Abstract

The invention provides a manufacturing process of a TPU-based high-performance automobile instrument panel. The process comprises the following steps of selecting industrial-grade equipment suitable for selective laser sintering (SLS) of a polymer material for molding; designing a three-dimensional model of each split body of the assembled automobile instrument panel; taking TPU powder as a base material, adding impact-resistant, anti-exposure and functional fillers, and conducting mechanical mixing to prepare functionalized TPU composite powder; setting process parameters of SLS, carrying outSLS forming on the mixed powder, and printing a standard spline; performing performance test on the printed standard spline; and forming the automobile instrument panel (split), conducting sand blasting, powder removing and other treatment on the automobile instrument panel (split) obtained after SLS forming, and finally conducting splicing to obtain a finished product. The process for forming the TPU-based high-performance automobile instrument panel through the SLS is easy to operate and high in flexibility, and the formed automobile instrument panel has good impact resistance, insolation resistance and the like and is wide in application prospect in the field of automobile industry.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a manufacturing process of a TPU-based high-performance automobile instrument panel. Background technique [0002] The car instrument panel is the frame for installing the car instrument. Usually the car instrument panel is assembled, that is, it is assembled from various parts. Among them, the middle part is a thin-walled and large-volume component with complex shapes with many holes and holes for installing instruments, and the two side parts are composed of two thin plates. The instruments of different cars are not the same. The conventional instruments of ordinary cars include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, etc. Therefore, the shape and structure of the car instrument panel are complex, and it needs to meet certain impact resistance and sun protection. performance. [0003] According to the existing tr...
