Overview
The GOTECH GT-7036-A Paper Tube Crush Resistance Tester is a dedicated compression testing instrument engineered for precise evaluation of radial crush strength in cylindrical paper-based packaging components. It operates on the fundamental principle of axial compressive loading under controlled displacement rate, conforming to standardized mechanical testing methodologies used across global packaging R&D and quality control laboratories. The system applies a steadily increasing compressive force via a motor-driven upper platen onto a vertically oriented tubular specimen seated between parallel platens. Force transduction is achieved through a high-linearity load cell mounted in the upper crosshead, converting mechanical stress into calibrated analog voltage signals processed by an embedded digital controller. Real-time force data is displayed on a high-contrast LED screen with 0.1 N resolution, enabling immediate visual verification during test execution. Designed specifically for rigid hollow cylinders—including paper tubes, yarn bobbins, adhesive tape cores, and fiberboard cans—the GT-7036-A delivers repeatable, traceable results essential for compliance with ISO 12048 (Packaging—Complete, filled transport packages—Compression testing), ASTM D642 (Standard Test Method for Determining Compressive Resistance of Shipping Containers), and GB/T 2679.17 (Chinese national standard for paper tube crush resistance).
Key Features
- Motorized dual-column frame with precision-ground guide rods ensures vertical alignment stability and minimal lateral deflection during loading
- Adjustable compression speed range (1–50 mm/min) with programmable ramp profiles to match material deformation kinetics
- Integrated load cell with ±0.5% full-scale accuracy and thermal drift compensation for consistent measurement integrity across ambient temperature fluctuations
- Digital controller with real-time force readout (N or kgf units selectable), peak hold function, and automatic test termination upon preset load or displacement threshold
- Robust steel construction with powder-coated finish for long-term durability in industrial QC environments
- Quick-release platen mounting system allows rapid interchange of flat, curved, or custom-diameter platens to accommodate varying specimen geometries
Sample Compatibility & Compliance
The GT-7036-A accommodates specimens with outer diameters ranging from 25 mm to 150 mm and heights up to 300 mm, supporting standard paper tube configurations used in textile, adhesive, and food packaging sectors. Its design enables direct correlation with industry-accepted crush resistance specifications defined in TAPPI T 815 (Radial Compression Strength of Paper Tubes) and ISO 12048 Annex A (Test Conditions for Cylindrical Packages). All mechanical and electronic subsystems comply with IEC 61000-4 electromagnetic compatibility requirements and meet CE marking directives for machinery safety (2006/42/EC). Documentation includes factory calibration certificates traceable to NIM (National Institute of Metrology, China) standards, facilitating internal audit readiness for ISO 9001-certified facilities.
Software & Data Management
While the base GT-7036-A operates via standalone digital controller, optional RS-232 or USB interface modules enable bidirectional communication with external PCs running Windows-based data acquisition software. This configuration supports automated test sequencing, multi-sample batch logging, statistical analysis (mean, SD, CV%), and export to CSV or PDF formats. Audit trail functionality records operator ID, timestamp, test parameters, and raw force-displacement curves—supporting GLP-aligned documentation practices. For regulated environments, optional software add-ons provide 21 CFR Part 11-compliant user authentication, electronic signatures, and immutable data archiving.
Applications
- Quality assurance of paper cores supplied to tape, film, and foil converters
- Validation of recycled fiberboard tube performance under simulated warehouse stacking loads
- R&D benchmarking of bio-based composite tubes versus virgin kraft alternatives
- Supplier qualification testing per OEM packaging engineering specifications (e.g., automotive harness spools, medical device reels)
- Failure mode analysis of delamination or buckling onset in multi-ply laminated tubes
FAQ
What is the maximum crush load capacity of the GT-7036-A?
The standard configuration supports up to 5,000 N (approximately 500 kgf); higher-capacity variants (10 kN and 20 kN) are available upon request.
Can the machine perform tests at constant strain rate instead of constant speed?
No—the GT-7036-A operates exclusively in displacement-controlled mode; strain-rate control requires closed-loop servo-hydraulic systems not implemented in this electromechanical design.
Is third-party calibration certification included with purchase?
Yes—a NIM-traceable calibration certificate valid for 12 months is provided with each unit, along with calibration procedure documentation.
Does the tester meet FDA requirements for use in pharmaceutical packaging labs?
While the hardware itself is not FDA-regulated, its output data meets ALCOA+ principles when paired with compliant software; full 21 CFR Part 11 validation support is available as an upgrade package.
How often does the load cell require recalibration?
Annual recalibration is recommended; however, routine verification using certified deadweight standards should be performed before each daily shift in high-volume QC settings.
