TopFeng TFW-199 High-Temperature Tensile Testing Machine (Customizable)

Overview

The TopFeng TFW-199 High-Temperature Tensile Testing Machine is an electromechanical universal testing system engineered for precise mechanical property evaluation of metallic, polymeric, ceramic, and composite materials under elevated thermal conditions. It integrates a high-stability servo-driven loading frame with a thermally isolated, independently controlled high-temperature chamber—enabling true in-situ tensile testing from ambient up to 300 °C (customizable beyond). The system operates on the principle of controlled uniaxial force application while maintaining real-time thermal equilibrium across the gauge section; load is applied via a precision preloaded ball screw actuated by a brushless AC servo motor, with closed-loop displacement and load regulation conforming to ISO 7500-1 Class 0.5 and ASTM E4 calibration requirements. Designed for laboratory-based R&D, quality control, and materials certification workflows, the TFW-199 supports standardized test protocols including ASTM E21, ISO 6892-2, GB/T 228.2, and ASTM D638 (with appropriate fixtures), ensuring traceable, repeatable, and auditable mechanical data acquisition.

Key Features

• Robust dual-structure architecture: Separately mounted high-temperature chamber (304 stainless steel inner chamber, forced-air convection, ±1 °C temperature uniformity) and rigid C-frame electromechanical tester (200 kN capacity, 1000 mm stroke)
• High-resolution motion control: Servo motor + timing belt + preloaded ball screw transmission delivering 0.01–500 mm/min crosshead speed with <0.1% speed stability over full range
• Sub-micron displacement resolution: 0.0001 mm encoder-based position feedback synchronized with load cell output for accurate strain derivation
• Full-scale force measurement: Dual-range or single-range load cells calibrated to ISO 376, with ±0.5% accuracy across 0.4–100% FS
• Integrated safety interlocks: Automatic emergency stop triggered by overload, specimen rupture, thermal excursion, or power anomaly
• Modular fixture interface: Standard M12 threaded base compatible with ASTM-compliant grips (flat, round, wedge, pneumatic), extensometers (contact/non-contact), and environmental adapters

Sample Compatibility & Compliance

The TFW-199 accommodates specimens per ASTM E8/E21 (metals), ISO 6892-2 (high-temperature metals), ASTM D638/D3039 (polymers/composites), and GB/T 228.2 (Chinese national standard for high-temp tensile testing). Specimen geometries include flat strips (up to 40 mm width), rods (Ø3–25 mm), and custom-profiled components. The high-temperature chamber features a 300 × 250 × 600 mm internal workspace (customizable), enabling testing of assembled subcomponents or multi-point sensor-integrated coupons. All hardware and firmware comply with CE Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, and RoHS 2011/65/EU. Software meets FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with audit trail, user role management, and digital signature modules.

Software & Data Management

Control and analysis are performed using TopFeng TestMaster v4.x—a Windows-based, bilingual (English/Chinese) platform compliant with GLP/GMP documentation standards. The software provides real-time visualization of load–displacement, stress–strain, and time–temperature–load triaxial plots. Raw data are stored in .tdm (Test Data Matrix) format—an open binary structure supporting post-hoc reprocessing, batch statistical comparison (mean, SD, CV%), and export to CSV, Excel, MATLAB, or SPC-compatible formats. Calibration certificates (force, displacement, temperature) are digitally embedded and version-tracked. Optional modules include automated report generation (user-defined templates), ISO 17025-compliant uncertainty calculation per GUM, and networked data synchronization with LIMS via OPC UA or REST API.

Applications

• High-temperature creep and stress-rupture characterization of turbine alloys (Inconel, Hastelloy) and refractory metals
• Thermo-mechanical fatigue (TMF) pre-screening of aerospace composites and ceramic matrix composites (CMCs)
• Validation of weld integrity and heat-affected zone (HAZ) strength degradation at service temperatures
• Quality assurance of high-performance elastomers, thermoplastics, and fiber-reinforced polymers used in automotive under-hood applications
• Development and qualification of additive-manufactured (AM) metal parts subjected to thermal cycling
• Research into phase-transition-induced embrittlement in shape-memory alloys and high-entropy alloys

FAQ

What is the maximum operating temperature of the integrated furnace chamber?
Standard configuration supports up to 300 °C; optional upgrades extend to 600 °C (requiring molybdenum heating elements and quartz viewing window).
Can the system perform compression or flexural tests at elevated temperatures?
Yes—by installing compression platens or three/four-point bending fixtures compatible with the chamber’s internal geometry and thermal shielding.
Is third-party calibration and ISO/IEC 17025 certification available?
TopFeng provides factory calibration with NIST-traceable load cells and PT100 sensors; accredited third-party calibration services (e.g., SGS, TÜV, CNAS labs) can be arranged upon request.
Does the software support automated test sequencing for multiple specimens?
Yes—TestMaster supports programmable multi-step tests, including hold-at-load, ramp-to-temperature, dwell cycles, and conditional branching based on real-time parameter thresholds.
What environmental conditions are required for installation?
Ambient temperature: 5–40 °C; relative humidity: ≤80% non-condensing; floor loading: ≥5 kN/m²; dedicated 220 VAC ±10%, 50 Hz, 16 A circuit with earth ground resistance <4 Ω.
