Dongguan CNC processing plant For semi centrifugal casting parts, may be more complex than those centrifugal casting parts, but in essence is axisymmetric. This method does not need a core to obtain a central hole. The sand mold or metal mold revolves around a vertical axis, and the liquid metal enters the mold through the central casting area, as shown in Figure 11.13: for high productivity, the molds in Dongguan CNC processing plant can stack up with each other to replenish the liquid metal from the same central casting area. In this process, the rotation speed is not as large as that of centrifugal casting.

When the shape of the casting is not axisymmetric, centrifugation is often used to obtain higher cooling rate in the solidification process. But this method is only suitable for making small castings of any shape. A large number of such small castings in Dongguan CNC processing plant are combined by the radial rotor of the center gate on the rotating disc, as shown in Figure 11.14. The small castings are arranged on the periphery of the disk to ensure the balance of the large parts. This process is similar to that of semi centrifugal casting.
