Yuelian YL-90S Electronic Tensile Testing Machine

Overview

The Yuelian YL-90S Electronic Tensile Testing Machine is a modular, microprocessor-controlled universal testing system engineered for precision mechanical characterization of materials in quality control, R&D, and incoming inspection environments. It operates on the principle of controlled uniaxial force application via a high-efficiency stepper motor–driven ball screw actuator, enabling reproducible load–displacement profiling under ASTM, ISO, and GB-compliant test protocols. Designed for static mechanical evaluation, the instrument supports tensile, compression, peel, tear, shear, and ring tack adhesion tests across heterogeneous material classes—including polymers, elastomers, thin metals, laminates, paperboard, textiles, and packaging composites. Its rigid frame architecture, 85%+ mechanical transmission efficiency, and low-inertia drive system minimize energy loss and hysteresis, ensuring high repeatability in force measurement and positional control.

Key Features

• High-resolution dual-channel acquisition: Simultaneous real-time display and logging of load (N, kgf, lbf, MPa) and displacement (mm) with 0.001 mm stroke resolution and 1/500,000 full-scale force resolution.
• Computer-integrated control: Fully programmable test speed (0.5–600 mm/min), automatic return-to-start, overload protection, specimen rupture detection, and upper/lower limit-triggered stop modes—all configurable via USB-connected host PC.
• Modular gripping interface: Quick-release couplings accommodate interchangeable fixtures—tensile jaws, peel arms, shear plates, and ring tack adapters—enabling rapid reconfiguration without tooling.
• Dual-mode operation: Standalone functionality via embedded firmware interface or full data acquisition and analysis when paired with proprietary Windows-based software supporting statistical reporting, curve overlay, modulus calculation, and pass/fail thresholding.
• Compliance-ready architecture: Built-in audit trail logging, user-access levels, and parameter lockout functions support GLP/GMP-aligned workflows; raw data export (CSV, XLSX) facilitates traceability per FDA 21 CFR Part 11 requirements when deployed with validated software configurations.

Sample Compatibility & Compliance

The YL-90S accommodates specimens up to 140 mm wide and 500 mm traversable stroke, making it suitable for standardized strip, film, foil, tape, and laminate geometries used in packaging, automotive interior trim, medical device bonding, and flexible electronics substrate qualification. It meets the mechanical test requirements of multiple international standards, including ASTM D3330 (peel adhesion of pressure-sensitive tapes), ASTM D882 (tensile properties of thin plastic sheeting), ISO 11339 (adhesive peel strength), GB/T 2792 (peel strength of pressure-sensitive adhesive tapes), GB/T 12914 (tensile testing of paper and board), and GB/T 1040 (plastics tensile testing). All calibration and verification procedures align with ISO/IEC 17025–accredited metrology practices, and force transducer certification is traceable to NIM (National Institute of Metrology, China).

Software & Data Management

The included PC software provides a calibrated, timestamped data acquisition environment compliant with laboratory documentation best practices. Users define test methods—including preload, ramp rate, hold duration, and break criteria—via intuitive graphical templates. Acquired force–displacement curves are auto-saved with metadata (operator ID, sample ID, environmental conditions, calibration date). Statistical tools compute mean, standard deviation, CV%, yield point, ultimate tensile strength, elongation at break, and secant modulus. Export options include PDF reports with embedded charts, CSV for third-party analysis (e.g., MATLAB, JMP), and XML for LIMS integration. Optional 21 CFR Part 11 add-on enables electronic signatures, change history tracking, and role-based access control—critical for regulated pharmaceutical or medical device manufacturing QC labs.

Applications

This system serves as a foundational mechanical tester in diverse industrial and academic settings: validating peel strength of medical tape adhesives per ISO 25537; assessing delamination resistance in multilayer food packaging films; quantifying bond integrity in EV battery tab welds; measuring tensile modulus of biodegradable PLA filaments for additive manufacturing; evaluating tear propagation in geotextiles per ASTM D4533; and verifying initial tack of PSA labels in ambient and accelerated aging studies. Its adaptability to small-batch, high-mix testing makes it especially valuable in contract testing labs, university materials science departments, and supplier qualification programs requiring rapid method development and cross-material comparability.

FAQ

What standards does the YL-90S support out of the box?
It natively supports test method templates for ASTM D3330, ASTM D882, GB/T 2792, GB/T 12914, and GB/T 1040. Custom method creation is enabled for non-standard or internal specifications.
Can the system perform constant-load or constant-strain-rate tests?
Yes—closed-loop control allows user-defined strain-rate profiles (e.g., 10 mm/min until 50 N, then hold for 60 s) and multi-stage cyclic loading sequences.
Is calibration certificate included with shipment?
A factory calibration report (traceable to national standards) is supplied. Optional on-site calibration by accredited third-party providers is available upon request.
What grip types are compatible beyond the standard set?
Custom-designed pneumatic, wedge-action, pin-and-slot, and floating roller grips can be integrated using the universal M6 mounting interface and provided dimensional drawings.
Does the software support automated pass/fail judgment against specification limits?
Yes—threshold-based logic triggers visual alerts and flags results during acquisition, with configurable tolerance bands and automatic annotation of out-of-spec events in exported reports.
