Exothermic Oval Open Sleeves widely used in foundries to improve feeding efficiency and casting integrity for ferrous metals

Key Features:

• Open Top Design
  • Ideal for vertical feeding setups in cope or drag molds.
• Exothermic Reaction:
  • When molten metal enters the sleeve, the exothermic reaction generates intense heat.
  • This heat delays solidification of the feeder, ensuring longer feeding time into the casting.
  • Improves directional solidification and reduces shrinkage cavities.
• Optional Collars or Breaker Cores:
  • Can include collars for added height and breaker cores for easy riser removal.
