Introducing the Bend and Impact Tester Model 471
Offering unparalleled precision in assessing the flexibility and impact resistance of light-gauge sheet metal, tube stock coatings, and more, the Bend and Impact Tester Model 471 by Erichsen is a must-have tool for modern manufacturing. Ideal for simulating real-world stresses like punching, beading, and crimping, this device ensures your materials can withstand the demands of today’s industrial processes.
Advanced Design and Functionality
The model 471 features dual vertical tubes guiding a 2300 +/- 100 g impact tool with a precise 650 mm +/- 5 mm drop. It includes a specially designed anvil for test panel placement and a 5 mm diameter rod mandrel for exact bending of the coated panel on its base plate. This innovative setup allows for a comprehensive test of material durability under prescribed impact forces, squeezing the metal into a conical shape to assess bending radius and coating failure points.
Comprehensive Testing Procedure
The coated sheet metal panel, measuring 50 x 140 mm, is bent 180° over the mandrel with the coating outside. After positioning the panel on the anvil and releasing the impact tool, the device simulates extreme bending stress. Subsequent evaluation in a specialized solution reveals any coating failures, visible as lines or dots of corrosion, providing valuable insights into the material’s formative qualities.
What’s Included
The package includes the Bend and Impact Tester Model 471, complete with bending mandrel, empowering businesses to achieve new standards in material resilience and product quality.
