earphone housing for 3C and IT electronics is made of Stainless steel, formed bymetal injection molding from BRM company. earphone housing is also known as sensor case, developing based on years of independent research and manufacturing experience of earphone housing. earphone housingcan be tailored or custom-made in-house through our company. BRM can also manufacture more similar products like headphone metal button and provide one-stop service. Under metal injection molding, the tolerance of Stainless steel earphone housing can be reached ±0.05 and the dimension of the manufactured parts can be near the net shape. In 3C and IT electronics , metal injection molding is often used to produce earphone housing. In combination with user demands, metal injection molding is optimized and innovated on structural design, equipment configuration and combined application, so as to realize more flexible combinations, earphone housing is greatly applied in not only in 3C, but also IT electronics. Stainless steel is mostly common materials in metal injection molding. Different grades ofStainless steel can also be used in this technology such as SS316L, SS304L, 17-4PH, SS440, SS430, SS420, SS410, SS305
