Highly Exothermic Open Sleeves – CylindricalType are specialized foundry consumables used in metal casting processes. These sleeves are part of the "feeder system" and play a critical role in compensating for shrinkage during the solidification of castings

Key Features:

• Cylindrical Shape: Designed for open riser systems; easy to position and ideal for vertical feeding applications
• Highly Exothermic: Generates intense heat upon metal contact, delaying solidification in the feeder and thus:
• Improves metal flow to the casting.
• Increases feeding efficiency.
• Material: A mix of insulating and exothermic compounds that form a hot-top condition
• Sizes: Available in various internal diameters and heights depending on casting requirements
