Sand casting is a form of pouring in an iron mill, using sand as a cast. General

To produce a cast, a three-dimensional impression (in the form of a cavity) of the final product is required in a mold. This uses a material that is much easier to handle than the metal. It is made of wood, for example.

For complex models, certain cores are used to obtain, for example, a cavity in the object. This model is embedded into two (or more) integrated cabinet boxes in light adhesive sand. This sand consists of quartz sand (the base), clay and water. The last two elements ensure the bonding and plasticity of the mold. By adding a small amount of graphite powder, the surface quality of the cast iron cast iron castings can be improved. This gives a typical black color. Core sand requires higher strength, fire resistance and gas permeability than mold sand.

When the mold cabinets are separated and the model is taken out, a precise depiction of the model remains known as a mold cavity in the sand. This is assembled after the weather of the molded castings with molten metal castings. When it is solidified, the sand is removed and the metal "cast" remains in the correct shape. In order to keep the cores of, for example, engine blocks in place and to remove the core's core after casting, round openings have been recessed into the casting, which will later be sealed with metal covers, so-called freeze caps.

Due to the seam between the two sandy forms, there is almost always a broom on the product. Features
