डाई कास्टिंग के लाभ

Facing sand is a fine-grained material applied to the inner surfaces of a sand mold. Its primary function is to provide a smooth, impervious barrier to the molten metal, enhancing the aesthetic finish of the cast product. Typically, facing sand consists of silica or other fine materials mixed with various binding agents to improve its adhesion and durability. The choice of facing sand can significantly influence the outcome of casting operations.

The particle size of the abrasive significantly affects the machining process. Smaller particles yield finer surface finishes but may reduce MRR due to the limited cutting ability. Conversely, larger particles increase MRR but can lead to a rougher surface finish and deeper penetration into the workpiece material. Generally, an optimal balance of particle size is required to achieve specific machining goals.
