Sand Casting by NINGBO RUICAN MACHINERY COMPANY

Sand casting, probably the most extensively utilized casting process, utilizes expendable sand molds to type complex metal components that could be produced of nearly any alloy. Because the sand mold have to be destroyed to be able to remove the portion, known as the casting, Grey Iron Casting typically has a low production price. The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted within the furnace after which ladled and poured into the cavity of the sand mold, that is formed by the pattern. The sand mold separates along a parting line and the solidified casting may be removed. The measures within this process are described in greater detail within the next section. In sand casting, the principal piece of equipment may be the mold, which includes numerous elements. The mold is divided into two halves - the cope (upper half) as well as the drag (bottom half), which meet along a parting line. Both mold halves are contained inside a box, named a flask, which itself is divided along this parting line. The mold cavity is formed by packing sand about the pattern in every half from the flask. The sand may be packed by hand, but machines that use stress or influence make sure even packing on the sand and need far much less time, as a result escalating the production price. After the sand has been packed and also the pattern is removed, a cavity will remain that forms the external shape on the casting. Some internal surfaces in the casting could be formed by cores.

Sand casting is used to create a wide number of metal components with complicated geometries. These parts can differ drastically in size and weight, ranging from a couple ounces to many tons. Some smaller sized sand cast parts incorporate components as gears, pulleys, crankshafts, connecting rods, and propellers. Bigger applications consist of housings for massive equipment and heavy machine bases. Sand casting can also be frequent in generating automobile elements, like engine blocks, engine manifolds, cylinder heads, and transmission situations.

Sand casting is able to use of practically any alloy. An advantage of sand casting will be the capacity to cast materials with higher melting temperatures, which includes steel, nickel, and titanium. The 4 most common materials which can be utilised in sand casting are shown beneath, along with their melting temperatures

Materials Melting temperature

Aluminum alloys 1220 °F (660 °C)

Brass alloys 1980 °F (1082 °C)

Cast iron 1990-2300 °F (1088-1260 °C)

Cast steel 2500 °F (1371 °C)

The material cost for sand casting involves the price in the metal, melting the metal, the mold sand, and the core sand. The price of the metal is determined by the weight from the part, calculated from part volume and material density, as well the unit cost of the material. The melting expense will also be greater to get a larger component weight and is influenced by the material, as some components are more expensive to melt. However, the melting price in normally insignificant in comparison with the metal expense. The quantity of mold sand which is employed, and therefore the price, is also proportional to the weight in the component. Lastly, the cost of the core sand is determined by the quantity and size on the cores utilised to cast the portion.

Sand casting process advantages

Can produce very large parts

Can form complex shapes

Many material options

Low tooling and equipment cost

Scrap can be recycled
