The invention discloses a sound insulation and heat insulation pad of an automobile. A production process of the sound insulation and heat insulation pad of the automobile includes the steps that a base material is heated at high temperature through a two-stage oven, hot-melting felt is heated at high temperature through a one-stage oven, the heated base material and the heated hot-melting felt are continuously put into a mould to be subjected to compression moulding forming together, meanwhile, punching of part of holes is completed, and then a semi-finished product is obtained, wherein the high temperature is 280-380 DEG C; the semi-finished product is cut through a water jet cutter to form the needed product. Production efficiency is improved, the fund input of mould equipment is lowered, product stability and uniformity are improved, safety and environmental friendliness are achieved as no solvent adhesive is used, the rejection rate and production cost are lowered, and the sound absorption, sound insulation and heat insulation properties are excellent.
