Material bending resistance testing machine

Product introduction of flexural strength tester:

Mainly used to test the folding resistance of sheet materials such as paper, cardboard, copper foil, aluminum foil, plastic film, and flexible circuit boards (FPC) with a thickness of less than 1mm. This device quantitatively evaluates the bonding strength, flexibility, and durability of its internal fiber structure by simulating the repeated bending of materials during actual use, processing, and circulation. ‌
