Tuofeng TFW-68 Advanced Microcomputer-Controlled Electromechanical Universal Testing Machine

Overview

The Tuofeng TFW-68 is a high-precision electromechanical universal testing machine engineered for static mechanical property characterization of metallic, polymeric, composite, and ceramic materials under tension, compression, bending, shear, peel, tear, and puncture loading conditions. Based on servo-controlled electromechanical actuation and high-resolution load cell transduction, the system implements closed-loop control of force, displacement, and strain via real-time feedback from integrated load cells, optical encoders, and optional extensometers. Its modular architecture supports seamless integration with standardized test fixtures and conforms to international metrological requirements for Class 0.5 accuracy per ISO 7500-1 and GB/T 16491-2008. Designed for laboratory and industrial QA/QC environments, the TFW-68 delivers repeatable, traceable, and audit-ready data essential for material certification, process validation, and R&D benchmarking across regulated sectors including aerospace, automotive, medical device manufacturing, and construction materials science.

Key Features

• Precision electromechanical drive system featuring imported servo motor coupled with high-rigidity planetary gear reducer and preloaded precision ball screw assembly for smooth, backlash-free motion control
• Full-scale force measurement range from 0.2% to 100% FS with ±0.5% accuracy (per ISO 7500-1) and internal resolution of 1 part in 500,000 codes—no range switching required
• Adjustable crosshead travel up to 1000 mm with dual-speed (fast/slow) automated positioning and programmable return-to-start functionality
• Optical encoder-based displacement measurement with 0.001 mm resolution and ±0.005% of reading accuracy
• Comprehensive safety architecture including electronic limit switches, emergency stop circuitry, overload protection (auto-shutdown at >110% FS), and mechanical overload buffer
• Modular fixture interface compatible with standardized wedge-action grips, compression platens, bend fixtures, peel jigs, and custom tooling per ASTM D638, D790, D1876, ISO 527, ISO 178, and GB/T 228.1

Sample Compatibility & Compliance

The TFW-68 accommodates specimens ranging from thin films (<0.1 mm) to structural steel sections (up to 200 mm width × 50 mm thickness), with effective test width configurable up to 600 mm. It supports standard and non-standard geometries—including dog-bone tensile bars, cylindrical compression samples, notched impact coupons (with optional accessories), and laminated composites—across ambient temperature conditions. The system meets calibration and verification requirements per JJG 475-2008 (China National Verification Regulation) and is validated against reference standards traceable to NIM (National Institute of Metrology, China). For global compliance, it supports test execution and reporting aligned with ASTM E4 (load verification), ISO 7500-1 (static calibration), ISO 527 (plastics tensile), ISO 178 (flexural properties), and EN 10002-1 (metallic materials). All hardware and firmware configurations are documented to support GLP/GMP audit readiness.

Software & Data Management

The Windows-based Tuofeng TestSuite software provides full IEC 62304-compliant control and analysis capabilities. It supports multiple test modes—including force-controlled ramp, displacement-controlled ramp, strain-controlled ramp, hold-at-load, hold-at-displacement, and cyclic loading—with user-definable ramp rates (0.001–500 mm/min, infinitely variable). Real-time visualization includes synchronized plots of load vs. time, load vs. displacement, stress vs. strain, and extension vs. time. Software features include automatic calculation of tensile strength, yield strength (0.2% offset), elongation at break, Young’s modulus, compressive strength, flexural modulus, peel strength, tear resistance, and adhesion energy. Data export is available in CSV, Excel, PDF, and XML formats; all raw acquisition timestamps, metadata, and operator inputs are embedded for full traceability. Audit trail functionality records all parameter changes, test executions, and report generations—supporting FDA 21 CFR Part 11 compliance when deployed with electronic signature modules.

Applications

The TFW-68 serves as a primary mechanical characterization platform in diverse application domains: qualification of aerospace-grade aluminum alloys and titanium sheets per AMS and MIL-STD specifications; validation of polymer melt strength and filler dispersion effects in thermoplastic composites; mechanical screening of battery electrode coatings and separator membranes; tensile evaluation of medical-grade silicone tubing and suture materials per ISO 10993-12; compressive testing of concrete cores and geopolymer mortars in civil engineering labs; and peel/adhesion assessment of pressure-sensitive adhesives used in electronics assembly. Its adaptability to multi-axis fixturing also enables research into anisotropic behavior of additively manufactured lattice structures and fiber-reinforced laminates.

FAQ
