The low-pressure casting process
The low-pressure casting process is used for the production of high-quality light metal casting parts.
The metal melt is raised to the mould by pressurization via a riser pipe from a casting furnace, which is located below the metal mould. This method is characterized by a calm, turbulence-poor form filling, which leads to very low porosity and thus to very good mechanical properties of the castings.

- complex castings, such as engine blocks or cylinder heads (sand cores in the steel moulds)
