Tuofeng TFW-67 Advanced Electromechanical Universal Testing Machine

Overview

The Tuofeng TFW-67 Advanced Electromechanical Universal Testing Machine is a high-stiffness, microprocessor-controlled static mechanical testing system engineered for precision force and displacement measurement across tensile, compression, bending, shear, peel, tear, and puncture modes. It operates on the fundamental principle of controlled axial loading via a servo-driven crosshead, coupled with real-time acquisition of load, displacement, and optional strain data through calibrated transducers and high-resolution feedback systems. Designed to meet international metrological standards—including ISO 7500-1 Class 0.5, ASTM E4, and GB/T 16491—the TFW-67 delivers traceable, repeatable mechanical property quantification essential for R&D validation, quality control, and regulatory compliance in regulated industries.

Key Features

• High-capacity load frame rated for 200 kN maximum static load, constructed from rigid dual-column structural steel with optimized moment resistance and minimal deflection under load.
• Precision ball-screw transmission system paired with an imported industrial servo motor and worm-gear reduction unit ensures smooth, low-noise, backlash-free motion across the full speed range (0.001–500 mm/min).
• True single-range force measurement architecture: 1:500,000 internal resolution over the entire 0.2–100% FS operating span—no range switching, no accuracy discontinuity.
• Displacement detection via quadrature optical encoder with 0.001 mm resolution and ±0.005% accuracy relative to full-scale travel (1000 mm).
• Integrated safety subsystem including programmable electronic end limits, hardware-based emergency stop circuitry, mechanical overload cutoff (>110% FS), and fail-safe crosshead return logic.
• Modular test space design: standard 600 mm effective width and 1000 mm vertical stroke—both dimensions configurable per application requirements (e.g., reinforced concrete beams or aerospace composites).

Sample Compatibility & Compliance

The TFW-67 accommodates specimens ranging from thin polymer films (<0.1 mm thickness) to structural steel coupons (up to 80 mm diameter), enabled by customizable grip systems—including wedge-action, pneumatic, hydraulic, and specialized fixtures for ISO 527, ASTM D638, ASTM D3039, ISO 178, and EN 1311-1 geometries. All mechanical and software functions comply with ISO/IEC 17025 technical requirements for testing laboratories. The system supports full traceability per GLP/GMP environments when configured with 21 CFR Part 11-compliant software modules—including electronic signatures, audit trails, and role-based access control. Calibration certificates are issued against NIST-traceable reference standards, and routine verification follows JJG 475-2008 and ISO 7500-1 procedures.

Software & Data Management

Tuofeng’s proprietary UniTest Pro v5.2 software operates natively on Windows 10/11 and provides six primary control modes: constant rate of extension (CRE), constant rate of loading (CRL), constant stress, constant strain, hold-to-load, and hold-to-displacement. Real-time plotting includes synchronized force–time, force–displacement, stress–strain, and displacement–time curves—with up to eight user-definable channels. Data export conforms to ASTM E1228 and ISO 10360-5 formats (CSV, XML, PDF, XLSX). Automated calculations include tensile strength, yield point (0.2% offset method), Young’s modulus, elongation at break, compressive yield strength, flexural modulus, peel adhesion energy, and tear propagation resistance. All test files retain metadata (operator ID, calibration date, environmental conditions) and support digital signature workflows aligned with FDA 21 CFR Part 11 Annex 11 requirements.

Applications

The TFW-67 serves as a core materials characterization platform across multiple sectors. In aerospace, it validates carbon-fiber-reinforced polymer (CFRP) laminates per ASTM D3410 and metallic fasteners per NASM 1312. In automotive, it performs tensile testing of high-strength steels (e.g., DP980, TRIP1000) per ISO 6892-1 and rubber bushings per ISO 37. For medical device manufacturers, it verifies suture tensile strength (ISO 10555-1), balloon burst pressure (ISO 10555-4), and polymer film seal integrity (ASTM F88). In construction, it assesses reinforcing bar ductility (GB/T 1499.2), mortar compressive strength (ISO 679), and geotextile tensile performance (ISO 10319). Academic users leverage its open API for custom algorithm integration in constitutive modeling and fracture mechanics research.

FAQ

What international standards does the TFW-67 support out-of-the-box?

The system includes preconfigured test methods for ASTM E8/E21, ISO 6892-1, GB/T 228.1, ISO 178, ASTM D790, and EN ISO 1133, with automated parameter derivation and report generation.
Can the TFW-67 be integrated into an existing LIMS or MES environment?

Yes—UniTest Pro supports OPC UA and RESTful API interfaces for bidirectional data exchange with laboratory information management systems (LIMS) and manufacturing execution systems (MES), including sample ID synchronization and result auto-posting.
Is third-party calibration certification available?

Tuofeng provides factory calibration with NIST-traceable documentation; additionally, accredited third-party calibration services (ISO/IEC 17025 certified labs) can be arranged upon request.
What is the warranty coverage and service response time?

Standard warranty is 24 months parts-and-labor; extended service contracts include remote diagnostics, on-site preventive maintenance, and priority 48-hour response for critical failures.
Does the system support multi-specimen sequential testing without operator intervention?

Yes—batch mode allows unattended execution of up to 999 test sequences with automatic grip repositioning, specimen ejection logic, and pass/fail decision rules based on user-defined thresholds.
