5. Production Volume High-volume production often justifies the expense of custom tooling, while lower volumes may benefit from alternative methods, such as laser cutting or CNC machining. This consideration is critical when designing parts intended for mass production.

3. Tooling Longevity The presence of a draft angle can directly impact the longevity of the die casting tooling. Reducing the force required to eject parts minimizes wear and tear on the mold, thus extending its operational life. Tooling is one of the most significant investments in die casting, so maximizing its lifespan offers considerable cost savings.

To hold the sand together and create a sturdy mold, binders are mixed with the sand. The most traditional binder is clay, often used in green sand casting processes. Bentonite clay is the most common type, as it swells when wet and provides excellent mold strength. Modern sand casting may utilize chemical binders like phenolic resins or water-soluble binders, which harden upon heating or curing. These advanced binders allow for finer mold details and improved surface finishes, facilitating more intricate designs in the final products.
