Patented method of producing battery bushings

Battery terminals as supplied by HOFMANN POWER SOLUTIONS are manufactured in a specially developed production process that has been perfected over the years. The result is an extremely hard, highly compressed pole with unique optics and perfect undercut design. Our arrowhead-shaped, self-sealing labyrinth rings ensure a firm connection between the battery bushings and the polypropylene of the battery cover.

This special form of the so-called undercut labyrinth causes the plastic to shrink during lid manufacture and thus creates an optimum seal between the battery bushings and the battery lid, which prevents the escape of acid and gases.
