Hengyi HY-0580ETH Single-Arm Universal Testing Machine for Release Liner Peel Strength Testing

Overview

The Hengyi HY-0580ETH is a precision-engineered single-arm universal testing machine designed specifically for peel strength evaluation of release liners—critical functional films used in pressure-sensitive adhesives, labels, medical tapes, and electronic die-cutting applications. Built upon a rigid single-column load frame with high-stiffness aluminum alloy construction, the system delivers stable axial alignment and minimal deflection during low-force, high-resolution peel tests (down to 1 N full scale). Its modular architecture supports interchangeable load cells (1 N to 5000 N), enabling traceable force measurement across multiple orders of magnitude without mechanical recalibration. The instrument operates on fundamental principles of uniaxial tensile mechanics per ASTM D903, ISO 8510-2, and GB/T 2792, applying controlled displacement or constant-rate peeling at standardized angles (typically 90° or 180°) while recording real-time force-displacement data. All mechanical and control subsystems comply with metrological requirements defined in GB/T 16491-2008 (equivalent to ISO 7500-1 Class 0.5), ensuring repeatability ≤ ±0.5% and long-term stability under laboratory or production QC environments.

Key Features

• Single-column, compact footprint design (470 × 400 × 1510 mm) optimized for benchtop integration in constrained lab spaces
• High-resolution force sensing: 500,000-count A/D conversion with no internal range switching—maintains consistent resolution across entire 1 N–5000 N span
• Wide dynamic speed range: 0.001–500 mm/min, programmable in 0.001 mm/min increments; velocity accuracy ±0.5% of setpoint per GB/T 16852.1-2008
• Dual-mode motion control: supports both displacement-controlled (for peel angle consistency) and force-controlled (for creep or relaxation protocols) test profiles
• Integrated safety architecture: electronic upper/lower limit switches, hardware-based overload cutoff (>110% FS), and real-time self-diagnostic monitoring of drive current, voltage, and thermal load
• Modular fixture interface: standardized T-slot base plate compatible with ISO 2041-compliant peel jigs (90° and 180° configurations), tensile grips, and custom tooling for non-standard substrates
• Intuitive local operation: tactile keypad with LED status display; optional PC-based control via USB 2.0 or Ethernet

Sample Compatibility & Compliance

The HY-0580ETH accommodates release liners laminated onto silicone-coated PET, fluoropolymer, or paper carriers, as well as thin-film substrates such as polyimide, polyester, and acrylic PSA layers. Specimen widths up to 120 mm fit within the effective test width, while 800 mm vertical stroke enables full-length peel assessment of extended samples. The system meets mandatory regulatory benchmarks including GB/T 2611-2007 (General Technical Requirements for Testing Machines), GB/T 16491-2008 (Electronic UTM Performance Verification), and ISO 7500-1:2018 (Static Calibration of Force-Measuring Systems). When configured with audit-trail-enabled software and calibrated load cells traceable to NIM (National Institute of Metrology, China), it satisfies GLP-compliant documentation requirements for pharmaceutical packaging validation (per USP ) and automotive adhesive qualification (SAE J2248).

Software & Data Management

Bundled HengyiTest v3.2 software provides ISO/IEC 17025-aligned test sequencing, real-time curve overlay, and automated pass/fail logic based on user-defined limits (e.g., average peel force, maximum peak, residual adhesion). Raw data export is available in CSV, XML, and PDF formats—including embedded metadata (operator ID, calibration date, environmental conditions). The software supports 21 CFR Part 11 compliance packages with role-based access control, electronic signatures, and immutable audit trails for all method modifications and result approvals. Custom test templates can be built using drag-and-drop scripting for multi-step protocols (e.g., pre-load dwell → ramp → peel → post-test hold), and third-party integration is supported via TCP/IP API for MES or LIMS synchronization.

Applications

• Quantitative peel strength verification of silicone-release coatings on label facestocks
• Adhesion durability assessment of medical-grade release liners under accelerated aging (ISO 10993-12)
• Comparative analysis of low-tack vs. high-tack liner systems for electronics manufacturing (e.g., flex circuit masking)
• Quality conformance testing per ASTM D3330 (Pressure-Sensitive Tape Peel Adhesion) and JIS Z 1522
• Material development support for biodegradable release films (PLA, cellulose derivatives) requiring sub-10 N force resolution
• Root-cause investigation of liner delamination in roll-to-roll converting processes

FAQ

What peel angles does the HY-0580ETH support?

The system is mechanically compatible with both 90° and 180° peel fixtures; angle selection is determined by fixture geometry—not machine firmware.
Can I use this tester for tensile testing of thin films beyond peel applications?

Yes—the same load frame and control architecture support ASTM D882-compliant tensile testing of films, foils, and nonwovens when equipped with pneumatic or mechanical wedge grips.
Is calibration certification included with shipment?

Each unit ships with a factory calibration report traceable to NIM standards; accredited third-party calibration (ISO/IEC 17025) is available as an optional service.
How is data integrity ensured during long-duration peel tests?

The controller employs dual-buffered memory with automatic failover—data continues recording to internal flash storage even if PC connection is interrupted.
Does the system meet FDA requirements for medical device packaging validation?

When deployed with validated software, documented IQ/OQ protocols, and GMP-aligned SOPs, the HY-0580ETH fulfills technical prerequisites for peel strength testing in ISO 11607-2 submissions.
