Bending Stiffness Tester


Introduction: Based on the two-point loading principle, WTD-01 Bending Resistance Tester is used for determining the bending resistance of paper and board. It applies to the measurement of the bending resistance within the range 20 mN to10000 mN. It is not applicable to corrugated board but can be applicable to the components of such board. Terms: bending force: force required to bend a rectangular test piece clamped at one end. bending resistance: mean of all valid readings of the measured bending force calculated. Bending resistance is expressed in newtons or millinewtons. bending length: constant radial distance between the clamp and the position on the test piece at which the force is applied bending angle: angle through which the clamp rotates while moving from its initial position to the position at which the bending resistance is measured free length: total length of the test piece that projects from the clamp Why do you need a bending stiffness tester? Paper and board bending stiffness is a measure of the material's resistance to bending or deformation. Bending stiffness is crucial in applications where the material needs to maintain its shape or resist deformation, such as in packaging, printing, and various paper-based products. High bending stiffness can contribute to better performance in terms of rigidity and stability. Technical Features: Multi-angle Measurement: Allows for simultaneous setup of up to 3 test angles. Commonly used test angles include 7.5°, 15°, and 30°. Bending Time: Offers the flexibility to choose different bending times based on the material's elasticity. User Interface: Utilizes a 7-inch touchscreen interface, providing visual menu operation. Print Output: Equipped with a modular integrated thermal printer, quick and easy printing of test results. Test Principle: Measurement of the force required to bend a test piece clamped at one end through a specified angle, normally 15°, where the force is applied at a specified bending length (50 mm or 10 mm). The bending resistance is calculated as a mean of the measured forces. Application; Packaging: Bending stiffness is important for ensuring that packaging materials maintain their shape and provide adequate protection to the contents. Printing: In printing processes, especially high-speed printing, paper with appropriate bending stiffness is desirable to prevent issues such as paper jams. Paperboard Products: Products like cartons and display boards benefit from having sufficient bending stiffness for structural integrity. Configuration: a) Standard configuration: WTD-01 Bending Stiffness Tester, paper roll, manual, calibration certificate, power cord. b) Optional configuration: standard weight, loadcell,
