Sand Casting - an overview ScienceDirect Topics

Sand castings are less common in structural applications, due to their slower cooling rate and generally coarser microstructure. However, in certain applications, such as the cast 356-T6 nodes for the Ford GT spaceframe, need for specific geometries at low production volumes requires the use of sand castings.

Definition and Characteristics of Small Batch Production ...

Small batch production refers to the production of special products which are basically required in small batches. Single-piece small-batch production is a typical make-to-order (MTO), which has similar characteristics with single-piece production and is customarily called "single-piece small-batch production". Therefore, in a sense, "single ...

How concrete is made - material, manufacture, making,

The manufacture of concrete is fairly simple. First, the cement (usually Portland cement) is prepared. Next, the other ingredients—aggregates (such as sand or gravel), admixtures (chemical additives), any necessary fibers, and water—are mixed together with the cement to form concrete. The concrete is then shipped to the work site and placed ...
