Tuofeng TFW-119 Microcomputer-Controlled Electromechanical Universal Tensile Testing Machine

Overview

The Tuofeng TFW-119 is a high-precision, microcomputer-controlled electromechanical universal tensile testing machine engineered for static mechanical property evaluation of metallic, polymeric, composite, and ceramic materials under uniaxial loading conditions. It operates on the principle of servo-controlled displacement actuation via a precision ball-screw transmission system, enabling accurate force application and real-time closed-loop feedback control. The system conforms to international metrological and performance standards including ISO 7500-1 (Class 0.5 accuracy), ASTM E4 (load verification), and ASTM E8/E8M (tensile testing of metallic materials), making it suitable for accredited laboratories operating under GLP, ISO/IEC 17025, or FDA 21 CFR Part 11-compliant environments where audit-trail functionality and data integrity are mandatory.

Key Features

• High-stiffness dual-column frame with reinforced base and crosshead assembly, designed to minimize deflection during high-load testing up to 200 kN.
• Imported AC servo motor coupled with worm-gear reduction gearbox ensures smooth, low-noise operation across the full speed range of 0.001–500 mm/min (infinitely variable, no gear shifting required).
• Precision-ground ball-screw drive system with preloaded nuts delivers consistent positioning repeatability and eliminates backlash-induced measurement artifacts.
• Integrated optical encoder-based displacement measurement system with 0.001 mm resolution and ±0.005% of reading accuracy, traceable to national metrology institutes.
• Dual-mode overload protection: hardware-level electronic limit switches + software-based emergency cutoff at 110% of rated load capacity.
• Quick/slow dual-speed crosshead movement with programmable return-to-start function, supporting both automated test sequences and manual setup operations.
• Modular fixture interface compatible with standardized wedge-action grips, compression platens, bend fixtures, peel jigs, and custom tooling per ASTM D638, ISO 527, ISO 604, and ISO 1133.

Sample Compatibility & Compliance

The TFW-119 accommodates specimens ranging from thin polymer films (≥0.05 mm thickness) to structural steel coupons (up to 50 mm wide × 25 mm thick), with adjustable test width (standard 400 mm, extendable to 600 mm) and extended travel (1000 mm). It supports standard and non-standard geometries per GB/T 228.1, ASTM E8, ISO 6892-1, and JIS Z2241. All force transducers are calibrated in accordance with ISO 376 and verified annually per JJG 475-2008. The system meets Class 0.5 accuracy requirements as defined in GB/T 16491-2008 and ISO 7500-1, ensuring traceability to SI units through documented calibration certificates.

Software & Data Management

The embedded Windows-based testing software provides multi-mode control (load-controlled, displacement-controlled, strain-controlled, and hold modes), real-time curve visualization (force–time, force–displacement, stress–strain, displacement–time), and automated parameter extraction—including ultimate tensile strength, yield strength (0.2% offset), Young’s modulus, elongation at break, reduction in area, compressive strength, flexural modulus, tear strength, and peel adhesion. Data export is supported in CSV, XLSX, and PDF formats; all test records include timestamped metadata, operator ID, environmental conditions (optional sensor integration), and digital signatures. Audit trail logs capture every user action, parameter change, and calibration event—fully compliant with FDA 21 CFR Part 11 requirements when configured with role-based access control and electronic signature modules.

Applications

This system serves as a primary mechanical characterization platform in R&D labs and QC departments across aerospace (e.g., titanium alloy fasteners per AMS 2300), automotive (composite leaf springs, brake hose reinforcement), medical device manufacturing (polymer sutures per ISO 10993-12), wire & cable (copper tensile strength per ASTM B3), rubber & elastomers (vulcanized compounds per ASTM D412), and construction materials (rebar, grout, fiber-reinforced cementitious composites per ASTM C1018). Its modular architecture allows seamless adaptation to specialized protocols such as creep rupture (ASTM E139), stress relaxation (ISO 899-1), and cyclic fatigue (ASTM D3479) with optional extensometer integration.

FAQ
