Important Facts You Need to Know About Iron Casting Buying an iron casting can be a very challenging task but this does not mean that it should be difficult to get the right cast that will give you quality results. There are many metal casting manufactures and all of them use different methods and foundry procedures in producing their casts. As a result, the quality of iron cast will vary depending on the manufacturer and the process used to produce it. If you know what to look for, then you should be able to get a cast of the right quality.
You should first consider the quality of the foundry producing the cast. Different manufacturers employ different foundry practices and these have a direct impact on the quality of the end product. You also have to look into the carbon concentration of the iron cast. Carbon concentration has a direct impact on the strength of the cast. An ideal concentration should be between 2.5% and 4.0% and any slight variations can greatly affect the overall strength of the cast. There are different methods of casting used to produce different products. For instance, shell molding is used to produce bigger casts and it has a good finishing as compared to the other methods of casting. For small and medium sized products, the green sand molding is used while for pipes and cylindrical products the centrifugal casting is employed. In order to get a high quality casting, you should look for a combination of a foundry with good practices and which utilizes good casting methods. Iron castings are used in different fields including machining, agriculture and automotive industries. Some products made from casting iron are pumping house casings, the dynamometer and compressors. It is also worth to note that there are several types of cast e.g. malleable castings, ductile castings and alloy castings. All these are ideal for various uses and you should tell the iron castings manufacturer of the exact type you prefer. While dealing with iron castings, there are certain scientific terms used to describe the various aspects of the product which you need to be familiar with. You should understand the meaning of Brenell hardness number, modulus of elasticity and the tensile strength so that you have a better insight on the properties of the cast.
