Paper Core Radial Crush Strength Tester

Motorised compression tester that squeezes paper cores and tubes between flat platens to measure radial crush load and deflection. Used by core makers and textile, film and paper converters.

Specification

A paper core is laid on its side between parallel platens and compressed at constant speed while load and deformation are recorded. The peak load indicates how well the core resists clamping and winding pressure. Test data helps tube makers tune wall thickness and board grade.

Features

• Constant platen speed 12.5 mm/min
• Load cell capacity 5 kN with peak hold
• Platens 400 mm wide for cores up to 400 mm long
• Displacement sensor with 0.01 mm resolution
• Overload protection and limit switches
