Vamp Flex Tester

Vamp Flex Tester Low Temperature Model

Approx Price: Rs 1.4 Lakh / Unit 

The Vamp Flex Tester is used for assessing the tendency of shoe uppers and lining materials to crack or fail at the flexing creases formed in the upper during walking.

 

In this test, square shaped test specimens are held at their opposite edges in two inverted V-shaped clamps having their holding faces in the same plane. One of the clamps is kept fixed while the other is made to move towards it and back repeatedly, producing cracks similar to those formed in the vamp of the shoe. This process is repeated continuously and the condition of the test specimens checked after different specified number of flexing cycles till failure occurs. For conducting resistance to hydrolysis the test specimens are conditioned in saturated water vapour atmosphere by keeping them in a dessicator above water for seven days at 70°C, followed by conditioning under a standard temperature for 24 hours before conducting the flexing test at -5°C.
