Our client is a major cosmetics company using a variety of brushes for all applications and wished to tensile test the integrity of the bristles.

Gripping the awkwardly-shaped handles and bristle tips in a repeatable way, demanded more than a single standard vice grip.

Mecmesin designed a system of overlapping plates with cutouts for each brush head profile. The plate served to gather and trap the bristles uniformly in a vice action so that they were axially aligned under the loadcell.

A lathe-chuck grip held the handle securely for reliable and accurate pull-off testing.
