Hooded Crucible:
  • Design: Enclosed or partially enclosed with a small opening or spout.   
  • Primary Use: Generally recommended for precious or semi-precious alloys and those with lower melting points. The hood helps to:
  • Retain heat more effectively: This can lead to faster and more energy-efficient melting, especially for smaller quantities of metal.
  • Minimize oxidation: The reduced exposure to air helps prevent the formation of oxides on the surface of the molten metal, preserving its purity and reducing material loss.   
  • Reduce splashing: The enclosed design helps contain the molten metal during the centrifugal casting process.
  • Pouring: Pouring is typically done through a designated spout or the main opening.
Slotted Crucible:
  • Design: Open with one or more vertical slots along the side.
  • Primary Use: Often preferred for non-precious alloys and those with higher melting points. The slotted design is thought to:
  • Improve alloy flow: The slots may facilitate a more even and less turbulent flow of the molten metal into the mold during centrifugal casting.
  • Offer better visibility: The open slots allow for easier visual inspection of the melting process.
  • Potentially handle larger volumes: Depending on the design, slotted crucibles might be better suited for larger quantities of metal.  
  • Pouring: The molten metal exits through the slots during the centrifugal force of the casting machine.
