Tuofeng TFW-120 Microcomputer-Controlled Electromechanical Universal Tensile Testing Machine

Overview

The Tuofeng TFW-120 is a microcomputer-controlled electromechanical universal tensile testing machine engineered for high-precision mechanical property characterization of metallic, polymeric, composite, and ceramic materials. Based on the fundamental principles of quasi-static uniaxial force-displacement measurement, the system applies controlled load via a servo-driven crosshead actuated by a high-torque, low-backlash ball-screw transmission. Force is measured using a calibrated high-stability load cell with digital signal conditioning; displacement is tracked via an optical encoder coupled directly to the lead screw—ensuring traceable, repeatable metrology across the full operational range. Designed to meet Class 0.5 accuracy per ISO 7500-1 and GB/T 16491–2008, the TFW-120 delivers consistent performance under demanding R&D, QA/QC, and regulatory validation environments.

Key Features

• Full-scale force capacity of 200 kN with extended dynamic range (0.2–100% FS), enabling seamless evaluation from fine filaments to structural components.
• Constant-resolution force measurement at 1 part in 500,000 full-scale codes—no range switching required, eliminating step errors during multi-stage tests.
• Precision-ground preloaded ball screw with imported servo drive ensures smooth, backlash-free motion and long-term mechanical stability.
• Dual-speed automatic crosshead control (fast return + fine positioning) with programmable jog functionality for rapid specimen setup and post-test recovery.
• Integrated safety architecture: hardware-based electronic limit switches, redundant emergency stop circuitry, and automatic overload cutoff at 110% of rated capacity.
• Modular fixture interface compatible with standardized wedge-action grips, compression platens, bend fixtures, peel jigs, and custom tooling per ASTM D638, ISO 527, or user-defined geometries.

Sample Compatibility & Compliance

The TFW-120 accommodates specimens ranging from thin films (≥0.05 mm thickness) to heavy-section bars (up to Ø60 mm × 1000 mm length), with adjustable test width (400–600 mm) and vertical clearance (up to 1000 mm stroke). It supports standard test methods including tensile (ASTM E8/E21, ISO 6892-1), compression (ASTM E9, ISO 13314), flexure (ASTM D790, ISO 178), peel (ASTM D903, ISO 8510-2), and tear (ASTM D624, ISO 34-1). The system conforms to national and international metrological requirements: verified per JJG 475–2008 (China National Verification Regulation) and certified to ISO/IEC 17025 traceable calibration protocols. All mechanical and electrical subsystems comply with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards.

Software & Data Management

The Windows-based TensileMaster™ software provides full compliance with 21 CFR Part 11 requirements—including electronic signatures, audit trails, role-based access control, and immutable data archiving. It supports seven real-time control modes: constant rate of extension (CRE), constant rate of loading (CRL), load hold, displacement hold, strain control, closed-loop stress ramping, and multi-step cyclic protocols. Real-time plotting includes synchronized force–time, force–displacement, stress–strain, and displacement–time curves—with on-the-fly switching and overlay capability for comparative analysis. Calculated outputs include ultimate tensile strength (UTS), yield strength (Rp0.2), Young’s modulus, elongation at break, reduction in area, compressive yield stress, flexural modulus, peel adhesion energy, and tear propagation resistance. Data export is supported in CSV, XML, PDF, and proprietary .TMD formats; all reports include instrument ID, operator ID, environmental conditions, calibration certificate reference, and timestamped metadata.

Applications

The TFW-120 serves as a core mechanical testing platform across regulated and non-regulated sectors. In aerospace, it validates titanium alloy fasteners and carbon-fiber laminates per AMS and NADCAP requirements. In medical device manufacturing, it verifies tensile integrity of suture materials (USP ), balloon catheter burst pressure (ISO 10555-1), and orthopedic implant fatigue pre-screening. Automotive suppliers use it for rubber bushing hysteresis analysis, seatbelt webbing elongation, and battery pack structural bracket testing. Polymer labs apply it for melt-blown nonwoven tensile uniformity mapping and biodegradable film degradation profiling. Academic users leverage its open API for integration with digital twin models and machine learning–driven failure prediction workflows.

FAQ

What international standards does the TFW-120 support out-of-the-box?
The system includes preconfigured test templates for ASTM E8, ISO 6892-1, GB/T 228.1, DIN 50125, and JIS Z 2241—with customizable parameter sets for method-specific ramp rates, hold durations, and acceptance criteria.
Can the TFW-120 be integrated into a GLP/GMP laboratory information management system (LIMS)?
Yes—via OPC UA and HL7-compliant RESTful API interfaces; raw data streams and finalized reports can be pushed directly to validated LIMS platforms with full audit trail synchronization.
Is deformation measurement included as standard equipment?
The base configuration includes high-resolution crosshead displacement tracking; extensometer support (contact and non-contact) is available as an optional module compliant with ISO 9513 Class 1 accuracy.
How is calibration maintained over time?
The system features automated self-diagnostic routines and scheduled verification prompts; factory-certified recalibration services are available globally, with NIST-traceable certificates issued per ISO/IEC 17025.
Does the software support multi-language operation in production environments?
Yes—interface language (English, Simplified Chinese, Traditional Chinese, German, French, Japanese) and report output language are independently configurable per user profile without system restart.
