Insulating Open Sleeves ideal for clean, efficient feeding in iron castings where heat retention (not generation) is needed
Key Features:
- Open-Top Configuration
- Molten metal enters from the top during pouring.
- Simple mold setup — often used in vertical or flask riser applications.
- Helps improve casting integrity without compromising mold layout.
- Insulating Material (Non-Exothermic):
- Composed of low thermal conductivity refractory materials
- Retains heat in the riser metal without any combustion or fume generation.
- Filter inserts for slag control
- Optional Add-ons:
- Hot-topping covers/lids
- Collars or height extenders
- Filter inserts for slag control
