Aluminum Die Casting Transmission Housing

Aluminum Die Casting Transmission Housing, it is an auto part, which is applied to transmission system, it the housing of the automotive gearbox. The estimated annual usage is 250k pieces. Theoretically for such large demand, the cavity number of the mold for this part should be more than 2. However, considering the irregular shape, the part has two slides, what's more, this part has very strict porosity request, also require leak test by air. In order to ensure the density of the part, the cavity number is only 1.  As an experienced die casting manufacturer, we ran solidification analysis to simulate the status of the filling of the melting aluminum to look into if the design of the mold is proper or not, such as the location of the injection gate, runner, overflow gate, slag strap, venting slot, ejector pins etc.  Then, prior to the fabrication of the tooling, the CAD model of the design will be sent to the customer for confirmation, to…
