Splitt: 3 m³ x 1,6 t = 4,8 t.
Read MoreCasting is the process of pouring liquid metal into a mold, where it cools and solidifies. The casting process can produce everything from art pieces to engine parts. The shape is determined by the mold cavity, but something needs to shape the mold—that’s where the pattern comes in. Patterns are a model for the object to be cast.
