After the successful installation of 4 magnetic stackers with pushers, Gonvvama achieved in 2021 a production milestone of 2 million door rings produced, and more than 140 million of blanks stacked.
This magnetic stacker technology enables using the blanks also for laser welding, as the edges are not in contact with stoppers or centering elements. Moreover, it can stack both exposed and structural blanks thanks to the multimode technology that allows working in Continuous and Start-Stop modes.
Multiple Stacking Combinations
The stacker is able to process different blanks being cut at the same time and enables multiple stacking combinations depending on the selected recipe: Left & Right blanks in the same pallet or Left blanks in one pallet and Right blanks on another pallet, up to 32 stacks per pallet following a 8×4 stacking matrix.
High Stacking Precission
Thanks to the fact that these stackers do not use stoppers, they provide a high flexibility to produce and stack different shaped/geometry pieces. Moreover, this state-of-the-art stacker allowed high accuracy since the blanks are stacked with a precision of ± 2 mm.
