Variable Edge Force Sheet Metal Forming Testing Machine

Variable Edge Force Sheet Metal Forming Testing MachineThe existing lightweight technology for automotive and aviation materials, research on sheet metal forming processes, testing of material physical properties, evaluation of welding processes, and grading of lubricating oils play a crucial role. Through our platform experiments, we can obtain design parameters and forming processes, reduce material waste in the industrial field, and achieve energy-saving and environmental protection effects.

The EC1200 sheet metal formability testing machine - fully automatic cup protrusion tester is a large tonnage sheet metal forming testing machine developed by Shanghai Jinbang Automation, which automatically completes the shearing, stretching, and forming of large-area sheet metal. The maximum shear force can reach 1200KN, which can shear thick plates with a diameter of 200mm. The ultimate tensile force of 1500KN can stretch various high-strength steel plates.
