I. purpose:
This machine is suitable for the flexural resistance of soles and other materials.
Ii. Principle:
The specimen is guided with one end fixed and the other may be bent to 90° around a circular axis with a radius of 15mm.
Before the test, a specified cutting knife is used to Pierce a cutting edge at the zigzag point of the shoe. After the test, magnifying microscope is used to check the folding resistance of the sole.
The testing machine meets the standards of en-344, SATRA TM161, iso-20344, GB/ t20991-2007, etc.
