Hot forming for larger diameters
All-in-one machines combine wire feeding from the coil, straightening and cutting, upsetting the head and rolling the thread in a single system and in one continuous process. Amba has now introduced a machine with wire diameters of up to 18mm/0.71inches that integrates inductive heating.
