Sand casting and permanent mold casting each serve an important purpose — the key is knowing when to use them. Sand casting is typically used for lower production volumes, prototypes, and larger parts. Permanent mold casting uses reusable steel molds and controlled pouring to achieve tighter tolerances, smoother surfaces, and higher consistency at moderate-to-high volumes. Choosing the right process early can reduce machining, improve quality, and save cost over the life of a part. 🎙️ From Cast
