Sudhir Fasteners houses cold forming capabilities for products ranging from 3mm to 14 mm in cross section. 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. Metal is forced beyond its yield (elastic) limit and retains its altered shape upon removal from the die. This technology has evolved over the years and is typically used in the large scale manufacturing of fasteners and certain other engineered products used in automotive, construction and industrial markets.
Advantages of cold forming
- Over 50% reduction of energy consumption and CO2 emissions
- Superior technical end-product quality
- Higher product output per minute (up to 300 products per minute)
