SpaceX’s foundry casting process for the Raptor engine manifold involves creating this crucial part, which distributes propellant to the engine’s combustion chambers. The manifold is made from a high-strength alloy to withstand the intense heat and pressure during operation. Precision casting ensures that the part is both durable and lightweight, essential for the rocket’s performance. The process starts with designing a mold using investment casting, where molten metal is poured into a ceramic
