Tuofeng TFW-151 Intelligent Microcomputer-Controlled Servo Universal Testing Machine

Overview

The Tuofeng TFW-151 Intelligent Microcomputer-Controlled Servo Universal Testing Machine is a high-precision electromechanical testing system engineered for static mechanical property evaluation of metallic, polymeric, composite, ceramic, and elastomeric materials. Based on closed-loop servo-controlled displacement and load regulation, the system implements fundamental uniaxial testing principles per ISO 6892-1 (tensile), ISO 14577 (hardness-indentation correlation), ASTM D695 (compression), ASTM D790 (flexure), and ASTM D638 (plastic tensile). Its architecture integrates a rigid dual-column frame, high-stiffness preloaded ball screw transmission, and a calibrated load cell with 0.5-class metrological accuracy—ensuring traceable force measurement across 0.2–100% of its 150 kN full-scale capacity. Designed for laboratory and production QC environments, the TFW-151 meets structural integrity requirements for ISO/IEC 17025-accredited material testing laboratories and supports validation protocols aligned with GMP and GLP frameworks.

Key Features

• Rigid welded steel frame with reinforced crosshead guidance, minimizing lateral deflection during high-load compression tests up to 150 kN
• Imported industrial-grade servo motor coupled with a backlash-free worm-gear reducer, delivering smooth torque transmission and thermal stability over extended duty cycles
• Constant-resolution force sensing (1:500,000) without range switching—eliminating recalibration drift between low-force (e.g., thin film peel) and high-force (e.g., structural alloy tensile) regimes
• Dual-mode crosshead control: high-speed (up to 500 mm/min) for rapid positioning; fine-adjustment jog mode (0.001 mm increments) for precise specimen alignment
• Integrated safety architecture including hardware-based emergency stop, programmable electronic limits, and automatic overload shutdown at 110% of rated capacity
• Modular extensometry support: compatibility with clip-on axial extensometers (ASTM E83 Class B-1), non-contact video extensometers (for high-temperature or brittle fracture analysis), and large-strain transducers (for rubber/elastomer elongation >1000%)

Sample Compatibility & Compliance

The TFW-151 accommodates specimens ranging from miniature micro-tensile coupons (1 mm wide) to full-section structural components (up to 600 mm wide × 800 mm stroke). Standard fixtures include wedge-action tensile grips, compression platens (100 mm diameter), three-point bend fixtures (span adjustable 20–500 mm), and shear adapters per ASTM D5379. Custom tooling—such as peel test blocks (ASTM D903), tear resistance notched dies (ASTM D624), and burst strength clamps—is available upon specification. The system complies with national and international metrological standards: GB/T 16491–2008 (Chinese standard for electronic UTM design), JJG 475–2008 (verification regulation), ISO 7500-1:2018 (static calibration of force-proving instruments), and ASTM E4–2022 (load verification procedures). Optional 21 CFR Part 11-compliant software modules provide electronic signatures, audit trails, and role-based user permissions for regulated industries.

Software & Data Management

Tuofeng’s proprietary TESTMaster™ software (v5.3+) runs natively on Windows 10/11 and supports six real-time display modes: load–time, load–displacement, stress–strain, displacement–time, strain–time, and dual-curve overlay. All test parameters—including gauge length, cross-sectional area, and environmental conditions—are logged with timestamps and operator ID. Raw data exports to CSV, Excel, and XML formats; graphical reports comply with ISO 5893 annexes for curve annotation and metadata embedding. The software enables automated sequence testing (e.g., cyclic loading per ASTM D3479), hold-step control (constant load/strain dwell per ISO 6892-2), and modulus calculation via secant/tangent methods. Data integrity safeguards include encrypted local storage, automatic versioned backups, and optional networked database synchronization with LIMS integration (ODBC/API support).

Applications

The TFW-151 serves as a primary mechanical characterization platform across R&D and quality assurance workflows. In aerospace, it validates titanium alloy sheet formability (ASTM E2234) and carbon-fiber laminate interlaminar shear strength (ASTM D2344). In automotive, it certifies brake pad compressibility (SAE J661) and EV battery module housing impact resistance (UN 38.3 mechanical shock simulation). For medical device manufacturers, it verifies suture tensile strength (ISO 10555-1) and polymer stent radial force (ASTM F2082). In construction materials testing, it performs concrete cylinder compression (ASTM C39), rebar yield mapping (ASTM A615), and geotextile puncture resistance (ASTM D4833). Academic users leverage its open API for custom algorithm integration—e.g., digital image correlation (DIC) synchronization or machine learning–driven failure prediction models.

FAQ

What standards does the TFW-151 support out-of-the-box?
The base configuration conforms to GB/T 16491–2008, JJG 475–2008, ISO 7500-1, and ASTM E4. Pre-loaded test templates cover ASTM D638, D695, D790, ISO 6892-1, and EN 10002-1. Additional standards modules (e.g., ISO 527, ASTM D882) are licensable.
Can the system be validated for FDA-regulated environments?
Yes—when equipped with the 21 CFR Part 11 Option Pack, the TFW-151 provides electronic signature enforcement, immutable audit logs, and configurable user privilege tiers required for pharmaceutical packaging or implantable device mechanical testing.
Is remote diagnostics and firmware updates supported?
All units include embedded Ethernet and optional 4G LTE connectivity. Tuofeng’s SecureLink™ portal enables encrypted remote troubleshooting, calibration certificate retrieval, and over-the-air software updates—with change logs archived in the system audit trail.
What is the warranty and service coverage?
Standard coverage includes 24 months parts-and-labor warranty, lifetime software upgrades, and priority response SLA (4-hour remote, 72-hour on-site for Tier-1 regions). Extended service contracts include annual metrological recalibration and preventive maintenance.
How is traceability maintained for accredited labs?
Each unit ships with NIST-traceable calibration certificates for load, displacement, and strain channels. Certificate validity intervals align with ISO/IEC 17025 Clause 6.5; calibration artifacts are certified by CNAS-accredited providers per ISO/IEC 17025:2017 Annex A.3.
