Abstract

The invention relates to a producing method of an automobile skylight sun louver, and belongs to the technical field of automotive upholstery. The method includes the steps of preprocessing a base body PU material, combining and laying a skylight sun louver material, conducting pressing and forming, conducting cooling and shaping, and conducting cutting through a water jet scalpel, wherein the step of preprocessing the base body PU material includes the substeps of rolling the material in rubber and spraying softened water. By means of the method, the high strength performance index of a skylight sun louver assembly is achieved, the requirement for high strength design is met, the assembly line work of heating double-sided PU, rolling the PU in rubber and conducting processing through the softened water is adopted in the PU material preprocessing step, the process is stable, operation safety and accuracy are ensured, and meanwhile the work efficiency is improved; the product is high in rigidity, no breaking or drooping can occur; no semi-finished products are accumulated in the way, bad products caused by insufficient rigidity are reduced, and the manufacturing cost is saved; no harmful substances are produced in the whole producing process of the product.

Description

technical field [0001] The invention relates to a production method of an automobile sunroof sunshade, in particular to a production method of a double-layer PU sunroof sunshade installed on the automobile sunroof mechanism, which plays the role of heat insulation, sound insulation and beautification, and belongs to the automobile interior Trim technology field. Background technique [0002] Car sunroof sun visors are generally installed at the car sunroof mechanism to play 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, the high-strength performance index of the sunroof sunshade has become a bottleneck, which res...
