Overview
The Tuofeng TFW-115 Electronic Universal Tensile Testing Machine is a high-precision electromechanical system engineered for static mechanical property characterization of metallic, polymeric, composite, and ceramic materials under uniaxial loading conditions. Based on closed-loop servo-controlled force and displacement actuation, the machine implements standardized quasi-static testing protocols defined by ISO 6892-1 (tensile testing of metallic materials), ASTM E8/E221 (tensile testing of metals), ASTM D638/D790 (plastics), and GB/T 228.1 (Chinese national standard for metallic tensile testing). Its modular architecture supports interchangeable load cells, extensometers, and fixture sets to accommodate diverse specimen geometries—from miniature fasteners and wire specimens to structural coupons and molded polymer bars—within a rigid, thermally stable frame designed to minimize parasitic deflections and ensure traceable force transmission.
Key Features
- High-stiffness dual-column frame with preloaded ball-screw drive system ensuring minimal axial compliance and repeatable crosshead positioning.
- Imported high-torque servo motor coupled with precision worm-gear reduction for smooth, low-noise operation across the full speed range (0.001–500 mm/min).
- Integrated load cell with 500,000-count A/D resolution and verified linearity ≤±0.5% of full scale per ISO 7500-1 Class 0.5 certification.
- Optical encoder-based displacement measurement with 0.001 mm resolution and accuracy conforming to JJG 475-2008 metrological verification requirements.
- Dual-speed programmable crosshead movement: rapid positioning (up to 300 mm/min) and fine-adjustment mode (<1 mm/min) for precise specimen alignment and clamping.
- Multi-level safety architecture including hardware-based emergency stop, dual electronic end-limit switches, and software-enforced overload cutoff at 110% of rated capacity.
- Modular fixture interface supporting standardized wedge-action grips, pneumatic clamps, compression platens, bend fixtures, peel jigs, and custom-designed fastener-specific holders.
Sample Compatibility & Compliance
The TFW-115 accommodates specimens ranging from M2–M24 threaded fasteners (bolts, screws, studs) to flat sheet metal strips (up to 600 mm wide × 1000 mm gage length), extruded profiles, elastomeric O-rings, and fiber-reinforced laminates. It meets mechanical and metrological requirements of ISO 7500-1 (static calibration of testing machines), ISO 5893 (tensile/compression testing equipment), and GB/T 16491-2008 (electronic universal testing machine manufacturing standard). All force and displacement data paths are validated for traceability to national standards (e.g., CNAS-accredited calibration certificates available upon request). Optional configurations include ASTM E8-compliant extensometer mounts, environmental chamber integration ports, and GLP/GMP-ready audit trail modules compliant with FDA 21 CFR Part 11 when paired with validated software packages.
Software & Data Management
Tuofeng’s proprietary TensilePro v4.2 software operates natively on Windows 10/11 platforms and supports multilingual UI (English, Simplified Chinese, Traditional Chinese). The application enables real-time control of force, displacement, or strain rate modes—including hold, ramp-hold, cyclic, and step-load protocols—and displays synchronized force–displacement, stress–strain, and time-series curves with user-defined scaling and overlay capabilities. Raw data is stored in encrypted .tdb binary format with embedded metadata (operator ID, timestamp, calibration ID, environmental conditions). Export options include CSV, Excel, PDF reports (with customizable templates), and XML for LIMS integration. Version-controlled firmware updates, automated backup scheduling, and role-based user permissions (admin/operator/viewer) support regulated laboratory environments. Audit trail logging records all parameter changes, test executions, and data modifications with immutable timestamps.
Applications
The TFW-115 serves as a primary verification tool for mechanical integrity assessment across multiple industrial domains: bolt preload verification and proof load testing per ISO 898-1; shear strength evaluation of riveted or bonded joints; tensile yield and ultimate strength determination of aerospace aluminum alloys (e.g., 7075-T6); elongation-at-break and modulus measurement of thermoplastic injection-molded components; compressive yield behavior of powder metallurgy sintered parts; peel adhesion testing of pressure-sensitive tapes per ASTM D903; and flexural rigidity quantification of composite laminates per ASTM D7264. Its adaptability makes it suitable for R&D labs validating new alloy formulations, QC laboratories performing incoming material inspection, and third-party testing facilities executing accredited conformity assessments.
FAQ
What standards does the TFW-115 comply with for calibration and verification?
It conforms to ISO 7500-1 (Class 0.5), JJG 475-2008, GB/T 16491-2008, and supports traceable calibration using NIST-traceable reference load cells and displacement standards.
Can the system be configured for fastener-specific testing per ISO 898 or SAE J429?
Yes—dedicated fastener test fixtures, wedge grips, and nut-turning adapters are available; software includes preconfigured test methods for proof load, yield strength, and tensile strength per ISO 898-1 and ASTM F606.
Is 21 CFR Part 11 compliance supported out-of-the-box?
The base software provides audit trail functionality; full 21 CFR Part 11 compliance (electronic signatures, system validation documentation, access controls) requires optional GxP module activation and site-specific IQ/OQ/PQ validation support.
What is the maximum specimen width supported without modification?
Standard configuration supports 400 mm effective test width; extended columns and reinforced crossheads enable customization up to 600 mm upon request.
Does the machine support real-time strain measurement via extensometry?
Yes—both clip-on axial extensometers (for modulus and yield point detection) and non-contact video extensometers can be integrated via standardized mounting interfaces and calibrated within the software environment.
