YL-6609PC Series Computer-Controlled Compression Tester – Yuelian

Overview

The YL-6609PC Series Computer-Controlled Compression Tester is an electromechanical static compression testing system engineered for quantitative evaluation of compressive strength, stacking resistance, and structural integrity of corrugated fiberboard boxes, folding cartons, and rigid packaging containers. It operates on the principle of controlled uniaxial compression loading applied between parallel platens, measuring force-displacement-time response in accordance with standardized quasi-static mechanical testing protocols. Designed for quality assurance laboratories, packaging R&D centers, and production line validation environments, this instrument delivers repeatable, traceable, and audit-ready data essential for transport simulation compliance, shelf-life stability assessment, and regulatory documentation under ISO/IEC 17025-accredited testing practices.

Key Features

• Four scalable configurations (YL-6609PC-A to -D) accommodating test chamber volumes from 80 × 80 × 100 cm to 150 × 150 × 150 cm and load capacities up to 5000 kgf (49 kN), enabling flexible deployment across small-format retail packaging and industrial palletized unit loads.
• High-resolution load measurement with 1/250,000 full-scale resolution and ≤0.5% FS accuracy—certified per ASTM E4 and ISO 7500-1 Class 1 requirements—ensuring metrological traceability to national standards.
• Panasonic AC servo motor coupled with precision-ground arc-shaped ball-screw transmission provides smooth, low-backlash motion control, minimizing inertial artifacts during ramp-and-hold or creep testing sequences.
• Multi-unit load display and switching (kgf, N, kN, lbf, ton) with real-time digital readout and synchronized graphical plotting of force vs. displacement, force vs. time, and displacement vs. time curves.
• Programmable hold function supports sustained-load testing over durations ranging from 0.1 minute to >19 years (9999999 min), critical for evaluating long-term creep deformation and collapse behavior under static stack conditions.
• Comprehensive safety architecture includes dual-channel mechanical limit switches, programmable upper/lower platen position constraints, overload cutoff, and automatic return-to-start after test completion.

Sample Compatibility & Compliance

The YL-6609PC accommodates standard and custom-sized shipping containers—including single-wall, double-wall, and triple-wall corrugated board assemblies—as well as printed folding cartons, rigid set-up boxes, and molded pulp trays. Its open-frame design permits easy specimen placement and visual monitoring during compression. The system is fully compliant with internationally recognized packaging performance standards: TAPPI T804 (compression resistance of shipping containers), ISTA 1A/2A/3A (performance testing for packaged-products), JIS Z0212 (compressive strength of corrugated fiberboard boxes), and Chinese national standards GB/T 4857.3–2008 (static compression testing) and GB/T 4857.4–2008 (rotational drop and compression combined testing). All test methods are implemented with documented parameter settings and calibration records aligned with GLP and internal QA procedures.

Software & Data Management

The included Windows-based testing software provides intuitive workflow-driven operation—from test setup and method selection to real-time acquisition, post-test analysis, and report generation. Each test session logs timestamped metadata including operator ID, environmental temperature/humidity (when integrated with optional sensors), sample identification, test parameters, and raw channel data at user-defined sampling rates. Export formats include CSV, PDF, and XML for integration into LIMS or ERP systems. Audit trails comply with FDA 21 CFR Part 11 requirements when configured with electronic signatures and role-based access controls. Calibration certificates, maintenance logs, and version-controlled firmware updates are managed within the software’s administrative module.

Applications

• Determining maximum compressive load capacity of empty or product-filled cartons prior to distribution.
• Validating stack height limits for warehouse racking and ocean container stowage based on empirical collapse thresholds.
• Comparing material substitutions (e.g., flute profile changes, recycled content ratios) through controlled inter-lot strength benchmarking.
• Supporting ISTA-certified package development by replicating static compression profiles encountered during multi-tier pallet stacking.
• Generating input data for finite element modeling (FEM) of box deformation mechanics and corner crush resistance prediction.
• Facilitating root-cause analysis of field failures by correlating lab-measured compression curves with in-transit damage reports.

FAQ

What standards does the YL-6609PC support out-of-the-box?

It natively implements test sequences and pass/fail criteria for TAPPI T804, ISTA 1A/2A/3A, JIS Z0212, and GB/T 4857.3–4. Custom method templates can be created for proprietary or emerging standards.
Can the system perform cyclic or dynamic compression tests?

No—the YL-6609PC is designed exclusively for static and quasi-static compression per ISO 17987 and ASTM D642. For dynamic or impact testing, complementary equipment such as drop testers or vibration shakers is recommended.
Is third-party calibration certification available?

Yes—factory calibration is performed using NIST-traceable deadweight standards. Optional UKAS- or CNAS-accredited calibration certificates with uncertainty budgets are available upon request.
How is data integrity ensured during extended hold tests?

The controller maintains continuous data logging at ≥10 Hz even during multi-day holds, with non-volatile memory backup and checksum verification to prevent corruption or loss.
Does the software support multi-user environments with permission tiers?

Yes—administrator, technician, and viewer roles can be assigned with granular permissions for method editing, test execution, data export, and system configuration.
