Yuelian PW-6600 Automatic Compression Tester for Corrugated Board and Paper Tube Strength

Overview

The Yuelian PW-6600 Automatic Compression Tester is a precision-engineered mechanical testing system designed specifically for the packaging industry to quantify compressive resistance properties of paper, board, and cylindrical paper tubes. It operates on the principle of controlled uniaxial compression using dual-platen loading geometry, delivering repeatable force-displacement profiles under standardized displacement rates. The instrument is calibrated to meet the fundamental mechanical test requirements defined in major national standards—including GB/T 2679.8 (Ring Crush Test, RCT), GB/T 6546 (Edge Crush Test, ECT), GB/T 6548 (Ply Adhesion Test, PAT), GB/T 2679.6 (Flat Crush Test, FCT), and CMT (Corrugated Medium Test) for small-diameter paper cores (<60 mm). Its rigid stainless-steel architecture, coupled with high-resolution load cell feedback and synchronized motion control, ensures traceable, GLP-compliant data acquisition across production QC labs, R&D facilities, and third-party certification bodies.

Key Features

• Full stainless-steel structural frame with precisely aligned fixture mounting points—ensuring long-term dimensional stability and eliminating mechanical hysteresis.
• 7-inch high-contrast TFT LCD touchscreen interface with real-time force vs. displacement curve visualization—enabling immediate assessment of deformation onset, peak load, and collapse behavior.
• Dual-speed electromechanical drive system: constant 12 mm/min test and return velocity—aligned with ISO/GB standard displacement rate requirements for reproducible inter-laboratory comparisons.
• Onboard statistical engine calculating arithmetic mean, minimum/maximum values, and standard deviation—automatically converting raw load data into standardized strength units (kN/m for ECT/RCT, N for PAT/CMT, kPa for FCT).
• Role-based parameter access control—restricting calibration, test method editing, and system configuration to authorized personnel only.
• Ethernet interface supporting TCP/IP communication with Windows-based PC software—enabling remote operation, batch test scheduling, audit-trail logging, and electronic signature support per FDA 21 CFR Part 11 guidelines.
• Integrated thermal printer and internal memory (50 test records)—providing immediate hardcopy output and local data redundancy without external dependency.

Sample Compatibility & Compliance

The PW-6600 accommodates a wide range of standardized specimens used in corrugated packaging quality assurance: 15.2 mm × 15.2 mm RCT strips (0.15–1.00 mm thickness), 25 mm ECT samples, 25 mm × 25 mm PAT specimens, 100 mm × 100 mm FCT panels, and cylindrical paper cores up to 60 mm in diameter. All test geometries conform to platen size specifications (124 mm upper, 127 mm lower) and parallelism tolerances required by GB/T standards. The instrument’s mechanical design satisfies ISO 7500-1 Class 1 accuracy classification for force measurement systems. Calibration certificates are traceable to national metrology institutes, and routine verification protocols align with ISO/IEC 17025 requirements for accredited testing laboratories.

Software & Data Management

The companion Windows application provides full instrument control, method library management, and compliant data handling. Users define test templates—including specimen type, expected failure mode, pass/fail thresholds, and reporting format—prior to execution. All test sessions generate timestamped, user-annotated datasets with embedded metadata (operator ID, environmental conditions, calibration status). Reports comply with A4 layout standards and include graphical curves, tabulated statistics, and digital signatures. Audit trails record every action—from test initiation to report export—with immutable timestamps. Data export supports CSV, PDF, and XML formats for integration into LIMS or ERP systems. Software updates are delivered via secure HTTPS channels with version-controlled release notes.

Applications

This tester serves as a core QA/QC tool across the paper-to-packaging value chain: pulp and paper mills use it for incoming raw material qualification and process optimization; corrugated board manufacturers rely on it for ECT/RCT correlation modeling and linerboard specification validation; box plants apply it for finished board certification and batch release; end-user converters perform incoming inspection and shelf-life simulation studies; and regulatory agencies deploy it during surveillance testing and standard conformance audits. Its ability to deliver consistent, standards-aligned results makes it suitable for ISO 9001 internal audits, customer-facing documentation, and technical submissions to certification bodies such as SGS, Intertek, or CNAS.

FAQ

Does the PW-6600 support ASTM or ISO standards in addition to GB/T?
Yes—the mechanical design and control algorithm are compatible with ASTM D6322 (RCT), ASTM D642 (compression), ISO 3037 (ECT), and ISO 12192 (FCT); however, method configuration must be manually aligned with respective procedural clauses.
Can test data be exported directly to Excel or LIMS?
Yes—CSV and XML exports include all raw and calculated parameters, with column headers mapped to common LIMS field definitions.
Is firmware upgrade capability available remotely?
Firmware updates require local USB installation; however, software updates and method libraries can be deployed over Ethernet.
What maintenance intervals are recommended for long-term accuracy?
Annual verification against certified reference loads is advised; daily zero-check and monthly platen parallelism verification are included in the operator manual.
Is the instrument suitable for GLP-regulated environments?
Yes—when configured with enabled audit trail, electronic signatures, and role-based access, it meets foundational GLP data integrity requirements per OECD Principles of Good Laboratory Practice.
