Automobile rearview mirror assembly/material/appearance requirements are fully resolved 2019-05-30

As we know, the rearview mirror is divided into outer rearview mirror and inner rearview mirror.


A typical external rear-view mirror is composed of nearly 20 parts, among which plastic materials are mainly used in the rear-view mirror case, mirror case base, bracket and triangle plate.

These pieces play a different function or appearance, the performance requirements of the material are different, and then we give a detailed description of its material selection.


01

Rearview mirror housing


Rear-view mirror shell is generally designed to be the same color of the body, and most of them are high-gloss effect, so most of them are sprayed, and a few electroplating schemes can also be adopted to reduce the pressure of environmental protection.

02

Mirror shell base

The mirror housing base plays an assembly and transition role, so ASA or PP+MD is preferred.

Rearview mirror holder


The rear-view mirror bracket mainly plays a supporting role, requiring high rigidity, good appearance, good weather resistance, can choose metal parts, plastic parts or metal and plastic combination, most choose aluminum alloy, PA+GF or PBT+GF.

The triangle plate of the rear-view mirror is the part connected with the car window, which is mostly formed with the rear-view mirror bracket. If it is formed separately, the selected materials are metal, ASA or PC/ASA.


Above are the material selection and characteristics of the external rearview mirror.
