Aluminum Titanate Ceramic Dosing Tube Overview

Aluminum titanate ceramic dosing tubes are precision-engineered components used in low-pressure die casting (LPDC) systems to accurately deliver molten aluminum from the holding furnace to the mold. Manufactured from aluminum titanate (Al₂TiO₅), these tubes provide excellent thermal shock resistance, low thermal conductivity, and outstanding non-wettability to molten metals. Their durability and stable performance in high-temperature environments ensure consistent dosing, extended service life, and reduced maintenance, making them essential for efficient and high-quality casting operations.
