The AlTi Stopper–Nozzle system is a high-performance flow control component that enables precise and controlled management of liquid metal flow in low-pressure aluminum casting (LPDC) processes.

It regulates the safe and stable transfer of liquid metal from the crucible to the mold, ensuring leak-proofness and process reliability during flow interruption and start-up operations.

Process Function

In LPDC systems, metal flow is controlled by pressure. Stopper-nozzle system:

• It starts and stops the flow of metal.

• It contributes to the controlled progression of the flow rate.

• Minimizes turbulence.

• Reduces the risk of oxidation and air mixing.

• It directly affects casting quality.

Technical Advantages

• Thermal shock resistance

• Abrasion-resistant reinforced structure.

• Leakproof and precision tolerance design.

• Long service life

Process Additives

• Stable and controlled filling.

• Low porosity risk

• More homogeneous metal flow.

• Reduced maintenance and downtime.

• Increased system reliability
