Tuofeng TFW-11 100 kN Electromechanical Universal Testing Machine

Overview

The Tuofeng TFW-11 is a high-precision electromechanical universal testing machine engineered for static mechanical characterization of metallic, polymeric, ceramic, composite, and elastomeric materials under uniaxial loading conditions. It operates on the principle of controlled displacement or load application via a closed-loop servo-controlled actuation system, enabling precise execution of tension, compression, bending, shear, peel, tear, and puncture tests per internationally recognized standards. Designed to meet ISO 7500-1:2018 (static calibration of force-proving instruments) and ASTM E4-23 (load verification of testing machines), the TFW-11 delivers traceable, repeatable, and reproducible results essential for R&D laboratories, quality control departments, and third-party certification bodies. Its rigid dual-column frame, preloaded ball-screw transmission, and high-resolution force/position feedback architecture ensure minimal compliance error and excellent long-term stability—critical for evaluating modulus, yield behavior, ductility, and fracture mechanics parameters.

Key Features

• ISO 7500-1 Class 0.5 certified force measurement system with ±0.005% of reading accuracy across the full 100 kN range, eliminating range-switching artifacts
• True single-range load cell resolution of 1:500,000, maintaining consistent sensitivity from 20 N to 100 kN
• Dual-speed motorized crosshead with programmable rapid approach and fine positioning modes for efficient specimen alignment and test initiation
• Integrated safety architecture including hardware-based emergency stop, electronic overtravel limits, and automatic overload shutdown at 110% of full scale
• Modular extensometry support: compatible with clip-on axial extensometers (ASTM E83 Class B-1), video extensometers, and large-deformation sensors for strain-sensitive applications
• Thermally stable cast-iron base and reinforced steel columns minimize thermal drift and mechanical resonance during low-speed creep or relaxation tests

Sample Compatibility & Compliance

The TFW-11 accommodates specimens up to 600 mm wide and 800 mm in active stroke, supporting standardized test geometries per ASTM D638 (tensile plastics), ASTM D3039 (composite tensile), ISO 6892-1 (metal tensile), ASTM C39 (concrete compression), and ISO 178 (flexural testing). Its modular fixture interface allows rapid interchange of wedge-action grips, compression platens, bend fixtures, peel jigs, and custom tooling—enabling seamless transition between material classes without recalibration. The system complies with GB/T 16491–2008 (Chinese national standard for UTM design), JJG 475–2008 (verification regulation), and meets requirements for GLP/GMP environments when paired with audit-trail-enabled software configurations. Full traceability is ensured through factory calibration certificates accredited to ISO/IEC 17025.

Software & Data Management

The Windows-based testing software provides ISO 17025-aligned data integrity features, including user-level access control, electronic signatures, and full audit trail logging compliant with FDA 21 CFR Part 11 (when configured with optional validation package). It supports multiple test modes—force-controlled, displacement-controlled, strain-controlled, and hold protocols—with real-time display of up to four synchronized curves (e.g., stress–strain, load–time, displacement–time). All calculations—including tensile strength, yield point (0.2% offset), Young’s modulus, elongation at break, compressive strength, flexural modulus, and peel adhesion—are performed automatically using standardized algorithms per ASTM E111, ISO 527, or EN 13924. Raw data exports to CSV, Excel, or XML formats; reports are customizable and include metadata (operator ID, environmental conditions, calibration status) for regulatory submissions.

Applications

The TFW-11 serves as a core mechanical characterization platform across industrial and academic sectors. In aerospace, it validates titanium alloy sheet formability and carbon-fiber laminate interlaminar shear strength. In automotive R&D, it quantifies weld joint integrity in high-strength steels and creep resistance of thermoplastic composites under simulated service temperatures. Within medical device manufacturing, it verifies tensile properties of nitinol stents and suture breaking strength per ISO 13485 requirements. Construction labs use it for compressive testing of grouts and bond strength evaluation of adhesive systems. Universities employ it for fundamental studies in viscoelasticity, fracture toughness (via ASTM E399-compliant pre-cracked specimens), and multi-axial failure criteria development.

FAQ

What international standards does the TFW-11 support out-of-the-box?

It natively supports test method execution and reporting for ASTM D638, D3039, E8, E9, E21, ISO 6892-1, 527, 178, 14129, GB/T 228.1, and JIS Z2241—with parameter presets, calculation templates, and report layouts preconfigured for each standard.

Can the system be integrated into an existing LIMS or MES environment?

Yes—via OPC UA or TCP/IP API interfaces, the controller supports bidirectional communication with laboratory information management systems (LIMS) and manufacturing execution systems (MES) for automated job dispatch, result ingestion, and equipment status monitoring.

Is third-party calibration and ISO/IEC 17025 accreditation available?

Tuofeng partners with ILAC-accredited calibration laboratories to provide on-site or depot-based recalibration services with full uncertainty budgets and traceable certificates aligned to ISO/IEC 17025:2017.

What is the warranty coverage and service response time?

Standard warranty covers parts and labor for 24 months; extended service agreements include remote diagnostics, annual preventive maintenance, and guaranteed 48-hour onsite technician dispatch for critical failures within major industrial zones.
