Cold formed parts are created by applying extreme force to metal blanks. In a multi-step process, the blanks are pushed through a series of predetermined punches and dies designed to obtain the part’s required shape. Each step makes a slight variation to the blank, and after many stages and additional secondary processing, a completed fastener is revealed to specification.
Production of cold formed parts is quick and inexpensive because the process results in virtually no metal waste. The process also results with final products being of higher tensile strength than the original blank. Like machining, cold-forming can also be extremely accurate with tolerances as low as .001" in diameter and .005” in length. While various metal and alloy materials can be used in the process, the decision will often be made based on the end-use performance requirements of the part.
Because of its comparatively low production costs and the introduction of new technologies, cold-forming is often being used in instances where screw machining was traditionally chosen. Improvements in tolerances and shaping capabilities, combined with advances in deburring, cleaning and sorting technologies, make cold-formed parts a highly-compatible alternative.
