Crumple Flex Tester Comply ISO 7854 ISO 8069

Introduction:

Crumple Flex Tester Used for testing the flexing resistance of leather, rubber, plastic film, etc.

A rectangular test piece of coated fabric is sewn into a cylindrical shape .The cylinder of coated fabric is mounted between two discs and secured into position .One od the discs oscillates on its axis through approximately 90°。This induces twisting in the coated-fabric test piece cylinder. At the same time,the other disc reciprocates along its axis,thus causing the

Cylindrical test piece to compress along its length.The twisting and simultaneous compressing of the cylindrical test piece is continued for either a pre-set number of cycles or until damage to the test piece is apparent.

Equipped with acrylonitrile plastic cover for safe operation. `

Feature:

Design of transparent protective cover, when open the protective cover, automatic stop machine running.

With emergency stop switch for safety.

Samples are clamped, stable and durable, four-station linkage, greatly improving the test.

Efficiency.

Manual adjust disc position for easier installing specimen.

Circulating ventilation system to cool the instrument for long running time.
