Abstract
A vehicle sound insulation component comprising a sound barrier layer where foam is introduced to both sides of a sound barrier layer and where the foam can be configured to follow and accommodate various three-dimensional contours within the sound barrier layer. The foam can therefore replace the need to utilize sound absorbing fleece material.
Claims14
A method producing a vehicle sound insulator component comprising:
- a. providing a first mold portion and second mold portion;
- b. providing a sound barrier layer having one or a plurality of openings for passage of a foam precursor, said one or plurality of openings define an opening area in the range of 1.0 cm2 to 10.0 cm2;
- c. placing the sound barrier layer between the first mold portion and second mold portion and closing the mold wherein the sound barrier layer is gripped between said first and second mold portions and defines a first lower cavity and second upper cavity each having a cavity thickness in the range of 0.1 mm to 50.0 mm;
- d. injecting a foam precursor into said first lower cavity and through said one or plurality of openings into said second upper cavity;
- and
- e. forming foam in said first lower cavity having a thickness in the range of 0.1 mm to 50.0 mm and forming foam in said second upper cavity having a thickness in the range of 0.1 mm to 50.0 mm, wherein said foam has a density in the range of 35 g/dm3 to 95 g/dm3.
