Tuofeng TFW-130 Microcomputer-Controlled Electromechanical Universal Tensile Testing Machine

Overview

The Tuofeng TFW-130 is a microcomputer-controlled electromechanical universal tensile testing machine engineered for high-reproducibility mechanical property evaluation of metallic, non-metallic, and composite materials. Based on servo-motor-driven precision ball-screw actuation and closed-loop load/position feedback control, the system complies with fundamental principles of uniaxial quasi-static mechanical testing per ASTM E4, ISO 7500-1, and GB/T 16491–2008. Its architecture supports standardized determination of tensile strength, yield strength (upper/lower), elongation at break, Young’s modulus, compressive strength, flexural modulus, tear resistance, peel adhesion, and puncture performance—making it suitable for R&D validation, quality assurance, and regulatory conformance testing across industrial and academic laboratories.

Key Features

• High-stiffness dual-column frame with reinforced crosshead and precision-ground ball-screw transmission system for minimal axial deflection under full-load conditions.
• Imported AC servo motor coupled with worm-gear reduction gearbox ensures smooth, low-noise operation across the full speed range (0.001–500 mm/min), with stepless speed control and programmable ramp profiles.
• Force transducer calibrated to Class 0.5 accuracy per ISO 376, delivering ±0.5% full-scale repeatability over the entire measurement range (0.2–100% FS).
• Optical encoder-based displacement measurement with 0.001 mm resolution and ±0.005% reading accuracy; compatible with optional extensometers (contact or non-contact) for strain-controlled tests per ASTM E83 or ISO 9513.
• Dual-speed motorized crosshead adjustment (fast/slow modes) with jog functionality and automatic return-to-initial-position after test completion.
• Integrated safety architecture including electronic travel limits, emergency stop circuitry, overload protection (auto-shutdown at >110% FS), and mechanical overload buffer.

Sample Compatibility & Compliance

The TFW-130 accommodates specimens up to 600 mm wide (customizable) and 1000 mm in vertical travel, supporting standardized test geometries per ASTM D638 (plastics), ASTM D412 (elastomers), ASTM B557 (metals), ISO 527, ISO 6892-1, GB/T 228.1, and JIS Z2241. Fixture options include wedge-action grips for metals, pneumatic grips for thin films, peel fixtures per ASTM D903, and compression platens compliant with ASTM C39 and ISO 7500-1. The system meets metrological requirements defined in JJG 475–2008 (Chinese verification regulation for electronic universal testing machines) and supports audit-ready documentation for GLP/GMP environments. Optional configurations enable 21 CFR Part 11-compliant user access control, electronic signatures, and immutable audit trails when paired with validated software modules.

Software & Data Management

The embedded Windows-based test software provides multi-mode control—including constant-rate loading, constant-strain-rate, load-hold, displacement-hold, and cyclic protocols. Real-time visualization includes synchronized force–time, stress–strain, force–displacement, and extension–time plots, with on-the-fly switching between display modes. Units for force (N, kN, lbf), displacement (mm, in), and stress (MPa, psi) are freely configurable. Software automatically calculates and reports standardized mechanical parameters (e.g., tensile strength, yield offset, modulus, % elongation, % reduction in area) upon test completion. Data export supports CSV, Excel, and PDF formats; batch reporting enables comparative overlay of up to 12 curves with statistical summary (max/min/mean). All raw data files are timestamped and stored with metadata (operator ID, sample ID, environmental conditions), supporting traceability and re-analysis without loss of fidelity.

Applications

The TFW-130 serves as a primary mechanical characterization platform in wire and cable manufacturing (conductor tensile integrity, insulation elongation), aerospace composites (carbon-fiber laminate interlaminar shear), automotive elastomers (hose burst strength, bushing compression set), rubber and plastic compound development (cure-state correlation, filler dispersion effects), powder metallurgy (green strength and sintered density relationships), and construction materials (rebar ductility, geotextile tensile capacity). It is routinely deployed in third-party certification labs for CE marking, UL listing, and CNAS-accredited testing per IEC 60811, EN 50363, and GB/T 12706 series standards.

FAQ

What international standards does the TFW-130 support out-of-the-box?

The base configuration conforms to ASTM E4, ISO 7500-1, GB/T 16491–2008, and JJG 475–2008. Pre-loaded test methods for ASTM D638, ISO 527, and GB/T 228.1 are included; additional method templates can be imported or customized.

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

Yes—via OPC UA or TCP/IP API interfaces, enabling bidirectional data exchange with laboratory information management systems and enterprise manufacturing execution systems.

Is calibration traceability provided with delivery?

Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China) or equivalent national metrology institute, accompanied by uncertainty budgets per ISO/IEC 17025.

What is the warranty coverage and service response time?

Standard warranty is 24 months parts-and-labor; extended service contracts include on-site preventive maintenance, remote diagnostics, and priority spare-part dispatch within 72 business hours globally.

Are custom fixtures available for specialized specimen geometries?

Yes—Tuofeng offers OEM fixture design and fabrication services based on client-provided drawings or ASTM/ISO-defined geometry specifications, with lead times typically 3–6 weeks.
