Processes: Upset Forgings

These types of forgings usually require individual consideration as the process rules related to upsetting are limiting and have to be compared to process stages available and heater capacity.

However, for initial evaluation, the following information is a reasonable guide.

  • Max. length of forging 455m/m
  • Max. head diameter 130m/m
  • Max. bar size (original) 45m/m
  • Min. bar size (stock) 15m/m

Within these parameters various head forms can be offered, round, square, spider legged, yoke forms etc.
