Paper Box Compression Tester – OKE Series

Overview

The OKE Series Paper Box Compression Tester is a dedicated mechanical testing instrument engineered for the quantitative evaluation of compressive load-bearing capacity in corrugated fiberboard containers, solid fiber boxes, and other rigid packaging structures. It operates on the principle of controlled uniaxial compression—applying a steadily increasing vertical force until specimen failure (crush point) or until a user-defined hold time and load level is reached. The system conforms to standardized test methodologies defined by ASTM D642 (“Standard Test Method for Determining Compressive Resistance of Shipping Containers”), ISO 12048 (“Packaging—Complete, filled transport packages—Compression and stacking tests”), and TAPPI T804 (“Compressive Strength of Corrugated Fiberboard Boxes”). Designed for quality assurance laboratories, packaging R&D departments, and third-party certification facilities, this tester delivers repeatable, traceable, and auditable results essential for compliance-driven industries including logistics, e-commerce fulfillment, pharmaceutical secondary packaging, and food & beverage distribution.

Key Features

• High-stability vertical actuation system driven by a Taiwan-sourced AC frequency-controlled motor, enabling precise speed regulation (1–20 mm/min adjustable) and consistent force ramping profiles.
• Preloaded precision-ground ball screw assembly ensures minimal backlash, low friction, and long-term positional repeatability over thousands of test cycles.
• U.S.-manufactured explosion-proof load cell with ±0.5% full-scale accuracy and integrated temperature compensation—certified to NIST-traceable calibration standards.
• Dedicated microprocessor-based controller featuring real-time load/displacement monitoring, programmable test modes (peak load, constant-rate compression, creep-hold, and stack simulation), and automatic crush detection with sub-millisecond response latency.
• Integrated thermal printer provides immediate hard-copy output of test parameters, peak load value (in kgf, lbf, or N), deformation curve summary, and timestamped test ID—no external PC required.
• Robust steel frame with reinforced load platens (300 × 300 mm standard, customizable up to 600 × 600 mm) accommodates standard RSC, HSC, and die-cut shipping containers per ISTA and ASTM dimensional guidelines.

Sample Compatibility & Compliance

The OKE Series accommodates specimens ranging from small retail cartons (≥100 mm height) to full-size palletized master cases (up to 1,200 mm height with optional extension column). Specimen alignment is facilitated by dual-axis leveling feet and adjustable lower platen guides. All test protocols are aligned with internationally recognized packaging performance standards: ASTM D642 (static compression), ASTM D4577 (stacking simulation), ISO 12048 (compressive strength under sustained load), and TAPPI T804 (edge crush correlation). Instrument validation documentation supports GLP-compliant environments; raw data logs include operator ID, environmental temperature/humidity tags (when interfaced with optional sensors), and electronic signature fields for audit readiness per FDA 21 CFR Part 11 when paired with optional software modules.

Software & Data Management

While the base unit operates autonomously via its embedded controller, an optional Windows-compatible PC software package enables advanced data management: batch test sequencing, statistical process control (SPC) charting (X-bar/R, Cp/Cpk), PDF report generation with company branding, and CSV export compatible with LIMS and MES platforms. Software logs include full audit trails—recording parameter changes, calibration events, user logins, and test interruptions—with immutable timestamps. Data encryption and role-based access control align with ISO/IEC 27001 information security frameworks.

Applications

• Validation of box design integrity prior to mass production launch.
• Comparative evaluation of flute configurations (e.g., B-flute vs. BC-double-wall) and linerboard grades under identical compression profiles.
• Stack load simulation for warehouse storage planning and pallet configuration optimization.
• Supplier qualification testing per ISO 9001 Clause 8.4.2 (control of externally provided processes).
• Root cause analysis of field failures involving crushed shipments or collapsed pallets.
• Supporting ISTA 3A, 3E, and 3H test protocols for e-commerce packaging certification.

FAQ

What standards does this tester support out-of-the-box?
ASTM D642, ISO 12048, and TAPPI T804 test methods are preconfigured in the controller firmware.
Can the system perform long-duration creep tests (e.g., 24–72 hours)?
Yes—the controller supports programmable hold phases at user-defined loads, with automatic data sampling intervals down to 1-second resolution.
Is calibration certificate included with shipment?
Each unit ships with a factory-issued calibration report traceable to NIST standards, valid for 12 months under normal operating conditions.
What maintenance is required for long-term accuracy?
Annual verification of load cell linearity and ball screw lubrication is recommended; no consumables or proprietary tools are required.
Does the thermal printer support label formats for internal QA tracking?
Yes—customizable print templates allow inclusion of lot numbers, operator codes, and QC pass/fail flags directly on test reports.
