Tuofeng TFW-105 Dual-Column Microcomputer-Controlled Electronic Universal Testing Machine

Overview

The Tuofeng TFW-105 is a dual-column, microcomputer-controlled electromechanical universal testing machine engineered for high-precision mechanical property evaluation of metallic, non-metallic, and composite materials. Based on the principle of controlled axial force application via servo-driven ball screw actuation, it delivers traceable, repeatable load-displacement data compliant with international static mechanical testing standards. Its modular architecture supports standardized tensile, compression, bending, shear, tear, peel, and puncture tests—enabling full characterization of yield strength, ultimate tensile strength, elongation at break, Young’s modulus, compressive strength, flexural modulus, and Poisson’s ratio. Designed for laboratory and quality control environments, the TFW-105 meets the structural and metrological requirements of GB/T 16491–2008 and JJG 475–2008, and is validated for use in accordance with ASTM E4, ASTM E8/E8M, ISO 6892-1, ISO 7500-1, DIN 51221, JIS Z2241, and BS EN ISO 6892.

Key Features

• 0.5-class accuracy certified force measurement system with ±0.005% reading uncertainty across the full 0.2–100% load range
• High-resolution load cell (1 part in ±500,000) ensuring consistent resolution without manual range switching
• Precision-ground ball screw transmission paired with an imported servo motor and worm gear reducer for smooth, low-noise, backlash-free motion control
• Dual-speed automatic crosshead adjustment (fast/slow modes) with jog functionality and programmable return-to-start positioning
• Integrated safety suite: electronic end-limit switches, hardware emergency stop circuit, and automatic overload cutoff at 110% of rated capacity
• Modular fixture interface supporting ASTM/ISO-compliant grips, compression platens, bend fixtures, peel jigs, and custom tooling per material geometry and standard requirements
• Robust dual-column steel frame with vibration-damped base and rigid load train alignment to minimize parasitic bending moments

Sample Compatibility & Compliance

The TFW-105 accommodates specimens ranging from thin polymer films (≥0.1 mm thickness) to structural metal coupons (up to 25 mm thick), including rods, sheets, wires, composites, elastomers, and adhesively bonded joints. Standard test configurations align with specimen geometries defined in ASTM E8/E8M (tensile bars), ASTM D638 (plastics), ASTM D3039 (composites), ISO 527-2, ISO 178 (flexure), ISO 14130 (peel), and ISO 11339 (tear). All hardware and software functions are designed to support GLP/GMP-aligned workflows, including audit-trail-enabled user authentication, electronic signature capability, and test method version control—facilitating compliance with FDA 21 CFR Part 11 where required.

Software & Data Management

The Windows-based control and analysis software provides ISO/IEC 17025-compatible test execution and reporting. It supports multiple control modes—including constant rate of extension (CRE), constant load ramping, hold-at-load, hold-at-strain, and cyclic loading—and enables real-time display of up to four synchronized plots: load vs. time, load vs. displacement, stress vs. strain, and displacement vs. time. The software automatically calculates and exports standardized metrics (e.g., R_m, R_eH, A₅₀, E, σ_b) upon test completion using user-input cross-sectional area and gauge length. Data export options include CSV, XML, and PDF; batch reporting supports statistical summaries (mean, min, max, CV%) across replicate tests. Firmware and software updates are delivered remotely with version-locked calibration certificates and change logs for regulatory traceability.

Applications

This system serves as a core mechanical characterization platform across R&D, QC, and certification labs. In aerospace, it validates fastener integrity (e.g., bolt tensile strength per ASTM F606), composite layup performance, and thermal barrier coating adhesion. In automotive manufacturing, it verifies weld joint strength, elastomeric bushing stiffness, and battery pack structural component durability. Construction materials labs use it for rebar tensile grading (GB/T 1499.2), concrete reinforcement bond testing, and geosynthetic tensile verification. Within medical device development, it supports ISO 5832-compliant metallic implant testing and ISO 10993-12 extractable leachables substrate validation. Universities leverage its open API and scripting interface for advanced constitutive modeling and digital twin calibration.

FAQ

Does the TFW-105 comply with ISO/IEC 17025 calibration requirements?
Yes—the system is supplied with a factory calibration certificate traceable to NIM (China National Institute of Metrology), and all load cells and encoders are calibrated per ISO 376 and ISO 7500-1 protocols.

Can the software generate reports compliant with FDA 21 CFR Part 11?
Yes—audit trail logging, electronic signatures, and role-based access control are enabled by default and configurable per organizational SOPs.

Is third-party verification available for ASTM or ISO standard compliance?
Yes—Tuofeng partners with CNAS-accredited laboratories to provide independent verification reports against selected standards (e.g., ASTM E4, ISO 7500-1) upon request.

What is the warranty coverage and service response time?
Tuofeng provides a 24-month comprehensive warranty covering parts and labor, with remote diagnostics support and on-site service within 5 business days in Tier-1 Chinese cities.

Are custom test fixtures available for non-standard specimens?
Yes—engineering drawings and material specifications can be submitted for bespoke fixture design, including hydraulic wedge grips, pneumatic clamps, and high-temperature environmental chambers (–70°C to +300°C).
