Graphite Rings (Billet Casting & Industrial Seals)

High-purity isostatic graphite rings specifically engineered for Hot Top and AirSlip aluminum billet casting molds. Featuring inherent self-lubricating and non-wetting properties against molten aluminum, these graphite rings prevent metal sticking, eliminate surface tears, and deliver an exceptional billet skin finish. Their superior thermal conductivity ensures uniform heat transfer during solidification. Additionally, they serve as high-performance sealing and bearing rings in high-temperature vacuum and controlled-atmosphere furnaces.

Key Features:

• Self-Lubricating & Low Friction: Minimizes friction inside the mold during solidification to produce smooth, defect-free billet surfaces.

• Excellent Non-Wetting Performance: Chemically inert to molten aluminum and its alloys, resisting dross buildup and metal penetration.

• High Precision & Thermal Resistance: Precision-machined to micro-tolerances with high thermal conductivity and outstanding resistance to thermal shock.
