Labthink C611B Compression Tester for Corrugated Boxes and Hollow Containers

Overview

The Labthink C611B Compression Tester is an integrated, high-precision mechanical testing system engineered for quantitative evaluation of compressive strength, deformation behavior, and stacking performance of corrugated fiberboard containers—including standard and honeycomb cardboard boxes—as well as hollow rigid packaging such as plastic drums, paper cans, composite pails, and intermediate bulk containers (IBCs). Operating on the principle of controlled uniaxial compression under constant-rate or constant-load conditions, the instrument applies calibrated axial force via dual precision ball-screw actuators driven by a servo motor. Real-time acquisition of load and displacement data enables compliance with standardized static and dynamic compression protocols defined in ASTM D642 (determination of compressive resistance), ASTM D4169 (performance testing of shipping containers), ISO 12048 (compression testing of corrugated fiberboard boxes), TAPPI T804, JIS Z0212, GB/T 4857.4, and QB/T 1048–2004. Its architecture supports both destructive crush testing and non-destructive creep/stacking simulations—critical for validating packaging integrity across supply chain logistics, warehouse storage, and distribution environments.

Key Features

• Compact all-in-one design with embedded industrial computer platform—no external PC required; Windows-style GUI enables intuitive operation via keyboard and optical mouse.
• Dual high-accuracy ball-screw transmission system coupled with a brushless servo motor ensures smooth, repeatable motion control and programmable test speed from 0 to 200 mm/min (integer-step adjustment).
• Triple 9 kN load cells (redundant configuration) deliver robust force measurement across wide dynamic range: ±1% accuracy (10–100% full scale), ±0.1% FS at low-force regime (0–10% FS); 1 N force resolution and 0.1 mm displacement resolution.
• Comprehensive safety architecture includes electronic overload protection, mechanical end-stop limit switches, real-time fault diagnostics, and audible/visual alarm activation.
• Standard USB 2.0 and Ethernet interfaces support direct data export, remote monitoring, and integration into enterprise laboratory information management systems (LIMS).
• Optional DataShield™ software module provides audit-trail-enabled data governance, role-based access control, electronic signatures, and 21 CFR Part 11–compliant record retention—certified for GMP-regulated pharmaceutical packaging validation.

Sample Compatibility & Compliance

The C611B accommodates specimens up to 600 mm in height and 600 × 600 mm in footprint, enabling evaluation of full-size shipping cartons and large-format IBCs. It supports three standardized test modes: (1) Crush Test per ASTM D642, measuring peak compressive load at failure; (2) Stacking Test A (constant-rate loading), quantifying deformation under progressive load; and (3) Stacking Test B (constant-load holding), assessing time-dependent creep strain under sustained stress—aligned with ISO 12048 Annex B and GB/T 4857.4 Clause 6. All test routines are preconfigured to enforce strict adherence to method-defined dwell times, loading rates, and environmental conditioning prerequisites. The system meets mechanical safety requirements per IEC 61000-6-2/6-4 and carries CE marking for EMC and low-voltage directive compliance.

Software & Data Management

Built-in Labthink TestSuite™ software provides real-time graphical display of force–displacement curves, automatic calculation of key metrics—including maximum compressive load, yield point, elastic modulus, and permanent deformation—and generation of PDF/CSV reports with embedded metadata (operator ID, timestamp, calibration status, environmental conditions). Data encryption, write-once-read-many (WORM) archiving, and configurable backup intervals ensure ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) are maintained throughout the data lifecycle. Optional GMP-compliant computer system qualification packages include IQ/OQ documentation, user requirement specification (URS) alignment, and traceable calibration certificates issued by CNAS-accredited laboratories.

Applications

• Corrugated box qualification: crush resistance verification for e-commerce fulfillment centers and cold-chain logistics providers.
• Stacking simulation: prediction of palletized load stability during multi-tier warehouse storage (ASTM D4169 Cycle 10–12).
• Hollow container validation: structural integrity assessment of HDPE drums and fiber-reinforced composite pails used in chemical transport.
• Regulatory submission support: generation of GLP-compliant test reports for FDA 21 CFR Part 11, EU Annex 11, and PIC/S GMP Annex 15 submissions.
• Material development R&D: comparative analysis of flute geometry, adhesive formulation, and moisture barrier coatings on compression performance.
