In Collaboration with Doli, Qualitest offers the full automatic Flexometer, commonly known as "Goodrich Flexometer" which has been manufactured since 1985.
The automatic Flexometer system features height measurement and cooling stations, an automatic temperature chamber including preheating station and a specimen silo for 20 specimens.
The Compression Flexometer is used as testing instrument in the rubber industry. Especially producers of fillers (carbon black etc.) and the tire industry use this type of Compression Flexometer. The test is based on the standards ASTM D 623 , DIN 53 533, part 3 or ISO 4666.
This dynamic test (performed using weights and a beam of balance) is fixed at 30Hz and working with a constant load.
The following results can be obtained:
The heat built up (detected via the contact temperature at the lower platen,).
The specimen deformation as well as the temperature in the centre of the specimen.
A puncture needle measures the temperature directly after the test, with the specimen still being inside the Flexometer.
We also offer special molds for producing specimens.
