Yuelian PW-SS64T Constant-Temperature Holding Force Tester

Overview

The Yuelian PW-SS64T Constant-Temperature Holding Force Tester is an engineered solution for quantitative assessment of static adhesive performance under ambient thermal conditions. Designed in accordance with core principles of mechanical creep and load-sustained deformation analysis, this instrument applies a precisely defined axial tensile force—via calibrated dead-weight loading—to adhesive specimens mounted vertically on standardized test plates. The system continuously monitors the time-to-failure (i.e., specimen detachment or measurable displacement beyond threshold) under constant load, delivering objective, reproducible data critical for quality control, formulation development, and regulatory documentation in pressure-sensitive adhesive (PSA) manufacturing. Unlike dynamic peel or shear testers, the PW-SS64T emphasizes long-duration, low-stress retention behavior—directly correlating to real-world application scenarios such as label adhesion on packaging, protective film anchoring on display surfaces, or medical tape integrity during extended wear.

Key Features

• High-throughput parallel testing architecture: 64 independent test stations distributed across four vertically stacked layers, enabling statistically robust batch evaluation without sequential delay.
• Integrated industrial-grade touchscreen HMI with reverse-countdown timer, real-time status visualization (color-coded green/amber/red indicators), and multi-page data navigation for simultaneous monitoring of all stations.
• Rigid structural platform constructed from anodized aluminum extrusions, powder-coated sheet metal, and stainless steel components—optimized for dimensional stability, corrosion resistance, and long-term load-bearing integrity.
• Passive vibration isolation system comprising closed-cell polymeric foam padding and perimeter stainless steel guardrails, minimizing environmental micro-motion interference during extended hold tests (up to 72+ hours).
• Modular weight-loading design: standard 1 kg stainless steel砝码 supplied per station; optional accessory kits support 0.5 kg, 2 kg, and 5 kg loads to accommodate diverse adhesive strength classes per ASTM D3654 and GB/T 4851 standards.
• Low-power operation (200 W nominal) with thermal management ensuring stable ambient-temperature testing conditions—no active climate control required, reducing energy dependency and operational complexity.

Sample Compatibility & Compliance

The PW-SS64T accommodates a broad range of planar adhesive substrates including solvent-based and water-based acrylic PSAs, rubber-based tapes, silicone release liners, PET/PE protective films, and double-sided mounting foams. Specimen mounting follows standardized protocols: 25 mm × 25 mm or 25 mm × 100 mm cut samples affixed to conditioned stainless steel test plates using controlled roller pressure (2 kg, 10 rpm, single pass). The system supports compliance with internationally recognized test methods—including ASTM D3654 (Standard Test Method for Holding Power of Pressure-Sensitive Tapes), ISO 4587 (Adhesives — Determination of Tensile Shear Adhesion Strength), and GB/T 4851–2014 (Chinese national standard for holding power of adhesives). Its mechanical design and documentation trail are compatible with GLP-aligned laboratory environments requiring traceable calibration records and operator audit logs.

Software & Data Management

While the PW-SS64T operates via embedded firmware without external PC dependency, its touchscreen interface enables timestamped event logging—including start time, detachment time (or displacement trigger), station ID, and operator code. All data are exportable via USB flash drive in CSV format for downstream analysis in Excel, Minitab, or LIMS platforms. Optional firmware upgrade paths support enhanced features such as automated pass/fail thresholding (e.g., displacement > 1.0 mm within 1 hr), scheduled test initiation, and integration-ready RS-232/RS-485 serial output for centralized lab automation systems. Audit trails meet foundational requirements for FDA 21 CFR Part 11 readiness when paired with institutional electronic signature policies.

Applications

• Quality assurance screening of incoming raw materials (e.g., acrylic monomer batches, tackifier resins) prior to coating line integration.
• Formulation optimization trials evaluating the impact of crosslinker concentration, plasticizer addition, or polymer molecular weight distribution on long-term creep resistance.
• Comparative benchmarking against competitor products under identical load and environmental conditions.
• Stability studies assessing shelf-life-related degradation of adhesive cohesion under accelerated aging protocols (when used post-aging chamber exposure).
• Technical support documentation for customer-facing specifications, particularly in automotive trim bonding, electronics assembly masking, and pharmaceutical transdermal patch validation.

FAQ

What adhesive sample dimensions are supported?
Standard test specimens are 25 mm × 25 mm or 25 mm × 100 mm; custom jigs can be fabricated for non-standard geometries upon request.
Is temperature control integrated into the system?
No—the PW-SS64T is designed for ambient-temperature testing only (18–25°C, 40–60% RH recommended); environmental chambers must be used separately for elevated- or low-temperature variants.
Can test data be exported in real time to a networked database?
Direct Ethernet or Wi-Fi connectivity is not included; however, USB-exported CSV files may be ingested via middleware or scripted ingestion tools into enterprise databases.
What maintenance is required for long-term reliability?
Biannual inspection of load plate flatness, verification of weight calibration traceability (NIST-traceable certified masses recommended annually), and cleaning of touchscreen and guide rails with isopropyl alcohol.
Does the system comply with ISO/IEC 17025 requirements?
The hardware and documented procedures support ISO/IEC 17025 implementation; full accreditation requires site-specific validation, uncertainty budgeting, and participation in interlaboratory comparison programs.
