It is tested to straighten stubs up to 145mm cold and 190mm diameter using induction heating. Impec has delivered a machine to Dubal which can handle stubs of 180mm by 250mm. It is the third machine with the same design after deliveries to Hydro Aluminium Aardal and Soral.
It is an automatic machine that consists of a hydraulic operated straightener, a silent induction heating system to heat up the stubs and a vision system for measurement and straightening of each stub individually.
This machine can be used for different stub size, and for different yoke configurations. The machine is module based so it can easily be modified if a customer decides to enlarge the stub diameter.
