Description:
The award was given to a housing cup and lid used in an audio device with magnetic shielding capabilities. This application is the first of its kind in the high-power audio device sector. The anti-magnetic MIM material with high nickel content provides an electromagnetic interference, or EMI, shield, preventing interference from other electronic equipment. While the cup has four thin walls for proper assembly, the new lid design must fit securely into the cup opening; this is to prevent moisture and/or foreign matter from entering the housing, as well as to maintain the EMI shielding capability. Manufactured to 8.30 g/cm³ density, the parts have an ultimate tensile strength of 84,000 psi, yield strength of 32,000 psi, and a 40 percent elongation. Alternative manufacturing processes such as deep drawing, casting, and machining would have required multiple components. Combining these multiple components through the MIM process provided significant cost savings, in addition to eliminating up to 40 percent scrap loss.
