Yuelian YL-S70 Servo-Controlled Tensile Testing Machine

Overview

The Yuelian YL-S70 Servo-Controlled Tensile Testing Machine is a precision electromechanical testing system engineered for high-reproducibility mechanical property evaluation of materials and components across R&D, quality assurance, and production environments. Based on closed-loop servo motor actuation coupled with high-resolution ball-screw transmission, the YL-S70 implements standardized uniaxial force-displacement measurement per ISO 527, ASTM D638, GB/T 1040, and related tensile, compressive, flexural, peel, shear, puncture, and cyclic loading protocols. Its architecture integrates real-time load cell feedback, sub-micron displacement tracking, and deterministic motion control—enabling accurate quantification of yield strength, ultimate tensile strength, elongation at break, modulus of elasticity, and energy absorption characteristics under static or dynamic regimes.

Key Features

• High-fidelity dual-range load cell options (10 N to 5 kN), supporting rapid interchange without recalibration
• True closed-loop servo control with 2000 Hz sampling rate and 1/500,000 full-scale resolution in both force and displacement channels
• Adjustable crosshead speed from 0.001 mm/min (ultra-low creep testing) to 500 mm/min (high-speed peel or impact simulation)
• Modular quick-release fixture interface compatible with standardized grips (pneumatic, wedge, vise, peel, puncture, bending jigs)
• Robust mechanical design: anodized aluminum linear guides, precision-ground ball screws, ABS-coated structural housing, and integrated over-travel/overload hardware protection
• Dedicated micro-adjustment switches for fine-tuning upper/lower crosshead positioning prior to test initiation
• Comprehensive safety architecture including emergency stop, programmable upper/lower limit stops, automatic rupture detection, and real-time overload shutdown

Sample Compatibility & Compliance

The YL-S70 accommodates a broad spectrum of specimen geometries and material classes—including polymer films, adhesive tapes, composite laminates, elastomeric foams, textile fibers, pharmaceutical blister packs, shoe soles, corrugated cardboard, and biomedical sutures. Its test space (Ø140 mm diameter × 450 mm vertical stroke) supports standard and custom fixtures per ISO 2285 (peel adhesion), ISO 11339 (adhesive bond strength), ASTM D903 (peel resistance), ASTM D1876 (T-peel), and GB/T 2792 (180° peel). All firmware and software modules comply with GLP documentation requirements; audit trails, user access control, and electronic signature support align with FDA 21 CFR Part 11 readiness for regulated laboratories.

Software & Data Management

The embedded Windows-based testing software provides full method scripting, multi-curve overlay, statistical post-processing, and export-ready reporting. Users define up to seven independent test segments within a single protocol—each with distinct control modes (constant rate, constant load, constant strain, ramp-hold, cyclic waveform). The system records synchronized force–displacement, force–time, displacement–time, and stress–strain curves in real time, with interactive zoom, crosshair cursor, manual point capture (up to 40 points), and auto-sampling (up to 120 points per curve). Statistical outputs include mean, median, standard deviation, CPK, max/min values, and trimmed averages. Raw data exports to CSV, Excel, or PDF; historical datasets are indexed by operator, date, material ID, and test method for traceability and trend analysis.

Applications

• Peel strength validation of pressure-sensitive adhesives (PSA) per ASTM D3330 and ISO 8510-2
• Tensile characterization of thin films, nonwovens, and flexible packaging substrates
• Compression testing of polyurethane foams and elastomeric gaskets under ISO 3386-1
• Three- and four-point bending of rigid plastics and composites per ISO 178
• Cyclic fatigue assessment of springs, medical tubing, and wearable device components
• Puncture resistance of footwear uppers, protective gloves, and barrier membranes
• Constant-load hold tests for carton compression (ECT), seal integrity, and hot-tack performance

FAQ

What standards does the YL-S70 support out-of-the-box?
The system includes pre-configured test methods aligned with GB/T 2792, ASTM D638, ASTM D3330, ISO 527, ISO 11339, and EN 13130-1. Custom method development is supported via scriptable control logic.
Can the YL-S70 perform multi-step cyclic testing?
Yes—its software supports nested loop structures with programmable dwell times, reversal triggers, and amplitude modulation for fatigue, hysteresis, and relaxation studies.
Is calibration traceable to national metrology institutes?
Load cells are factory-calibrated using NIST-traceable reference standards; optional annual recalibration services include ISO/IEC 17025-compliant certificates.
Does the system meet regulatory requirements for pharmaceutical or medical device QA?
With enabled audit trail logging, role-based permissions, and electronic signature functionality, the YL-S70 satisfies core elements of FDA 21 CFR Part 11 and EU Annex 11 for computerized system validation.
What accessories are required for peel testing?
A 180° peel fixture (standard), specimen clamps with adjustable jaw width, and alignment guide are included; optional T-peel and floating roller fixtures are available separately.
