bennewart-flex-tester1

During the entire life cycle, footwears go through continuous flexural cracking and fracture. The Tension produced on the soles result in these cracks and fracture. Extreme pollution (with the presence of high amount of oil) and temperatures (mainly below zero) also accelerate cracks on the soles. Hence, Keeping in mind the quality of a product, Bennewert Flex Tester is used to enhance the life of a footwear and to check the crack resistance of a rubber product used to manufacture the footwears.

The Bennewart Flex Tester allows to determine the resistance of rubber products to the growth of a cut during repeated flexing. The machine is also known as a Rubber Flex Tester, mainly used to test the resistance of soles of shoes. The machine is designed for the assessment of entire bottom construction of a shoe that includes insoles and midsoles and is used to comply with testing parameters as specified in various domestic and international standards.

One of the best range of Presto’s rubber testing instruments include Bennewart Flex Tester.
