High-Performance Ceramic Riser Tubes for Demanding Casting Applications

Ceramic riser tubes are critical components used in low-pressure die casting and molten metal transfer systems. Positioned between the furnace and the mold, they transport molten aluminum or other non-ferrous alloys while maintaining consistent flow and minimizing heat loss. Compared with conventional metal tubes, advanced ceramic riser tubes offer superior resistance to thermal shock, oxidation, and molten metal corrosion, resulting in significantly longer operational life.

Manufactured from high-strength silicon nitride-based ceramics, Semicorex Ceramic Riser Tubes combine excellent fracture toughness with low thermal expansion. These characteristics enable the tubes to maintain dimensional stability during repeated heating and cooling cycles, reducing the risk of cracking and unexpected downtime.
