It is the first step in making most of the products.  \n• Steps:  \n-Making mould cavity  \n-Material is first liquefied by properly heating it in a suitable furnace.  \n-Liquid is poured into a prepared mould cavity  \n-allowed to solidify  \n-product is taken out of the mould cavity, trimmed and made to shape  \nWe should concentrate on the following for successful casting operation:  \n(i)Preparation of moulds of patterns  \n(ii)Melting and pouring of the liquefied metal  \n(iii)Solidification and further cooling to room temperature  \n(iv)Defects and inspection  \nR.Ganesh Narayanan, IITG  \nAdvantages  \n• Molten material can flow into very small sections so that intricate shapes can be made by this process. As a result, many other operations, such as machining, forging, and welding, can be minimized.  \n• Possible to cast practically any material: ferrous or non-ferrous.  \n• The necessary tools required for casting moulds are very simple and inexpensive. As a result, for production of a small lot, it is the ideal process.  \n• There are certain parts (like turbine blades) made from metals and alloys that can only be processed this way. Turbine blades: Fully casting + last machining.  \n• Size and weight of the product is not a limitation for the casting process.  \nNPTEL cRo.GuesohnNraauat, uIIig processes – I, Pradeep Kumar et al.  \nLimitations  \n• Dimensional accuracy and surface finish of the castings made by sand casting processes are a limitation to this technique.  \n• Many new casting processes have been developed which can take into consideration the aspects of dimensional accuracy and surface finish. Some of these processes are die casting process, investment casting process, vacuum-sealed moulding process, and shell moulding process.  \n• Metal casting is a labour intensive process  \n• Automation: a question  \nNPTELRc.GoasNoanraaanu, fIIturing processes – I, Pradeep Kumar et al.  \nTypical sand mould  \nMould Section and casting nomenclature  \nNPTEL course on Manufacturing processes –  \nI, Pradeep Kum","cbCaip6ppeO1c85T","https://ap.wps.com/l/cbCaip6ppeO1c85T","pdf",3600381,136,"English","# Introduction to manufacturing processes\n## Casting processes\n### Steps of casting\n### Focus areas for successful casting\n### Advantages\n### Limitations\n## Important casting terms\n## Mould Section and casting nomenclature","[{\"question\":\"What are the main steps in the metal casting process?\",\"answer\":\"The process involves making the mould cavity, melting the metal, pouring the molten metal into the mould, allowing it to solidify, and then taking the product out for trimming and shaping.\"},{\"question\":\"Which factors should be prioritized for successful casting operations?\",\"answer\":\"Key areas include preparing moulds and patterns, melting and pouring the liquefied metal, solidification and cooling to room temperature, and addressing defects and inspection.\"},{\"question\":\"What are the advantages of metal casting?\",\"answer\":\"Molten metal can fill very small sections for intricate shapes, many ferrous and non-ferrous materials can be cast, tools for moulds are simple and inexpensive, and certain components like turbine blades are suited to this route.\"}]","Metal casting processes - Introduction, moulding, defects and inspection | PDF",343]
