3. Electrical Discharge Machining (EDM) EDM is another advanced technique that utilizes electrical discharges to remove material from the workpiece. This method is especially advantageous for hard ceramics that are difficult to machine through traditional means. EDM is capable of producing features with high accuracy and is often used in applications requiring detailed shapes and fine tolerances.

1. Silica Sand This is the most commonly used sand in foundries due to its availability and excellent thermal properties. It can withstand extreme temperatures without breaking down, making it an ideal choice for ferrous and non-ferrous metal casting.

2. Material Selection Choosing the right grade of carbide is vital. Different grades offer varying levels of toughness, wear resistance, and brittleness. Engineers must select a material that aligns with the intended use of the die and the type of metal being processed.
