Cabin noise reduction has become a top priority for automotive manufacturers as demand for Electric Vehicles increases. Parasitic sound erodes the customer's experience & brand luxury. Coverage of panel holes has become a necessity, and one of the top solutions used by EVs has become panel plugs.
There are many holes in an automotive chassis. These serve to achieve lightweighting targets; allow e-coat, surface prep, and primer to drain from the cavities during production; and provide access points for downstream assembly and service. However, they also increase the propagation of sound and vibration as well as provide a pathway through which moisture can travel.
Echo’s engineers are skilled at designing panel plugs that minimize installation and removal forces without compromising the sealing and NVH capabilities of our panel plugs. Our panel plugs are also designed to work with a range of panel thicknesses – meaning fewer SKUs can cover a wider range of holes.
Our custom solutions allow us to create complex seal geometry that is way beyond a typical slot or hole. And don’t worry about panel flatness. We can design plugs to fit whatever geometry you have.
