Panel holes are widely used in the body and chassis of automotive cars because they aid to reduce overall weight, increase battery efficiency, and allow e-coat, surface prep, and primer to drain from the cavities during production.
They provide a concern because of how much noise they allow in. Butyl rubber solutions are useful in this situation. Due to their capacity to transform vibrations into heat and lessen noise that enters the cabin, butyl patches with foil backing are frequently employed to minimise noise and vibration.
Giving our consumers peace of mind has been largely a result of testing and validation. Echo Engineering closely collaborates with car OEMs to create and optimise our material to fulfil strict adhesion, sealing, and NVH damping requirements.
Butyl patches must be properly aligned in order for them to function as required. They are normally put by hand by assembly line employees.
Utilizing specially formulated butyl material that enables line workers to accurately remove and reapply the foil back patch is one approach to counteract this. At Echo, we’ve developed a method that allows assembly workers a window of time during which they can remove a butyl patch without leaving behind any residue and reapply.
Over the next hour, the butyl’s adhesiveness will increase, giving automobile manufacturers confidence that the patch will offer a seal that is more than just adequate.
The Global automotive NVH Butyl patch market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The field of measuring and altering the noise and vibration characteristics of vehicles, notably cars and trucks, is referred to as noise, vibration, and harshness (NVH), often known as noise and vibration, and abbreviated to N&V and N&V, respectively.
Harshness is a term that has been misused historically. While noise and vibration can be evaluated, harshness is a more individualized evaluation. A psychoacoustic measurement of harshness exists, however it does not strongly correspond with most harshness problems.
While external NVH primarily focuses on the noise generated by the vehicle and includes drive-by noise, interior NVH refers to the noise and vibration felt by passengers inside the car.
The improved operation of a vehicle has made noise, vibration, and harshness an essential concern. Vibration is strongly tied to the dependability and quality of the vehicle, whereas noise has an impact on the environment and the passengers. Harshness and the calibre of the vehicle are also related. Consequently, there has been an increase in the use of automotive NVH goods as a result of the increased desire for a quiet and secure environment during journeys.
