Hot tops are essential refractory ceramic structures in the casting process, designed to ensure molten metal remains pure and free from impurities. Strategically placed on top of the mold cavity, they serve multiple purposes:
- Insulation: Keeps the molten metal hot, preventing premature solidification. 🚀️
- Pressure Equalization: Maintains even pressure for a flawless casting. ⚖️
- Filtering: Removes impurities for an immaculate final product. ✨
- Riser Extension: Provides a continuous flow of molten metal to the casting. 🚰
