Abstract

The invention relates to a method for producing a roof sun visor of an automobile. The method is characterized by adopting the following process sequences: preprocessing basal body PU material: including roll gluing, softened water spreading and the combined laying of materials for the roof sun visor; pressing the laid materials in a mould so as to form a semi-finished product; carrying out vacuumadsorption cooling molding on the semi-finished product formed by pressing; and then carrying out water cutting on the cooled and molded semi-finished product. The invention can greatly reduce the weight and achieve high rigidity without breaking and sagging; and besides, the invention can greatly reduce the labor intensity of workers in the process of production without generating harmful substances in the process of production and can increase the production efficiency.

Description

technical field [0001] The invention relates to a production method for making automobile sunroof sunshades by rolling PU rubber. Specifically, the automobile sunroof sunshade is a sunroof mechanism installed on the top of a sunroof car, which plays the role of heat insulation, sound insulation and beautification, and belongs to automobile The field of interior technology. Background technique [0002] The car sunroof sunshade is installed on the sunroof mechanism on the top of the sunroof car, which plays the role of heat insulation, sound insulation and beautification. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as high sound absorption, low wei...
