Flexing Tester

Presto’s Ross Flexing tester is designed to check the resistance of vulcanized synthetic elastomers to check the flexing intensity. It is an important parameter to check the quality of a shoe sole is its capability to resist repeated bending practiced during walking, without developing a break within the expected life span of the shoe heel. Presto’s Ross Rubber Flexing machine strictly adheres to ASTM method D1052 and ISO 4643. Rubber products subjected to recurring meandering. The products inclined to develop cracks and strains at right angles and slowly become too fragile to use. Hence, it is important to estimate the strength of rubber goods against repeated bending.
