Dense Ceramic Billet Casting Thimbles

Precision-manufactured dense ceramic thimbles specially designed for Hot Top and Direct Chill (DC) aluminum billet casting. Fabricated from high-purity refractory ceramics and fused silica materials, these solid thimbles offer outstanding mechanical strength, liquid aluminum non-wetting performance, and excellent dimensional stability. They effectively channel molten metal into crystallizer molds while resisting erosion and metal adhesion, ensuring superior billet skin quality and extended operational life.

Key Features:

• Solid High-Strength Structure: Resists mechanical impact, surface wear, and severe molten metal erosion during long casting runs.

• Superior Non-Wetting Performance: Chemically inert to liquid aluminum and its alloys, preventing metal buildup and ensuring effortless cleaning.

• Thermal Shock Resistance & Tight Tolerances: Maintains structural integrity and exact dimensional tolerances under rapid temperature cycles.
