Highly Insulating Oval Neck Down Sleeves ideal for space-efficient and clean riser feeding in iron and steel castings:

Key Features:

• Oval Shape
  • Designed for tight mold spaces or elongated feeding zones.
  • Feeds a wider surface area compared to circular sleeves.
  • Allows for multi-sleeve placement in close proximity.
• Neck Down Geometry:
  • Reduces the sleeve's contact area with the casting.
  • Promotes directional solidification and clean knock-off after solidification.
  • Focuses feeding into critical hot spots while minimizing the feeder footprint.
• Insulating Composition:
  • Contains no exothermic components.
  • Retains heat efficiently, keeping feeder metal molten longer.
  • Produces zero smoke, fumes, or residue, ideal for enclosed or clean foundry environments.
