[0002] Affected by the shape of the interior dashboard and the 3Dmesh (3D mesh) manufacturing process, the 3Dmesh manufacturing process of the automobile dashboard needs to go through a hot pressing and cold pressing process. This process has restrictions on the shape of the dashboard. The dashboard cannot have a styling surface with a large curvature, which will cause the dashboard shape to be unable to increase its own strength, resulting in deformation or the hot pressing and cold pressing tooling cannot be assembled.

[0003] The current 3D mesh dashboards basically have large surface curvatures, which cannot have the large degree of design freedom of slush molding and injection molding dashboards, and have limitations on dashboard design.

[0004] During the processing of the 3D mesh instrument panel, the main body skeleton of the instrument panel will be subjected to huge closing pressure during the hot pressing and cold pressing stages. The special shape of the main body skeleton of the instrument panel makes the existing tooling unable to provide support for the main body skeleton of the instrument panel, and the cavity structure strength of the main body skeleton of the instrument panel is relatively weak. It is very easy to be compressed and deformed during the production process, which affects the quality of the instrument panel product.

[0005] The Chinese patent with application number 202210833533.2 discloses a microfiber leather covering process for an instrument panel, which belongs to the technical field of automotive interior instrument panels.

At the same time, the appearance of the coating is also shaped and the coating defects are repaired.
