Tuofeng TFL-33S Desktop Electromechanical Tensile Testing Machine

Overview

The Tuofeng TFL-33S Desktop Electromechanical Tensile Testing Machine is a precision-engineered, microprocessor-controlled universal testing system designed for static mechanical property evaluation of low-to-medium strength materials in R&D laboratories, QC/QA departments, and academic institutions. Based on the fundamental principle of uniaxial force application under controlled displacement or load rate, the system applies calibrated tensile, peel, tear, or flexural loads to specimens while continuously measuring force (via high-stability load cell) and displacement (via optical encoder). Its rigid C-frame architecture, coupled with a brushless DC servo motor drive and precision ball-screw transmission, ensures high repeatability (<±0.5% force error), minimal thermal drift, and long-term stability—critical for compliance-driven environments requiring traceable, auditable data.

Key Features

• Electromechanical actuation with 0.01–500 mm/min infinitely variable speed control, enabling precise strain-rate-dependent testing per ISO 527, ASTM D638, and GB/T 1040 standards.
• Integrated 5 kN load cell with 0.5-class accuracy (±0.5% of reading) and internal resolution of 1/300,000 full-scale codes—no range switching required across the entire 0.4%–100% FS operating window.
• 700 mm vertical crosshead travel, expandable upon request; equipped with dual-mode positioning (manual jog + programmable auto-return) and three-speed motorized table lift (fast/medium/slow).
• Comprehensive hardware safety suite: electronic limit switches, emergency stop circuit, overload protection (>110% FS), and software-enforced operational boundaries.
• Modular fixture interface supporting standardized grips (pneumatic, wedge, vise-type), peel jigs, tear fixtures, and custom adapters for wires, films, fibers, adhesives, and biomedical substrates.

Sample Compatibility & Compliance

The TFL-33S accommodates specimens ranging from fine metallic wires (diameter ≥0.1 mm) and polymer films (thickness ≤2 mm) to textile yarns, paperboard laminates, and thermoplastic elastomer strips. It supports standardized test geometries per ISO 527-2 (tensile bars), ASTM D882 (thin plastics), ASTM D903 (peel), ASTM D1876 (T-peel), and GB/T 2792 (adhesive tape peel). All force and displacement measurements are traceable to national metrological standards. The system meets mechanical safety requirements per ISO 12100 and electrical safety per IEC 61000-6-2/6-4. When configured with audit-trail-enabled software and user access controls, it supports GLP/GMP-aligned workflows compliant with FDA 21 CFR Part 11 Annex 11 expectations for electronic records and signatures.

Software & Data Management

The Windows-based TensileTest Pro™ software (XP/Vista/7/10 compatible) provides full test configuration, real-time monitoring, and post-processing capabilities. Users may select control modes—including constant rate of extension (CRE), constant load ramping, or displacement targeting—and define multi-step test profiles. Real-time plots include load–time, load–displacement, stress–strain, and extension–time curves, all simultaneously viewable and exportable in CSV, XML, or PDF. Automatic calculation of tensile strength, yield point, modulus (secant/tangent), elongation at break, peel strength, and tear resistance is performed upon test completion using user-input specimen geometry (width, thickness, gauge length). Data management includes hierarchical project folders, timestamped audit logs, password-protected user roles (admin/operator/viewer), and optional SQL database integration for enterprise-level LIMS compatibility. Software updates are provided free of charge for the instrument’s service life.

Applications

• Mechanical characterization of polymeric films and packaging materials (e.g., seal strength, puncture resistance, dart impact correlation).
• Quality verification of wire harness terminations, crimp joints, and PCB solder bonds per IPC-J-STD-001 and MIL-STD-202.
• R&D of biodegradable films, hydrogels, and soft tissue simulants under quasi-static loading conditions.
• Adhesion performance assessment of pressure-sensitive tapes, medical transdermal patches, and laminated composites.
• Educational use in materials science curricula for hands-on demonstration of Hooke’s law, plastic deformation, necking, and fracture mechanics fundamentals.

FAQ

What standards does the TFL-33S support out of the box?

It natively implements test method templates for ASTM D638, D882, D903, ISO 527, ISO 1133, GB/T 1040, and GB/T 2792. Custom protocol scripting is available via API.
Can the system be integrated into an existing LIMS or MES environment?

Yes—through configurable OPC UA or TCP/IP socket interfaces, raw data streams and summary reports can be transmitted to external systems without middleware.
Is calibration certification included with shipment?

Each unit ships with a factory calibration certificate (traceable to CNAS-accredited standards) valid for 12 months. On-site recalibration services and ISO/IEC 17025-compliant certificates are available upon request.
What is the warranty coverage and service response time?

Standard 24-month parts-and-labor warranty; technical support is available via remote diagnostics during business hours (GMT+8), with on-site service dispatched within 5 business days for critical failures.
Does the software support multi-language operation and regulatory audit trails?

Yes—UI language toggles between English, Simplified Chinese, Traditional Chinese, and Spanish. Audit trail logging (user actions, parameter changes, test executions) complies with ALCOA+ principles and is exportable as tamper-evident PDF.
