Are there any defects in the casting process?
Even though these high quality aspects are considered, defects are very much inherent in casting process. The main objective of the current review is to explain casting types and discuss the possible defects during the process of casting. The scope of the review also includes causes and remedies of casting defects.

How is a pattern used in the casting process?
In this process the material is first liquefied by proper heating and then this liquefied is poured into a previously prepared mould cavity where it is allowed to solidify and subsequently the product is taken out, cleaned and trimmed to the required shape. A pattern is the replica of the part to be cast and is use to prepare the mould cavity.
