challenges brought about by work.

1. Equipment working principle:

The working principle of the catheter torsional strength tester is mainly based on the measurement of torsional moment and torsion angle.Under test

During the test, the catheter to be tested is fixed on the fixture of the tester, and a certain amount of twisting is applied through a high-precision motor.

Moment causes torsional deformation of the conduit.At the same time, the tester will record the changes in torsion moment and torsion angle in real time.
