Overview
The Tuofeng TFW-100G High-Temperature & Low-Temperature Electronic Universal Testing Machine is an integrated electromechanical system engineered for precise mechanical property evaluation of metallic, polymeric, ceramic, and composite materials under controlled thermal conditions. It combines a high-stability servo-driven universal testing frame with a thermally insulated environmental chamber capable of operation from –70 °C to +300 °C (configurable), enabling standardized tensile, compression, flexural, shear, peel, and tear testing per ISO 6892-1, ASTM E8/E21, ASTM D638/D790, and GB/T 228.1–2021. The system employs a closed-loop load control architecture based on high-fidelity strain-gauged load cells and optical encoder-based displacement feedback, ensuring traceable force application and sub-micron positional repeatability across the full temperature range.
Key Features
- Robust dual-column frame with 400 mm column spacing and 1000 mm vertical travel—optimized for specimen alignment and thermal expansion compensation;
- High-resolution displacement measurement at 0.0001 mm, synchronized with real-time load acquisition at ≥1 kHz sampling rate;
- Thermally isolated environmental chamber constructed with 304 stainless steel inner chamber and double-wall insulation; temperature uniformity ≤±1 °C across 300×250×600 mm working volume;
- Precision temperature control via PID algorithm with 0.1 °C resolution and programmable ramp/soak profiles;
- Servo motor drive system coupled to preloaded ball screws and timing belts—delivering smooth, low-vibration motion across 0.01–500 mm/min speed range;
- Integrated overload, overtravel, and emergency stop protection compliant with ISO 12100 and EN 61800-5-1 safety standards;
- Modular extensometer interface supporting clip-on, video, or laser-based strain measurement per ASTM E83 Class B-1 requirements.
Sample Compatibility & Compliance
The TFW-100G accommodates specimens up to 200 mm wide and 600 mm long within the chamber, with customizable grips (pneumatic, wedge, hydraulic) and fixture adapters for ASTM E8 round/flat bars, ISO 527 dog-bone coupons, and GB/T 1040 dumbbell specimens. All thermal and mechanical subsystems are designed for GLP/GMP-aligned environments: audit trails, user access levels, electronic signatures, and raw data immutability support FDA 21 CFR Part 11 compliance when paired with optional validated software modules. System validation documentation—including IQ/OQ protocols—is provided per client request.
Software & Data Management
Control and analysis are performed using Tuofeng’s proprietary WinTest Pro v4.x software, running natively on Windows 10/11 x64 platforms. The software supports multi-channel synchronized acquisition (load, displacement, temperature, extensometer), automated parameter calculation (UTS, YS, elongation at break, modulus, Poisson’s ratio), and export to CSV, XML, and PDF formats. All test sequences are scriptable via built-in macro language, and results are stored in encrypted SQLite databases with timestamped metadata, version history, and operator ID linkage. Raw waveform files retain full 16-bit ADC resolution for retrospective reanalysis.
Applications
This system is routinely deployed in R&D labs and QC departments for qualification of aerospace alloys (e.g., Ti-6Al-4V at 200 °C), polymer composites under cryogenic cycling (–40 °C to +80 °C), battery electrode adhesion testing, high-temperature elastomer hysteresis characterization, and thermal barrier coating bond strength assessment. Its dual-range load cell configuration (optional auto-ranging) enables seamless transition between low-force film peel tests (<10 N) and high-load structural weld evaluations (up to 200 kN), minimizing recalibration frequency and maximizing throughput.
FAQ
What temperature ranges does the environmental chamber support?
Standard configuration covers –70 °C to +300 °C; extended low-temperature options down to –100 °C and high-temperature variants up to +600 °C are available upon request.
Is the system compliant with international calibration standards?
Yes—the load cell and displacement transducers are factory-calibrated per ISO 7500-1 Class 0.5 and ISO 9513 Class 1, with NIST-traceable certificates supplied.
Can third-party extensometers be integrated?
Yes—via analog voltage (±10 V) or digital RS-422 interfaces; compatibility confirmed with ZwickRoell, MTS, and Instron extensometers.
Does the software support automated reporting per ISO/IEC 17025 requirements?
Yes—customizable report templates include uncertainty budgets, equipment calibration status, environmental condition logs, and signature fields for authorized reviewers.
What maintenance intervals are recommended for sustained accuracy?
Biannual verification of load calibration and annual thermal mapping of the chamber are advised; full system metrology service is available through Tuofeng’s global network of certified technicians.
