摘要： The specification discloses a patterned thickness article, a patterned injection molding, and a method for manufacturing the article. The injection molding has patterned internal surface including high-flow channels and a plurality of intermediate and/or lower-flow channels having varying cross-sectional areas within the injection molding. The method includes providing such an injection molding; providing a flow of molten material through a sprue and into the high-flow channels; creating a flow front in the injection molding that advances from the sprue along the high-flow channels and the intermediate and/or lower-flow channels; and applying a clamping pressure to said injection molding.

摘要： An acoustic fiber silencer for a motor vehicle includes a first sound absorbing layer and a second sound insulating layer. The layers are formed of lightweight fibrous material, and the sound insulating layer is quilted. The acoustic fiber silencer includes a frame to which the sound absorbing and sound insulating layers are secured. The frame provides structural support and shape to the sound absorbing and sound insulating layers. The acoustic fiber silencer is lightweight while maintaining excellent noise attenuation properties.
