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.

basic information
【Product Handling】 ■Wire Rod: The raw material is iron round bars. ■Cold Rolling: Processed into long steel materials with a rectangular cross-section using rollers. ■Bending: Coiled in a spiral while bending. ■Cutting: Cut into rings with an "overlap." ■Welding: Weld the cut sections of the rings. ■Trimming: Remove the parts that protrude as burrs. ■Heat Treatment: Heat to equalize the overall structure and strength. ■Shot Blasting: Remove scale attached to the surface. ■Straightening: Correct errors by applying pressure in a press machine to achieve a true circle. *For more details, please feel free to contact us.
