Abstract

The invention provides a production technology of an automotive headliner capable of being provided with an invisible microphone, and belongs to the technical field of production of automotive interior parts. The technology comprises the following steps: raw materials of all components of the automotive headliner are placed in a hot die cutting mold, and undergo compression molding to obtain a semi-finished automotive headliner substrate after the molding is finished; the invisible microphone hole site of the semi-finished automotive headliner substrate undergoes water knife cutting treatmentto obtain a finished automotive headliner substrate after the water knife cutting process is finished; a fabric is placed in a laminating mold, and is laminated to obtain a semi-finished automotive headliner; and the semi-finished automotive headliner is subjected to secondary water knife cutting treatment to obtain the automotive headliner after the water knife cutting treatment is finished. Thetechnology has the advantages of simple steps, convenience in operation, increase of the production efficiency, and ensuring the appearance consistency of the top lining fabric.

Description

technical field [0001] The invention belongs to the production technology of automobile interior parts, and in particular relates to a production technology of a car roof capable of installing invisible microphones.
