3. Conducting Tests Implementing trial runs can be beneficial to determine how well parts are ejected and whether the current draft angles are sufficient. Iterative testing can help fine-tune both angles and design features.

One of the major advantages of sand casting is its cost-effectiveness. The materials used are inexpensive, and the molds can be reused for multiple casts, reducing waste. This aspect is particularly beneficial for small production runs where the investment in expensive tooling would not be justified. Additionally, the sand casting process is relatively straightforward, which means that even small businesses can set up their operations with limited overheads.

Milling involves the use of rotary cutters to remove material from a workpiece. Unlike turning, where the workpiece is rotated, milling machines hold the workpiece stationary and move the cutting tool across its surface. This process allows for the creation of complex shapes, slots, and holes. Milling can be categorized into two main types vertical milling and horizontal milling, depending on the orientation of the cutting tool. It is widely used in the manufacturing of molds, fixtures, and intricate mechanical components.
