Compound applications apply material to the curled area of the can end, which cures into a rubberized gasket. This compound application creates a reliable seal between the can end and can body, minimizing the potential for leakage and preserving the integrity of the product.

Nordson systems use a patented A11A Can-End Lining gun to apply the compound material as the end rotates. The gun features a zero-cavity, needle-and-seat designed nozzle for fast, clean cut-off. It also incorporates a detent adjust control for the very fine adjustments required in exacting end-lining operations.
