YueLian PW-CHL150-40A-FR6 Low-Temperature Fold Endurance Tester

Overview

The YueLian PW-CHL150-40A-FR6 Low-Temperature Fold Endurance Tester is an engineered solution for evaluating the mechanical fatigue resistance of flexible packaging materials, leather, synthetic leather, textiles, and coated papers under controlled thermal stress. Unlike ambient-condition fold testers, this instrument integrates a precision environmental chamber with a synchronized multi-station folding mechanism—enabling standardized durability assessment across temperature extremes defined in ISO 32100, ISO 5402-1, GB/T 3903.41–2019, ASTM D2176, BS 3144, JIS K6545, and SATRA TM55. Its core principle relies on repeated angular flexing (22.5°) at programmable frequencies (0–100 ±3 cycles per minute), while maintaining stable chamber conditions from −40 °C to +150 °C. This dual-domain capability—mechanical cycling + thermal conditioning—ensures data relevance for real-world applications such as cold-chain packaging integrity, winter-grade automotive interiors, or outdoor technical fabrics.

Key Features

• Integrated dual-function architecture: independent high-fidelity temperature chamber (−40 °C to +150 °C) co-located with six parallel folding stations—eliminating sequential testing delays and inter-test thermal drift.
• Precision climate control system featuring a Copeland (TaiKang) hermetic compressor, SWEP high-efficiency brazed plate heat exchanger, and 100 mm thick rigid polyurethane insulation—achieving ≤±0.5 °C stability and ≤2 °C uniformity per IEC 60068-3-5.
• Robust mechanical drive train: brushless DC motor with optical encoder feedback, coupled to hardened stainless steel camshafts and low-backlash timing belts—ensuring long-term repeatability of folding angle (22.5° ±0.3°) and speed (0–100 ±3 cpm).
• Corrosion-resistant internal chamber: fully lined with #304 stainless steel; radius-rounded corners and sloped floor design facilitate residue-free cleaning—critical for GLP-compliant validation protocols.
• Human-centered operator interface: Weilun TH7010 touchscreen controller with programmable ramp-soak profiles, real-time graphing, USB data export, and password-protected parameter locking—supporting audit-ready operation per FDA 21 CFR Part 11 requirements.
• Enhanced safety and serviceability: triple-layer vacuum-insulated viewing window (320 × 420 × 40 mm), LED interior lighting, front-accessible condenser and filter modules, and SUS #304 heavy-duty hinges rated for >100,000 cycles.

Sample Compatibility & Compliance

The PW-CHL150-40A-FR6 accommodates standardized specimens measuring 70 × 45 mm—compatible with die-cut templates per ISO 32100 Annex A and GB/T 3903.41 Clause 6.2. It supports single-layer and laminated substrates including PET/AL/PE pouches, PU-coated nylon, chrome-tanned leather, Tyvek® medical packaging, and fiber-reinforced composites. All mechanical and thermal performance metrics are traceable to NIST-calibrated reference standards. The system meets structural and operational requirements of ISO/IEC 17025 for test equipment used in accredited laboratories, and its firmware logging architecture satisfies electronic record retention mandates under EU Annex 11 and USP .

Software & Data Management

Data acquisition is managed via embedded TH7010 firmware with timestamped cycle counting, temperature logging (sampled every 2 seconds), and automatic endpoint detection (e.g., crack initiation, complete rupture). Raw datasets export in CSV format for post-processing in MATLAB, JMP, or LIMS platforms. Optional Ethernet connectivity enables remote monitoring and integration into centralized lab infrastructure. Audit trails—including user ID, parameter changes, calibration events, and test start/stop timestamps—are retained for ≥12 months and support full 21 CFR Part 11 compliance when paired with organizational electronic signature policies.

Applications

• Accelerated aging studies of pharmaceutical blister packaging under sub-zero storage conditions.
• Validation of fold endurance for EV battery module thermal interface materials subjected to −30 °C startup cycles.
• Quality conformance testing of footwear uppers per SATRA TM55 and ISO 5402-1.
• R&D evaluation of biodegradable films (e.g., PLA-based laminates) under combined thermal-mechanical stress.
• Supplier qualification audits requiring documented adherence to GB/T 20991–2007 for flexible food packaging.

FAQ

What international standards does this tester directly support?
It is configured and validated for ISO 32100, ISO 5402-1, GB/T 3903.41–2019, ASTM D2176, BS 3144, JIS K6545, and SATRA TM55—with mechanical and thermal parameters aligned to each standard’s procedural tolerances.
Can the folding speed be calibrated independently per station?
No—six stations operate synchronously at the same programmed frequency to ensure inter-channel comparability; however, individual station load cells (optional add-on) allow differential force monitoring.
Is external calibration certification included with delivery?
Factory calibration certificates for temperature uniformity and folding angle accuracy are provided; third-party ISO/IEC 17025 calibration services are available upon request.
What maintenance intervals are recommended for sustained accuracy?
Compressor oil and refrigerant levels should be verified annually; camshaft lubrication and belt tension inspection are required every 500 operational hours; temperature sensor verification is advised quarterly using NIST-traceable dry-block calibrators.
Does the system support automated pass/fail reporting?
Yes—the TH7010 controller allows user-defined failure thresholds (e.g., “terminate test after 50,000 cycles or first visible crack”) and generates PDF summary reports with embedded test graphs and metadata.
