Metal casting is a modern process with ancient roots. In the metal casting process, the mold is formed by injecting molten metal into the mold cavity, where it is cooled and later removed from the mold. 

Metal casting is arguably the earliest and most influential industrial process in history. You can also find the best metal casting software via https://www.simulacionesyproyectos.com/software/flow-3d-cast-software-de-simulacion-de-fundicion/.

Patternmaking – A pattern is a replica of the exterior of the casting. Patterns are typically made of wood, metal, plastic, or plaster. Patternmaking is incredibly important for industrial part-making, where precise calculations are needed to make pieces fit and work together.

Coremaking – If casting is hollow, an additional piece of sand or metal (called a core) shapes the internal form to make it hollow. Cores are typically strong yet collapsible so they can be easily removed from the finished casting.

Molding – To visualize the metal casting process so far, imagine yourself walking on the beach toward the ocean. Look at the footprint you leave behind in the wet sand. Your foot would be the core, and the impression left in the sand is a mold of your foot. 

Molding is a multistep process that will form a cast around the pattern using molding sand. In casting, a mold is contained in a frame called a flask. Greensand, or molding sand, is packed into the flask around the pattern.
