Bushing tubes are critical support components of the riser tube system in low-pressure aluminum casting (LPDC) systems, enabling the controlled transfer of molten metal from the ladle to the mold.

Designed to operate under high temperatures and continuous metal contact, it maintains system centering, minimizes wear, and supports sealing performance.

Process Function

In the LPDC process, liquid metal is conveyed to the mold via a bushing tube using controlled air pressure.

• Ensures stable operation of the riser tube system.

• It contributes to a centered and controlled flow of metal.

• Reduces the risk of leakage due to wear.

• It extends the lifespan of the system.
