5.3.1 Cast iron. The most important cast iron materials are GJL (gray cast iron), GJV (cast iron with vermicu-lar graphite), and GJS (cast iron with nodular graphite). Crankcases made of GJL are low cost; . stable with regard to deformations in both the cylinder surfaces and the main bearings; .
Sand Casting Process, Defects, Design
The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed.

Match Plate Pattern – EngineeringTechnology
Match Plate Pattern. A match plate pattern is a single piece casting pattern that is commonly used in sand casting. It consists of two opposing sides, the cope and the drag, each with a specific function in the casting process. The cope side has the positive form of the part to be cast, while the drag side has the negative form of the part.
