Case study
Split mandrels for closure torque testing
Customised engineering example
Smooth surfaces of twist caps, used on bottles and jars, require enough gripping force to avoid slipping during a torque test but without creating distortion in the cap.

Case study
Pharmaceutical tablet crush and break strength
Requirement
Many products come in tablet form, with a durability designed for both packaging and for use. Too brittle or too hard, and they may not be fit for use, or at best perform below expectation.

Case study
Bottle cap torque testing with custom mandrels
Requirement
A key element, when measuring the opening and closing torque characteristics between a bottle and its cap, is to minimise any distortion of the closure by gripping evenly and uniformly.
58
Case study
PCB pull and shear test
Requirement
A printed circuit board manufacturer wanted to perform both pull and shear tests of surface-mount solder joints according to IEC 62137-1-1 and -2 standards.
