Abstract
A method to form automobile vehicle acoustic insulators includes as stages: forming a fiber mass by mixing a low melting point polymeric fiber and a high melting point polymeric fiber in predefined volumes in a mixing device; adding a water volume to the fiber mass to create a semi-solid mass; placing the semi-solid mass in a mold; internally heating the semi-solid mass in the mold using microwave energy; and expelling a first portion of the water volume through apertures created in the mold.
