Beschreibung
Zusammenfassung:	The invention relates to a production method for a low-weight automotive carpet lower acoustic shock pad and belongs to the technical field of automobile part production. The method includes the surface layer laying step, the surface layer baking, warming and softening step, the surface layer adsorption forming step, the surface layer water jet cutter cutting step, the base material laying step, the base material baking and warming step, the compression forming step and the water jet cutter cutting step. The low-weight automotive carpet lower acoustic shock pad produced through the method meets the requirements for the performance indexes such as sound insulation, shock absorption, environmental protection and low weight; the weight of the carpet lower acoustic shock pad is greatly reduced, and the requirement for low weight design of a whole automobile is met; thermoplastic felt is selected, so that the cost of a raw material is reduced, and selectivity is higher; EVA is additionally arranged on part of the
