Producing a high-performance shell for a vehicle motor requires a combination of heavy industrial casting and extreme precision machining. The process begins in a foundry, where raw aluminum alloy ingots are melted down in a high-temperature furnace. This molten metal is then injected into a reusable steel mold under extremely high pressure. This die-casting method creates the rough shape of the Automotive Motor Housing, including the exterior cooling fins and the internal cooling channels. Once the metal cools and solidifies, the rough casting is removed and sent to the machining department.
The next phase is where the tightest tolerances are achieved. The cast part is mounted onto a vertical or horizontal CNC machining center. Programmed cutting tools shave away millimeters of metal to create a perfectly round interior cavity for the stator. The machines also drill and tap the bearing positioning holes and mounting brackets. Because any misalignment can cause motor vibration, the final Automotive Motor Housing must be inspected using Coordinate Measuring Machines (CMM) to verify that all dimensions match the original CAD drawings down to the micrometer before it is approved for assembly.
