Metal Casting Process topics include: Pattern allowances, heating and pouring, hot and cold chamber die casting. Metal casting is a manufacturing process that involves pouring molten metal into a mold to create a 3D metal part.  The process includes the following steps: Patternmaking: Create a model of the final part to be made Molding: Design and make a mold using the pattern Melting and pouring the metal: Pour hot liquid metal into the mold Finishing: Extracting the solid metal casting and finishing the piece  The mold contains a hollow cavity of the desired geometrical shape.
