Precision Castings Widely Used in Automotive Industry
2016-04-07

Generally speaking, the process of Precision Casting has always been used in the iron industry to make iron products according to requirements. Besides, the introduction of automobiles in the early part of 20th century resulted in a rapid increase of iron consumption in automotive companies all over the world. Recently, the automobile companies still remain as the single largest consumer of metal castings. In fact, automotive castings are a bit different from other iron castings. As the products of these casting forms important parts of a vehicle, the casting has to e perfect and flawless.

Grey iron castings: It is the most commonly found cast iron and is also one of the most widely used materials for casting. Graphite is generally present in this cast thus giving it a distinct grey color. It is mainly used in products with non critical tensile strength like pump housings, electrical boxes, decorative items and valve bodies. It facilitates high level of thermal conduction for which it is also used in making cookware and rotors for brakes. Usually, most grey iron castings have 1 to 3 percent of silicon and 2.5 to 4 percent of carbon. Silicon, being a reliable graphite stabilizing agent, is widely used in grey iron casting.

Ductile iron castings: This type of cast iron was introduced in 1943 and since then it has been widely used by different industrial sectors including the automobile sector. The main advantage of this casting is that it is not brittle and is able to withstand stress for a long period of time. Several materials are mixed with iron to form ductile casting. The main materials that are used for this purpose are carbon, silicon, manganese, magnesium, phosphorus and sulfur. Carbon and silicon are, however, present in the highest concentration.

As we mentioned above, castings are widely used in automobile sector and are used to produce a number of automotive components. These components are manufactured by placing the molten iron in moulds specifically designed according to the requirements of the automobile industry. The cast products are then taken out of the moulds and are fitted in the automobiles. Nowadays, almost all equipments in an automobile are made of cast metals.

There are many companies that are involved in the production and distribution of cast metals. As the casting process is quite intricate one, it needs to be completed perfectly in order make the products flawless. Clients in need of such products should always take the help of professional experts who can give effective suggestions regarding the products. Quality check is absolutely essential before buying such product because compromising with the quality may result in the lack of the desired result.
