Bend and Impact Tester Model 471
The impact folding test allows you to assess the deformability of coated sheets after a sudden bending stress. The impact folding test simulates common sheet metal processing movements, such as punching, folding and flanging. The Model 471 bend-impact tester has a parallel guided impact hammer with a weight of 2300 ±100 g, and with a drop height of 650 ±5 mm. A specially shaped anvil serves as a support for the pre-bent sample plate. There is also a bending mandrel (5 mm diameter) on the base plate, on which the sample sheet for the impact folding test can be pre-bent.
