3. Wax Removal After the shell has hardened, the wax is removed through a process called dewaxing. This can be accomplished using heat or steam, which melts and drains away the wax, leaving behind a hollow ceramic shell that mirrors the exact external shape of the desired aluminum part.

While aftermarket parts can be significantly less expensive than OEM components, they often come with potential downsides. Many aftermarket manufacturers do not adhere to the same stringent quality standards as OEMs, resulting in variable quality. Furthermore, compatibility issues can arise, leading to increased repair costs and reduced vehicle performance. In some cases, using aftermarket parts may void warranties provided by the vehicle manufacturer, creating potential long-term costs that outweigh initial savings.

1. Precision and Accuracy The primary advantage of CNC sand casting is its ability to produce high-precision parts. The use of CNC machines ensures that the molds are created with exact specifications, minimizing variances and inaccuracies that can occur with manual molding.
