Ring blank manufacturing process with the Benda Method

The Benda Method is a process for manufacturing metal rings using cold-bending processing, welding, and other technologies.
Round steel is cold-rolled into long steel material, bent into a predetermined shape, and then bent in layers to create a spiral. Then, each spiral is cut, welded, and formed into a perfectly circular ring.
Refinements and improvements to this process over many years has led to the establishment of high-quality, high-yield metal ring manufacturing technology that produces an extremely small amount of material loss (scrap).
