Forging
Baseline Bolt makes use of National Upsetters in order to hot forge heads against bolts. In the course of the process, heating of the end of the round bar takes place through an induction process. It is then placed into the upsetter whereby a plunger tends to compress the heated steel in order to form the bolt’s head. To determine the exact amount of the round bar that will be reshaped, calculations are made. It is possible to forge the heads onto fasteners prior or following the threading process. well, upsetters have a clear advantage over the presses in the sense that there isn’t length limitation regarding bolts that are produced on an upsetter.
