (up to 200 kN).
• Precision preloaded ball screw transmission system coupled with an imported servo motor and worm gear reducer, ensuring smooth motion control, minimal backlash, and long-term dimensional stability.
• Full-scale force resolution of 1 part in 500,000 without range switching—maintaining consistent resolution across the entire 1 kg–200 kN measurement span.
• Dual-mode control capability: closed-loop load control (for creep, stress relaxation, or load-hold tests) and closed-loop displacement control (for tensile, compression, or flexural protocols).
• Integrated safety subsystem including programmable electronic limit switches, hardware-based emergency stop circuitry, and automatic overload cutoff at 110% of rated capacity.
• Quick/slow dual-speed crosshead adjustment with manual jog functionality and auto-return-to-initial-position post-test.
• Modular fixture interface supporting standardized grips (e.g., wedge-action, pneumatic, hydraulic) as well as custom-designed tooling for rubber dumbbells, O-rings, tire treads, and vulcanized sheet specimens.

Sample Compatibility & Compliance

The TFW-112 accommodates a broad spectrum of specimen geometries—from thin polymer films and elastomer strips to thick-section metal coupons and reinforced composites. Its configurable test width (standard 400 mm, extendable to 600 mm) and vertical clearance (1000 mm travel) allow evaluation of extruded profiles, molded parts, and layered assemblies. The system is fully compliant with international material testing standards including ASTM E8/E8M (tension), ASTM D412/D638 (rubber/plastic), ISO 6892-1 (metallic materials), ISO 37 (vulcanized rubber), GB/T 528 (Chinese rubber standard), and DIN 53504. All calibration procedures adhere to JJG 475–2008 and support GLP/GMP audit readiness through documented traceability to national metrology institutes.

Software & Data Management

The Windows-based testing software provides multi-language UI (English, Simplified/Traditional Chinese), customizable unit systems (N/kN/lbf, mm/inch, MPa/psi), and real-time display of up to four synchronized curves—including load vs. time, stress vs. strain, displacement vs. time, and extension vs. load. It supports automated parameter derivation per ISO 527 and ASTM D638: tensile strength, yield point (0.2% offset), elongation at break, modulus (secant/tangent), tear strength (ISO 34-1), peel adhesion (ASTM D903), and compression set (ISO 815). Raw data export is available in CSV, Excel, and XML formats; all test sessions include timestamped audit trails, user authentication logs, and digital signatures compatible with FDA 21 CFR Part 11 requirements when configured with optional electronic signature modules.

Applications

• Rubber & Elastomer Characterization: Curing state analysis, tensile set evaluation, hysteresis loop quantification, and fatigue precursor assessment under cyclic loading.
• Automotive Component Validation: Belt tensile integrity, hose burst resistance, bushing shear stiffness, and dynamic seal compression-recovery behavior.
• Wire & Cable Quality Control: Conductor pull-out force, insulation jacket adhesion, and jacket elongation compliance per UL 1581 or IEC 60227.
• Medical Device Materials: Biocompatible polymer tensile performance (e.g., silicone tubing, thermoplastic elastomers), suture breaking strength, and balloon burst pressure correlation.
• Construction Material Certification: Reinforcing bar yield plateau detection, geotextile grab strength, and asphalt binder tensile stiffness modulus (per EN 13587).
• Academic Research: Constitutive modeling input generation, fracture toughness estimation via J-integral methods, and viscoelastic parameter identification using ramp-hold-relax protocols.

FAQ

What standards does the TFW-112 support for rubber testing?
The system natively implements ISO 37, ASTM D412, GB/T 528, and DIN 53504 test methods, with pre-configured templates for dumbbell-type specimens, ring tensile configurations, and tear propagation protocols.
Can the machine perform compression and flexural tests in addition to tension?
Yes—equipped with appropriate platens, three-point bend fixtures, or compression dies, the TFW-112 executes ASTM E9 (compression), ASTM D790 (flexure), and ISO 604 without hardware modification.
Is third-party calibration certification included with delivery?
Each unit ships with a factory calibration certificate traceable to CNAS-accredited reference standards; optional UKAS or A2LA-certified field calibration services are available upon request.
How is data integrity ensured during long-duration tests?
The embedded controller maintains independent sampling at 1 kHz regardless of PC communication status; all raw acquisition data is buffered onboard and synchronized post-test to prevent loss during power interruption or software latency.
Does the software support automated report generation for ISO/IEC 17025 accredited labs?
Yes—the reporting engine generates PDF/Excel outputs containing instrument ID, operator ID, environmental conditions (if connected to optional temp/humidity sensors), uncertainty budgets per GUM methodology, and digital signatures meeting ILAC P14 requirements.
