Tuofeng TFW-190 Microcomputer-Controlled Electronic Universal Testing Machine

Overview

The Tuofeng TFW-190 Microcomputer-Controlled Electronic Universal Testing Machine is a high-precision, servo-driven mechanical testing system engineered for static tensile, compressive, flexural, shear, tear, peel, and burst testing of metallic, polymeric, ceramic, composite, and elastomeric materials. It operates on the principle of controlled displacement and force feedback via closed-loop servo control, enabling accurate application of load while simultaneously capturing real-time mechanical response parameters. Designed in strict compliance with ISO 7500-1 (Class 0.5 accuracy), ASTM E4, ASTM E8/E8M, ASTM D638, ASTM D790, ISO 6892-1, ISO 178, and GB/T 16491–2008, the TFW-190 supports full traceability and audit readiness for GLP, GMP, and ISO/IEC 17025-accredited laboratories. Its robust architecture integrates high-rigidity frame construction, precision-ground ball screws, and low-backlash gear reduction to minimize mechanical hysteresis and ensure long-term repeatability (<0.2% RSD across 100+ replicate tests under identical conditions).

Key Features

• Class 0.5 force measurement accuracy per ISO 7500-1, validated across 0.2–100% of full scale (190 kN)
• Constant-resolution force transduction at 1 part in ±500,000 full-scale codes—no auto-ranging required
• Infinitely variable crosshead speed from 0.001 to 500 mm/min, programmable in 0.001 mm/min increments
• Dual-speed motorized crosshead with jog control and programmable return-to-start functionality
• Integrated electronic limit switches, emergency stop circuitry, and hardware-based overload cutoff at 110% of rated capacity
• Modular extensometry support: compatible with clip-on axial extensometers (ASTM E83 Class B1/B2) and non-contact video extensometers (optional)
• Thermally stable load cell design with temperature compensation over 10–40 °C ambient range
• CE-marked electrical safety architecture compliant with IEC 61000-6-2/6-4 EMC standards

Sample Compatibility & Compliance

The TFW-190 accommodates specimens ranging from miniature coupons (e.g., ASTM E345 foil strips) to structural components (e.g., reinforced concrete prisms per ASTM C39). Standard test widths up to 600 mm support flat, round, and irregular geometries; custom fixtures—including wedge-action grips, pneumatic clamps, four-point bend fixtures, and environmental chamber adapters—are available upon request. The system satisfies mandatory regulatory requirements for mechanical testing in regulated industries: it enables full compliance with FDA 21 CFR Part 11 when paired with audit-trail-enabled software configuration (optional), supports USP mechanical testing protocols for pharmaceutical packaging, and meets JJG 475–2008 verification procedures for national metrological accreditation in China. Calibration certificates are traceable to NIM (National Institute of Metrology, China) or NIST-equivalent reference standards.

Software & Data Management

The bundled Windows-based TFW-TestSuite v5.2 offers multi-language UI (English, Simplified/Traditional Chinese), SI/imperial unit conversion, and configurable test method templates aligned with ASTM, ISO, GB, DIN, and JIS standards. Real-time plotting includes stress–strain, load–displacement, load–time, strain–time, and dual-curve overlays. All raw data (force, displacement, time, extensometer signals) are logged at ≥1 kHz sampling rate and stored in open-format CSV and XML files. Software features include automatic parameter derivation (UTS, YS, E-modulus, % elongation, % reduction in area, tear strength, peel adhesion), statistical reporting (min/max/mean/stdev across batches), batch comparison tools, and PDF report generation with embedded digital signatures. The system supports optional 21 CFR Part 11 compliance packages including electronic signatures, audit trails, and role-based access control.

Applications

The TFW-190 serves as a primary mechanical characterization platform across R&D, QA/QC, and production environments. In aerospace, it validates tensile properties of Ti-6Al-4V sheet and carbon-fiber prepreg laminates per AMS 2750 and ASTM D3039. In automotive, it performs crash-relevant compression testing of aluminum foam cores (ISO 13314) and peel testing of adhesive bonds (ASTM D1876). In medical device manufacturing, it verifies tensile integrity of suture materials (ISO 10555-1) and balloon catheter burst pressure (ISO 10555-4). In construction, it determines compressive strength of mortar cubes (ASTM C109) and flexural modulus of fiber-reinforced polymers (ASTM D7264). Universities and national labs utilize its programmable hold-and-relax sequences for creep and stress relaxation studies under ISO 899-1/2.

FAQ

What international standards does the TFW-190 support out-of-the-box?

The system includes preloaded test methods for ASTM E8/E8M, ASTM D638, ISO 6892-1, ISO 178, GB/T 228.1, and JJG 475–2008, with additional templates downloadable via Tuofeng’s secure firmware portal.
Can the TFW-190 be integrated into an existing LIMS or MES environment?

Yes—via TCP/IP-based API (RESTful JSON endpoints) and OPC UA server option, enabling bidirectional data exchange with LabWare, Thermo Fisher SampleManager, and Siemens Opcenter.
Is third-party calibration and certification available?

Tuofeng partners with A2LA-accredited calibration providers in North America, EU, and APAC regions; factory calibration includes NIST-traceable load cell and encoder verification.
What is the warranty coverage and service response time?

Standard warranty is 24 months parts-and-labor; extended service contracts include remote diagnostics, annual performance verification, and 72-hour on-site response for critical failures under premium SLA.
Does the system support environmental testing accessories?

Yes—optional -70 °C to +300 °C chamber integration (with vacuum feedthroughs), humidity control modules (10–95% RH), and corrosion-resistant salt fog test adapters are available as OEM-configured options.
