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

Overview

The Yuelian YL-S70 is a servo-controlled electromechanical tensile and peel testing machine engineered for precision mechanical property evaluation across diverse material classes. It operates on the principle of controlled uniaxial force application via a high-resolution ball screw-driven crosshead, enabling accurate measurement of tensile strength, elongation at break, compressive yield, peel adhesion (e.g., ASTM D903, ISO 8510-2), shear bond strength, tear resistance (ASTM D624), and delamination behavior in laminates and coated substrates. Designed for compliance with international standard test methods—including ASTM D3330, D1876 (T-peel), D412 (rubber tensile), ISO 527 (plastics), ISO 11339 (adhesive peel), and GB/T 2792 (Chinese national standard for peel strength)—the system delivers traceable, repeatable results suitable for QC laboratories, R&D departments, and contract testing facilities operating under GLP or ISO/IEC 17025 frameworks.

Key Features

• AC servo motor drive with synchronized timing belt and ground-precision ball screw transmission ensures smooth, low-backlash motion and long-term mechanical stability.
• Programmable crosshead speed range from 0.01 to 1000 mm/min supports both quasi-static characterization and dynamic rate-dependent response analysis.
• High-fidelity load cell with 1/250,000 internal resolution and ±0.5% full-scale accuracy meets ISO 7500-1 Class 0.5 and ASTM E4 calibration requirements.
• Displacement resolution of 0.005 mm and stroke capability up to 600 mm (extendable to 800 mm per configuration) accommodate standard and non-standard specimen geometries.
• Integrated safety architecture includes overload cutoff, emergency stop button, automatic halt upon specimen rupture, programmable upper/lower travel limits, and auto-return-to-initial-position functionality.
• Modular grip interface supports quick-change configurations—flat-faced, pneumatic, wedge, roller, and custom fixtures—for metals, elastomers, films, composites, and biomedical substrates.

Sample Compatibility & Compliance

The YL-S70 accommodates specimens ranging from thin polymer films (≥12 µm) and pressure-sensitive adhesives (PSAs) to metallic foils, textile yarns, leather strips, paperboard laminates, and thermoplastic composites. Its open-frame design allows for easy insertion and alignment of irregular or oversized samples up to Ø140 mm in width. All test protocols align with regulatory expectations for documented test method validation: built-in unit conversion (N, kN, kgf, lbf, MPa), real-time curve plotting, and audit-ready data export satisfy FDA 21 CFR Part 11 requirements when paired with validated software. The system is routinely deployed in environments requiring adherence to ISO 9001, IATF 16949, and RoHS-compliant manufacturing workflows.

Software & Data Management

Control and analysis are executed through Yuelian’s proprietary Windows-based software suite, compatible with Windows 10/11 (64-bit). The interface supports multi-step test sequences, real-time stress–strain visualization, automatic peak detection, modulus calculation (secant/tangent), and statistical reporting (mean, SD, CV%, min/max). Raw data exports to CSV, Excel, or PDF formats; batch processing enables comparative analysis across material lots or process conditions. Software logs include operator ID, timestamp, environmental metadata (optional via external sensor integration), and digital signature fields—facilitating GMP/GLP-compliant documentation. USB 2.0 connectivity ensures plug-and-play operation without additional drivers.

Applications

• Peel strength verification of medical device packaging (ISO 8553) and sterile barrier systems.
• Tensile property mapping of biodegradable films used in food packaging and agricultural mulch.
• Adhesive bond integrity assessment in automotive interior trim assemblies and EV battery module laminates.
• Mechanical screening of recycled PET fibers, nonwovens, and geotextiles per ASTM D4595.
• Quality conformance testing of printed circuit board (PCB) solder mask adhesion and flexible substrate delamination resistance.
• Evaluation of textile seam strength, leather grain layer cohesion, and rubber vulcanization consistency.

FAQ

What standards does the YL-S70 support out-of-the-box?
The system is pre-configured with test templates aligned to ASTM D903, D1876, D3330, ISO 8510-2, ISO 527-1, GB/T 2792, and GB/T 1040 series—custom method creation is supported via scriptable test parameters.
Can the YL-S70 perform cyclic or fatigue testing?
While primarily designed for monotonic loading, optional firmware upgrades enable limited displacement-controlled cyclic protocols (e.g., 10–1000 cycles) with user-defined dwell times and load reversal thresholds.
Is third-party calibration certification available?
Yes—Yuelian provides NIST-traceable calibration certificates (load and displacement) issued by CNAS-accredited laboratories, valid for 12 months under standard usage conditions.
How is data integrity ensured during long-duration tests?
The embedded controller maintains independent data logging at ≥100 Hz sampling rate; power-loss recovery mode preserves all buffered measurements and resumes execution upon reboot.
What maintenance intervals are recommended?
Ball screw lubrication every 6 months; annual load cell recalibration and mechanical alignment verification; no consumables beyond standard grip wear parts.
