CNC Machined Sand Cast Ductile Iron Differential Case

(Click on pictures to enlarge)

Both sand casting and CNC machining processes were employed to manufacture this flanged half-differential case. First, a rough cast of the differential case was made from ductile iron using customer's exact CAD data & prints. Features were then CNC machined through milling, turning, slotting, trepanning, and other operations. The case was finally assembled, washed, inspected, packed, and delivered to the customer. To make them corrosion-resistant, a rust preventative paint coating was also applied over the case. This differential case is widely used in front and rear ends of heavy trucks.
