Automotive interior products refer to automotive interior items, including interior sound-absorbing thermal insulation roof trim panels, side interior beams, doors, synthetic boards，rear side panels, and trunk floor panels. At present, the interior accessories made in China are mostly composed of two methods: one is to use engineering plastics or modified plastics to make sheets, and the leather, fabric, and other decorative parts are formed by hot pressing. The other is the introduction of models, the interior accessories are imported along with the main vehicle accessories.

This processing technology has the characteristics of low cost, fast modification, and small investment.
