Yuelian YL-S70 Servo-Controlled Peel and Tensile Testing Machine

Overview

The Yuelian YL-S70 Servo-Controlled Peel and Tensile Testing Machine is a high-precision electromechanical universal testing system engineered for static mechanical characterization of materials and components across research laboratories, quality control departments, and manufacturing environments. Based on closed-loop servo control architecture and precision ball-screw actuation, the YL-S70 implements standardized quasi-static loading protocols in accordance with ISO 6892-1, ASTM E8/E21, GB/T 228.1, and GB/T 2792 (for peel strength). It delivers traceable force-displacement-time data under controlled displacement or load-rate conditions, supporting both uniaxial tensile/compression and specialized modes including peel, tear, puncture, bend (3-point & 4-point), shear, and cyclic loading. Its modular design enables rapid reconfiguration for diverse specimen geometries and test standards without hardware recalibration.

Key Features

• AC servo motor drive with real-time torque-current feedback, ensuring smooth, low-noise motion and consistent speed fidelity across the full 0.001–500 mm/min range
• Precision ground ball screw transmission with aluminum alloy protective shroud (sandblasted + anodized finish) for long-term dimensional stability and contamination resistance
• High-resolution force transducer with bidirectional sensing capability and auto-zeroing function—supports seamless transition between tension and compression tests
• Ultra-fine displacement resolution of 1/500,000 mm and force resolution of 1/500,000 FS, enabling detection of micro-yield events and subtle viscoelastic transitions
• Real-time multi-curve display: simultaneous visualization of force vs. displacement, force vs. time, displacement vs. time, and stress vs. strain—with dynamic zoom, pan, crosshair cursor, and point extraction tools
• Advanced test sequencing engine supporting up to 120 automatic data points per test, 40 manual markers, and 7 user-defined analysis intervals per curve
• Comprehensive statistical post-processing: calculation of ultimate tensile strength (UTS), yield strength (0.2% offset), elongation at break, modulus of elasticity, fracture energy, CPK, standard deviation, median, and trimmed mean
• Configurable safety logic: overload shutdown, emergency stop button, specimen rupture auto-stop, upper/lower limit position triggers, over-travel protection, and over-capacity cut-off

Sample Compatibility & Compliance

The YL-S70 accommodates a broad spectrum of material forms—including films, foams, adhesives, textiles, composites, elastomers, paperboard, medical packaging, footwear components, and polymer laminates—via interchangeable fixtures (tensile grips, peel jigs, puncture probes, bend supports, compression platens). All mechanical test routines adhere to internationally recognized standards: peel testing per ASTM D903, ISO 8510-2, and GB/T 2792; tensile testing per ISO 527, ASTM D638, and GB/T 1040; compression per ISO 7500-1 and ASTM E9; and flexural testing per ISO 178 and ASTM D790. The system’s hardware architecture and software logging meet foundational requirements for GLP-compliant environments, with timestamped audit trails, operator ID tagging, and raw data export in CSV and XML formats compatible with LIMS integration.

Software & Data Management

Bundled YL-TestSuite v3.x software provides a validated Windows-based interface compliant with FDA 21 CFR Part 11 principles for electronic records and signatures (user authentication, role-based access, immutable audit logs, electronic signature capture). It supports method templates aligned with ISO/IEC 17025 documentation practices, including calibration certificate import, environmental condition logging (optional sensor inputs), and automated report generation in PDF or Excel with embedded test curves and statistical summaries. Raw data files retain full 2000-Hz acquisition fidelity and are stored in open-format binary containers for third-party analysis (e.g., MATLAB, Python Pandas). Software permits batch comparison of historical datasets—overlaying up to eight curves with synchronized axes—and exports annotated graphics in SVG, PNG, or EMF formats for inclusion in technical reports or regulatory submissions.

Applications

• Adhesion strength evaluation of pressure-sensitive tapes, labels, and laminated packaging structures
• Mechanical validation of biomedical device materials (catheter tubing, suture anchors, wound dressings)
• Quality assurance of automotive interior trim, gaskets, and acoustic foams under compression set and creep conditions
• Performance benchmarking of textile reinforcements used in composite layup processes
• Regulatory compliance testing for food-grade flexible packaging per FDA 21 CFR 177 and EU 10/2011 migration protocols
• R&D of sustainable biopolymers—including PLA, PHA, and starch blends—under controlled humidity and temperature (when integrated with environmental chamber)
• Structural integrity verification of consumer electronics housings, battery enclosures, and connector retention forces

FAQ

What standards does the YL-S70 support out-of-the-box?
The system includes preconfigured test methods for ASTM D903 (peel), ASTM D638 (tensile), ISO 6892-1 (metal tensile), GB/T 2792 (Chinese peel standard), and ISO 179 (impact-modified plastics bending), with editable parameters to accommodate lab-specific deviations.
Can the YL-S70 perform cyclic fatigue testing?
Yes—its programmable multi-step control allows definition of amplitude, frequency, dwell time, and termination criteria for displacement-controlled or load-controlled sinusoidal, triangular, or trapezoidal waveforms, supporting up to 1 million cycles per sequence.
Is calibration traceability provided?
Each unit ships with a factory calibration certificate traceable to CNAS-accredited national metrology institutes (e.g., GIMT, SCMC), covering force, displacement, and speed channels; annual recalibration services are available via authorized service centers.
Does the system require external computing hardware?
No—the included software runs natively on Windows 10/11 PCs; however, users may supply their own certified workstation meeting minimum specs (Intel i5, 8 GB RAM, SSD, USB 2.0/3.0 port) if preferred.
How is mechanical overload protection implemented?
Hardware-level current-limiting circuits monitor servo motor torque in real time; combined with software-defined force thresholds and physical end-stop switches, this ensures immediate power cutoff within <10 ms upon exceeding preset limits.
