Hengyi HY-0580QRT Single-Arm Electronic Tensile Testing Machine for Cosmetic Brush Bristle Pull-Out Force Measurement

Overview

The Hengyi HY-0580QRT is a precision-engineered single-arm electronic tensile testing machine specifically configured for quantitative mechanical evaluation of cosmetic brush bristle adhesion strength — commonly referred to as “bristle pull-out force.” It operates on the fundamental principle of uniaxial static load application under controlled displacement or load rate, compliant with standardized test methodologies defined in ISO 1798, ASTM D3043, and GB/T 1040.1–2018 for tensile property assessment of low-force, high-resolution specimens. Designed for laboratory-grade repeatability and regulatory traceability, the system delivers calibrated force measurement across a wide dynamic range (0.001–100% FS), enabling reliable quantification of interfacial bonding integrity between synthetic or natural bristles and ferrule substrates (e.g., aluminum, plastic, or wood). Its rigid C-frame architecture, coupled with a high-stiffness load cell and closed-loop servo control, ensures minimal deflection-induced error and high reproducibility in sub-newton to kilonewton-scale measurements.

Key Features

• Single-column, space-efficient design (470 × 400 × 1510 mm) optimized for benchtop integration in QC labs and R&D environments
• High-resolution load measurement system with ±0.5% accuracy over full scale; no internal range switching required
• Adjustable crosshead speed from 0.001 to 500 mm/min, programmable in real time with ±0.5% speed fidelity
• Displacement resolution of 0.001 mm, supported by linear encoder feedback for precise stroke tracking
• Dual-speed motorized crosshead actuation (fast jog + fine positioning) with electronic limit protection and emergency stop
• Auto-return functionality post-test, including programmable return-to-start and conditional termination (load-, displacement-, or time-based)
• Overload protection at 110% of maximum rated load (5 kN), plus integrated diagnostic monitoring for drive, sensor, and power subsystems
• Compliance-ready firmware architecture supporting audit trails, user access levels, and data integrity protocols aligned with GLP and ISO/IEC 17025 requirements

Sample Compatibility & Compliance

The HY-0580QRT accommodates standard and custom fixtures for clamping individual brush heads, multi-bristle arrays, or segmented bristle bundles (max. specimen width: 120 mm). Its modular grip interface supports pneumatic, wedge, and vise-type holders compatible with soft polymers (nylon, polyester), natural fibers (kolinsky, squirrel), and composite filaments. All mechanical tests conform to internationally recognized standards including ISO 16840-2 (brush performance), ASTM F2924 (cosmetic applicator durability), and relevant clauses of USP for applicator functional testing. The system’s calibration certificate is traceable to NIM (National Institute of Metrology, China) and supports third-party verification per ISO/IEC 17025:2017.

Software & Data Management

Equipped with Hengyi’s proprietary WinTest Pro software (v4.2+), the HY-0580QRT provides real-time force-displacement curve visualization, automated peak detection, and customizable report generation (PDF/Excel). The software enforces ALCOA+ principles: attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available. Audit trail logging records all operator actions, parameter changes, and calibration events. Data export supports CSV, XML, and .tdms formats for integration into LIMS or statistical process control (SPC) platforms. Optional 21 CFR Part 11 compliance package includes electronic signatures, role-based permissions, and immutable data archiving.

Applications

• Quantitative evaluation of bristle retention force in cosmetic brushes (face, eye, lip) during product development and supplier qualification
• Comparative analysis of adhesive bond strength across different ferrule materials, curing processes, and bristle insertion methods
• Accelerated aging studies assessing mechanical degradation of brush assemblies after thermal/humidity cycling or solvent exposure
• QC release testing per internal SOPs aligned with ISO 22716 (Cosmetics — Good Manufacturing Practices)
• Material screening for alternative bristle chemistries (e.g., bio-based PA610, PBT blends) against baseline nylon performance
• Supporting regulatory submissions requiring mechanical stability evidence for Class I/II cosmetic devices

FAQ

What is the minimum measurable pull-out force for bristle testing?
The system achieves stable resolution down to 0.005 N (equivalent to ~0.5 gf) at full 5 kN capacity, enabled by 500,000-count A/D conversion and noise-immune signal conditioning.
Can the HY-0580QRT perform cyclic loading or fatigue tests?
Yes — WinTest Pro supports programmable load/displacement waveforms (sinusoidal, trapezoidal, block) with up to 100,000-cycle capability and real-time hysteresis analysis.
Is third-party calibration documentation included?
Each unit ships with a factory calibration certificate traceable to national standards; optional ISO/IEC 17025-accredited calibration is available upon request.
Does the system support ASTM D3330 peel testing for adhesive-backed brush components?
With appropriate 180° peel fixture and alignment jig, the HY-0580QRT meets ASTM D3330 requirements for low-speed peel force measurement (1–300 mm/min).
What maintenance intervals are recommended for long-term accuracy?
Load cell verification every 6 months; annual mechanical inspection of lead screws, bearings, and encoder coupling; firmware updates provided free of charge for registered users.
