Labthink C611B Compression Tester for Corrugated Boxes and Hollow Containers

Overview

The Labthink C611B Compression Tester is a precision-engineered mechanical testing system designed for quantitative evaluation of compressive strength, deformation behavior, and stacking performance of corrugated fiberboard containers, honeycomb packaging, and hollow rigid containers—including plastic drums, paper barrels, fiber cans, and intermediate bulk containers (IBCs). It operates on the principle of controlled uniaxial compression using dual high-precision ball-screw actuators driven by a brushless servo motor, ensuring stable force application and repeatable displacement control across its full speed range (0–200 mm/min). The instrument complies with internationally recognized test standards including ASTM D642 (compression resistance of shipping containers), ASTM D4169 (performance testing of distribution systems), TAPPI T804 (compressive strength of corrugated fiberboard), ISO 12048 (packaging—compression testing of transport packages), JIS Z0212 (testing methods for corrugated fiberboard boxes), GB/T 16491 (universal testing machines), GB/T 4857.4 (compression testing of packages), and QB/T 1048–2004 (paper drum specifications). Its architecture supports both static load-hold and dynamic ramp-to-failure protocols, enabling rigorous assessment of structural integrity under simulated logistics conditions.

Key Features

• Integrated embedded computing platform running a Windows-based GUI—no external PC required; full instrument control, real-time data visualization, and report generation are handled onboard
• Dual high-accuracy ball-screw transmission system with servo-motor drive ensures precise speed regulation (±2% accuracy) and low mechanical hysteresis
• Triple 9 kN load cells configured in parallel provide redundancy, extended dynamic range, and improved signal stability; force resolution of 1 N and deformation resolution of 0.1 mm
• Programmable test modes: Crush Test (peak load at failure), Stack Test A (deformation under constant load over time), and Stack Test B (load maintenance at target deformation)
• Comprehensive safety architecture: overload protection, end-of-stroke limit switches, automatic fault detection, and audible/visual alarm signaling
• Multi-interface connectivity: USB 2.0 port for peripheral devices (keyboard, mouse, printer) and RJ45 Ethernet port for LAN integration and remote data export
• Optional DataShield™ data management module enables secure audit trails, role-based access control, electronic signatures, and seamless integration with LIMS or ERP systems

Sample Compatibility & Compliance

The C611B accommodates a broad spectrum of packaging geometries and materials. Standard platen dimensions (600 mm × 600 mm) and adjustable vertical clearance (up to 600 mm) allow testing of standard RSC, HSC, and telescoping cartons, as well as oversized industrial containers. Hollow cylindrical and rectangular vessels—including fiber-reinforced paper drums, HDPE/PP composite drums, and laminated fiber cans—are evaluated without fixture modification. All test routines adhere to GLP-aligned data integrity requirements. When equipped with optional GMP-compliant software configuration, the system satisfies FDA 21 CFR Part 11 criteria for electronic records and signatures, including time-stamped audit logs, user authentication, and immutable data archiving—making it suitable for pharmaceutical, medical device, and regulated food packaging validation.

Software & Data Management

The onboard software provides intuitive navigation via keyboard and optical mouse, supporting multi-language UI (English default). Real-time graphs display force vs. time, force vs. displacement, and displacement vs. time, with configurable sampling rates up to 100 Hz. Each test record includes metadata (operator ID, sample ID, environmental conditions, calibration status), raw waveform data, and calculated metrics (peak crush load, yield point, creep deformation at specified intervals). Reports are exportable in PDF, CSV, and XML formats. With DataShield™ enabled, all actions—including method edits, result approvals, and calibration events—are logged with digital signatures and tamper-proof timestamps. System backups can be scheduled automatically to network drives or external USB storage, ensuring continuous compliance with ISO/IEC 17025 and ICH Q5C traceability expectations.

Applications

• Corrugated box qualification per ASTM D642: determination of maximum compressive load prior to collapse, used to predict palletized stack height limits
• Dynamic stack simulation per ASTM D4169 Cycle 13: sequential application of increasing loads to replicate warehouse storage scenarios
• Honeycomb panel structural analysis: evaluation of buckling resistance and energy absorption characteristics under axial loading
• Regulatory submission support for pharmaceutical secondary packaging: verification of container integrity during long-term ambient or accelerated aging studies
• Supplier quality assurance: incoming inspection of paper drums per QB/T 1048–2004, including crush strength and dimensional stability after moisture conditioning
• Material development R&D: comparative testing of novel fiber blends, recycled content formulations, and bio-based barrier coatings under standardized compression profiles

FAQ

What standards does the C611B comply with for international regulatory submissions?

The instrument meets ASTM, ISO, TAPPI, JIS, and GB series standards. With optional GMP software and DataShield™, it fulfills FDA 21 CFR Part 11 and EU Annex 11 requirements for electronic data integrity.
Can the C611B perform creep tests beyond 24 hours?

Yes—its embedded controller supports uninterrupted test durations up to 168 hours (7 days) with automatic data logging at user-defined intervals.
Is calibration traceable to national metrology institutes?

All load cells are factory-calibrated against NIST-traceable reference standards; certificate of calibration is provided with each unit and includes uncertainty budgets per ISO/IEC 17025.
Does the system support custom test method scripting?

Advanced users may define multi-step load/deformation profiles using the built-in method editor, including conditional branching based on real-time sensor feedback.
What maintenance is required to sustain measurement accuracy?

Annual recalibration is recommended; routine checks include platen parallelism verification, ball-screw lubrication, and encoder alignment—procedures documented in the service manual and supported remotely by Labthink Field Engineers.
