Advanced Sheet Metal Forming Testing for Accurate Material Analysis

The BMT-STA Sheet Metal Forming Test Machine helps manufacturers and research laboratories analyze how sheet metal deforms under complex loading conditions. Equipped with optical strain measurement technology, the system captures strain distribution in real time and generates highly accurate Forming Limit Diagrams (FLD).

This sheet metal forming test machine is ideal for evaluating steel, aluminum, stainless steel, copper and advanced high-strength alloys used in automotive, aerospace and metal processing industries.
