Overview
The Yuelian YL-S70 Servo-Controlled Universal Testing Machine is an electromechanical materials testing system engineered for precision mechanical property evaluation under uniaxial loading conditions. Based on closed-loop servo motor control and high-resolution ball-screw actuation, it implements force-, displacement-, and strain-controlled test modes in accordance with internationally recognized standards including GB/T 2792 (peel adhesion), GB/T 1040 (tensile properties of plastics), GB/T 9341 (flexural properties), ISO 527, ISO 178, ASTM D638, ASTM D790, ASTM D1876 (T-peel), and ASTM D3330 (adhesive peel strength). The system delivers repeatable, traceable, and auditable mechanical data across tension, compression, bending (3-point and 4-point), shear, tear, peel, puncture, cyclic fatigue, and creep-hold protocols — supporting both R&D validation and routine QC/QA workflows in polymer, packaging, automotive component, medical device, and paper & board laboratories.
Key Features
- High-fidelity servo motor drive coupled with preloaded precision ground ball screw transmission, ensuring minimal backlash and long-term positional stability
- Modular quick-change fixture interface enabling tool-free swapping of grips, bend fixtures, peel jigs, puncture probes, and compression platens
- Dual-range load cell configuration support (e.g., 10 N / 5 kN), facilitating seamless transition between micro-force and macro-force testing without recalibration
- Real-time multi-curve visualization: simultaneous display of Force–Displacement, Force–Time, Displacement–Time, and Stress–Strain plots with dynamic scaling, crosshair cursor, point extraction, and overlay comparison
- Advanced test sequencing engine supporting nested multi-step control: constant rate, target load/displacement/stress/strain, ramp-hold cycles, auto-return, fracture detection, and zero-reset logic
- Comprehensive hardware safety architecture: dual-limit switch protection, overload cutoff, emergency stop button, software-defined upper/lower bounds, and automatic halt upon specimen failure
- Robust industrial enclosure: anodized aluminum beam housing, ABS structural casing with electrostatic powder coating, and integrated micro-adjustment travel controls
Sample Compatibility & Compliance
The YL-S70 accommodates specimens ranging from thin films (≥25 µm) to rigid molded parts (≤140 mm width × 450 mm effective stroke). Its modular grip systems support pneumatic, wedge, vise, pin, and custom-designed fixtures compliant with ISO 2041 and ASTM E8/E9 mounting geometries. All test methods are programmable to meet GLP/GMP documentation requirements, with audit-trail-enabled test logs, user access control, electronic signatures, and 21 CFR Part 11-ready data export formats (CSV, XML, PDF). Calibration certificates per ISO/IEC 17025 are available upon request.
Software & Data Management
The embedded Windows-based control software provides full test method definition, real-time data acquisition at 2,000 Hz, and post-test statistical analysis. It supports up to 120 automated data points per test, 40 manual annotations, and 7 definable measurement intervals. Statistical outputs include maximum, minimum, mean, trimmed mean (excluding top/bottom 5%), median, standard deviation, population SD, and process capability index (CpK). Historical datasets can be recalled and overlaid for comparative trend analysis. Export options include raw time-series arrays, summary reports with pass/fail flags, and graphical exports compatible with LIMS integration.
Applications
- Tensile strength and elongation at break of thermoplastics, elastomers, composites, and nonwovens
- Peel adhesion testing of pressure-sensitive tapes, labels, and laminated packaging per GB/T 2792 and ASTM D3330
- Flexural modulus and yield stress determination in rigid polymers using 3- or 4-point bending fixtures
- Puncture resistance of medical gowns, surgical drapes, and foam cushioning materials
- Cyclic compression endurance of polyurethane foams and rubber isolators (up to 100,000 cycles)
- Shear strength of adhesive bonds and laminated substrates per ASTM D1002
- Compression testing of corrugated cardboard boxes (edge crush test simulation) and honeycomb cores
FAQ
What standards does the YL-S70 support out-of-the-box?
Preconfigured test templates cover GB/T 2792, GB/T 1040, GB/T 9341, ISO 527, ISO 178, ASTM D638, ASTM D790, ASTM D1876, and ASTM D3330.
Can the system perform closed-loop strain control?
Yes — when paired with optional extensometers or digital image correlation (DIC) modules, the controller supports true strain-rate and strain-targeted control per ISO 527-2 Annex A.
Is the software compliant with FDA 21 CFR Part 11?
The software includes electronic signature capability, audit trail logging, role-based access control, and secure data export — meeting core technical requirements for Part 11 compliance in regulated environments.
What is the maximum test speed and resolution?
Speed range: 0.001–500 mm/min (customizable beyond); position resolution: 0.000002 mm (1/500,000 of full scale); force resolution: 1/500,000 of selected capacity.
Does the system support automated reporting?
Yes — customizable report templates generate PDF or Excel outputs with embedded graphs, statistics, pass/fail indicators, and metadata (operator ID, timestamp, calibration status, environmental conditions).
