How to improve the rigidity and the strength of an injection molding part is a subject which is always explored in the automobile industry, an automobile is assembled by a large number of parts, the mode of a single part is improved, in a certain aspect, the mode of the whole automobile is improved, the performance of the whole automobile in various tests is further improved, and a solid and safe feeling is provided for a driver.

The injection-molded parts occupy a large proportion of both interior and exterior parts, and in the classification of interior and exterior systems, surface parts, which are parts visible to the naked eye, can be roughly classified into surface parts such as front and rear bumpers, radiator grilles, door panels, interior parts such as door panels, pillar panels, ceilings, instrument panels, and the like. Non-surface elements are parts that are hidden inside the surface element or are not visible in normal view. The inner liner is used as a supporting surface part, so that the inner liner is not easy to deform, and the inner liner achieves an ideal appearance form, or is called as a reinforcing bracket. To keep the surface element shape well, how to strengthen the lining support is the primary problem to be solved before.

According to the frequency formula: f-1/2 pi (k/m) ^1/2 yields that the frequency is proportional to stiffness and inversely proportional to mass, and that the frequency can only be increased if stiffness is much greater than mass, but this is difficult to achieve in practical situations.
