    2020-5-27 · Bolts Manufacturing Process Cold Forging: This initial process is a cold forging process used to produce a near net shape work billet. An important consideration in cold forging is the tendency for the bar to buckle if its unsupported length to diameter ratio is too high. This ratio usually is limited to less than 4:1 but with suitable dies, therefore, cold forging is the most likely
