The Low Pressure Foundry (LPF) process consists of vertically injecting liquid metal from a furnace placed under the mold through a tube. The molten aluminum is pushed up and down by a pressure of about 1 bar, forcing it to fill the cavity of the metal mold.
This process provides excellent internal mechanical properties because the filling is very controlled. The central feeding with the possibility to multiply the pouring attacks are particularly suitable for the production of sand-core and complex parts.
Saint Jean Industries uses this process as well for the mobility and energy industries in general. In the automotive industry, we find suspension/chassis parts, aluminum rims, and electric motor housings. And for the energy industries, SJI manufactures for example hydraulic pump casings, power plant casings.
