Body Buckling

By the looks of things, this can got straight up smooshed in the seamer. This can on the left came from a brewery that had recently switched can suppliers, and although the general size of the can was the same, the exact specs for pin height were not referenced before the run. Pin height is the measurement between the raised lifter pad and the chuck. We will also see this type of damage when the spring pressure in the lifter is set too high, in essence slamming the can into the chuck and crushing it. Lastly, body buckling may occasionally be caused in the filler when the snift times are set long while the limiting nuts are set too high.
