All-in-One Bolt Manufacturing Machine: Hot Forming for Large Diameters
For the first time in the field of screw head forming, inductive heating is being used, which Aachener Maschinenbau (Amba) has integrated into its machines. The first machine in the new series will produce fastening elements between 160 and 1500 mm / 6.30″ – 59.06″ in length with diameters of up to 18 mm / 0.71″ directly from the wire.
Since very high forces are required when forming large volume heads, Amba is transitioning from cold to hot forming for the first time and integrating a system for inductive heating.
This machine produces square-head bolts used in power transmission applications and manufactured in quantities of millions. With this development, one customer has succeeded in replacing two older machines arranged in series.
