Aluminum Casting of Motor Housing/Shell

Aluminum die Casting of Motor Housing/Shell  is a part using aluminum alloy of ADC12, which has good liquidity, easy to fulfill the cavity of mold, it is a kind of Customized Aluminum Die Casting, the part is applied to automotive motor system, which is used to decrease the noise of the automotive while running, the part has requirement on the mechanical property. about Sunken,we should pay close attention  Feature: a concave part on the smooth surface of a casting, and its surface is naturally cooled. Causes 1, the casting structure design is unreasonable, there are local thick parts, produce hot knot. 2. High shrinkage of alloy. 3, the gate cross section area is too small. 4, lower than. 5, mold temperature is too high. Exclusion measures 1, to improve the casting structure, so that the wall thickness is slightly uniform, the difference between the thickness of the junction should gradually ease the transition, eliminate the hot knot. 2.
