Hengyi HY-0580YUVVNN Computer-Controlled Sealing Strip Pull-Out Force Tester

Overview

The Hengyi HY-0580YUVVNN Computer-Controlled Sealing Strip Pull-Out Force Tester is a precision electromechanical universal testing system engineered for quantitative mechanical evaluation of elastomeric and polymer-based sealing components—particularly automotive and architectural glazing seals. It operates on the principle of controlled uniaxial tensile displacement, measuring the force required to disengage a standardized 100-mm sealing strip specimen from its substrate at a defined rate of 100 mm/min under ambient conditions. The system employs a single-column rigid frame architecture with high-stiffness crosshead guidance, servo-controlled AC motor drive, and real-time closed-loop feedback for force, displacement, and strain. Its modular design supports both dedicated seal pull-out testing and broader material characterization across metals, plastics, textiles, composites, and adhesives—making it suitable for R&D labs, quality assurance departments, and third-party certification bodies requiring traceable, repeatable mechanical data.

Key Features

• Single-column structural design optimized for stability, low footprint (470 × 400 × 1510 mm), and ease of integration into constrained laboratory environments.
• Interchangeable load cells spanning 1 N to 5000 N—enabling high-resolution measurement of low-force seal detachment events as well as higher-load structural validation tests.
• Full-scale force resolution of ±500,000 digital counts without range switching, ensuring consistent sensitivity across the entire measurement span.
• Precise speed control from 0.001 to 500 mm/min with ±0.5% accuracy; programmable ramp-hold-step profiles for complex loading protocols.
• Dual-mode positioning: fast manual return and automated post-test return to initial position with configurable dwell time.
• Integrated electronic limit switches and overload protection (10% above full scale) to prevent mechanical damage during operator error or specimen failure.
• Real-time diagnostic monitoring of drive voltage, current, thermal load, and sensor integrity—triggering immediate system halt upon anomaly detection.
• Compliant with ISO/IEC 17025 preconditions for test equipment validation, including traceable calibration paths per GB/T 16852.1–2008 and ASTM E4.

Sample Compatibility & Compliance

The HY-0580YUVVNN accommodates standardized 100-mm sealing strip specimens mounted on glass or metal substrates using custom-designed clamping fixtures that minimize slippage and stress concentration. Its 120-mm effective test width and 800-mm vertical stroke support extended deformation analysis for viscoelastic recovery studies. The system meets mandatory requirements of multiple international standards—including GB/T 16491–2008 (electromechanical testing machines), GB/T 2611–2007 (general technical specifications), and harmonized methods such as ASTM D412 (rubber tensile properties), ISO 37 (vulcanized rubber), and JIS K6251. Optional software modules enable automatic compliance reporting against USP , FDA 21 CFR Part 11 audit trail requirements, and GLP/GMP documentation templates for regulated industries.

Software & Data Management

Bundled Hengyi TestMaster v4.2 software provides intuitive test configuration, real-time curve visualization (force vs. displacement, stress vs. strain), and automated report generation in PDF or Excel formats—including raw data export with timestamped metadata. All test parameters, operator ID, environmental notes, and calibration logs are embedded within each dataset. The software supports multi-user role-based access control, electronic signatures, and immutable audit trails compliant with 21 CFR Part 11 Annex 11. Customizable test sequences can be saved and recalled, while batch processing enables statistical analysis across up to 999 specimens per session. Data integrity safeguards include automatic backup to network drives, SHA-256 hash verification, and version-controlled firmware updates.

Applications

• Quantification of seal retention force in automotive door/window assemblies per OEM engineering specifications.
• Evaluation of aging effects on EPDM, TPE, and silicone sealants after thermal cycling, UV exposure, or humidity conditioning.
• Comparative assessment of adhesive bond strength between extruded rubber profiles and painted aluminum substrates.
• Mechanical screening of prototype gasket materials for HVAC, medical device enclosures, and cleanroom panel systems.
• Instructional use in university materials science laboratories for teaching fundamental concepts in Hookean behavior, yield point identification, and fracture energy calculation.
• Support for ISO 14001-compliant environmental product declarations by documenting mechanical durability over service life.

FAQ

What is the minimum measurable pull-out force for seal testing?
The system achieves sub-millinewton resolution when equipped with the 1 N load cell, supporting detection of initial debonding events in ultra-soft thermoplastic elastomers.
Can the machine perform cyclic loading or fatigue testing?
Yes—TestMaster v4.2 supports user-defined waveform profiles (sine, triangle, trapezoidal) with up to 100,000 cycles and real-time hysteresis loop analysis.
Is third-party calibration certification included with purchase?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China); optional UKAS-accredited calibration is available upon request.
How does the system ensure repeatability across operators?
Standardized fixture geometry, automated zeroing routines, and operator-independent test method libraries eliminate procedural variability.
Are custom grips or environmental chambers supported?
Hengyi offers ISO-standard wedge grips, pneumatic clamps, and integration-ready ports for temperature-controlled chambers (-40°C to +150°C) and humidity modules.
