Card and paper crease line testing

Customised engineering example

A packaging production company needed to test the crease force of the ink-coated card used in their fully-enclosed cartons. This required accurate measurement of the folding movement by the cantilever bend method. Their budget was limited and they wanted a simple tester, so a manual test system was developed to provide a very cost-effective solution to their requirements. 

Mecmesin designed a customised fixture to manually rotate the gripped card against a compression bar attached to a 100 N digital force gauge. Clickstops, at fixed angles of 45 and 90 degrees, allowed the folding force to be recorded consistently at each angle for various card materials.
