The Finetech Engineering Bennewart flex tester manufacturer India evaluates the flexing endurance of thin vulcanised rubber components. Understanding what is flexing endurance rubber testing: it measures how many flex cycles a thin rubber section can withstand before cracking. While the Demattia flex tester handles standard-thickness specimens with a groove, the Bennewart is specifically designed for thin rubber sections (typically 2–4 mm thick) that bend through a large flexing angle.
Thin rubber components like shoe soles, diaphragms, thin conveyor belt covers, and flexible rubber joints undergo millions of flex cycles in service. As a leading footwear sole flex tester India and rubber flex endurance testing machine India, the Bennewart subjects thin specimens to repeated bending at controlled amplitude and frequency, counting the number of cycles until the specimen cracks or tears. A compound that survives more cycles has better flex endurance.
Finetech, a trusted IS 3400 rubber testing equipment manufacturer India, builds this IS 3400 flexing endurance tester rubber India to comply with IS 3400 and DIN 53522 – making it particularly relevant for Indian rubber manufacturers who need BIS compliance. It complements the Demattia flex tester: Demattia for standard-thickness specimens, Bennewart for thin sections.
Note: The Bennewart test is especially common in IS 3400 specifications for Indian rubber manufacturers. If your customer or BIS specification references “Bennewart flex,” this is the instrument you need.

The answer to “what is Bennewart flex test rubber”: it evaluates the flexing endurance of thin rubber specimens (2–4 mm thick), counting the number of flex cycles until the specimen cracks or fails. Higher cycle count = better flexing endurance result. Specified in IS 3400 and DIN 53522.
On the question of Demattia vs Bennewart which test for rubber sole: Bennewart is for thin rubber sections (2–4 mm), bending through a large angle – correct for footwear soles. Demattia is for standard-thickness specimens (typically 6 mm or more) with a groove as a stress concentrator. They test different thickness ranges and flex geometries.
IS 3400 (Indian BIS) and DIN 53522 (German) are the primary standards. If your specification says "flexing endurance per IS 3400" for thin rubber, the Bennewart is the correct instrument.
Yes. As a certified Bennewart flex tester manufacturer India, Finetech provides calibration certificates for cycle speed and flexing angle.
