Metal Ring Manufacturing Technology "Bender Method"

High quality, high yield, and low cost are its features!

The "Bender Method" is a manufacturing process for metal rings that utilizes cold bending and welding techniques. After cold rolling round steel into long steel materials, it is bent to a specified diameter, then spirally bent and stacked, cut into individual pieces, and welded to form a true circular ring. The yield of raw materials is 95%, resulting in minimal material loss. In the process of forming true circular rings through cold rolling → bending → cutting → welding → heat treatment → straightening, the Bender Method finishes metal rings with a roundness of within 0.5mm. *For more details, please feel free to contact us.
