Cast Products Inc., Norridge, Ill., created a new design for Gentex rearview mirror mounts used in Volvo Autos and SUVs. Zinc gives the mounts good wear resistance and tensile strength. It also easily molds the necessary thin-wall sections. The casting was designed around the mirror mount's humidity sensor to make the smallest possible footprint. This windshield-to-mirror head transition housing eases the mounting of the sensor and related wiring and harnesses. This is important because rearview mirror assemblies are the preferred location for advanced electronic features, such as climate control and automatic dimming to eliminate nighttime glare.
