What is Cold Forming?
Cold forming is a high speed forging process where coiled wire at room temperature is precisely sheared to length, and then moved through a succession of tool and die cavities to displace the working metal, either larger/smaller in diameter, longer/shorter in length, or to remove small amounts of material by trimming or piercing.
Using raw material with the same diameter as finished product, pipe is pushed through a die and formed into its desired shape. Usually applied to stainless steel, small to medium sizes.
