Sand Casting Process

Sand Casting Process

In sand casting, the molten metal is poured into the cavity, which has a pattern made of wood or metal. The patterns is a exact replica of the shape that the metal is to casted in. Molten metal in introduced into the cavity in the shape of the casting to be made. When the cast solidifies the mold is broken …

Sand Casting

Sand Casting

Sand casting is a casting process where the molten metal is poured into a mold made of sand. There are various types of sand castings like Green-sand molding, air set sand casting, dry sand molding and the lost form method. Sand casting is the most commonly used Casting Process because of the cost effectiveness of the process and the east availability …

Sand Casting Applications

Sand Casting Applications

Sand Casting Applications : Sand casting is extensively used, for cast iron and steel parts of medium and large size where surface smoothness and dimensional precision are the main concerns. Sand casting is also used to make large parts in material like bronze, brass, aluminum, etc. Also used for casting sculptures which can have a certain amount of rough surface finish.

Types of Sand Used in Casting

Types of Sand Used in Casting

The Dry Sand The drying sand used in foundry industries, The dry sand from which all free or uncombined moisture has been removed usually by heating in a dry oven or stove sand dry practice is used mainly for the production of large castings or where dimensional accuracy and soundness are periodically importance.The how to dry sand mould may be completely dried before the …

Grey Iron Casting Process

Grey Iron Casting Process

Several molding processes are used to produce gray iron castings. Some of these have a marked influence on the structure and properties of the resulting casting. The selection of a particular process depends on a number of factors, and the design of the casting has much to do with it. The processes using sand as the mold media have a …

What is Sand Casting

What is Sand Casting

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term “sand casting” can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 70% of all metal castings are produced via sand casting process.

Ferrous Casting

Cast Iron Process

Cast Iron Process

Basic process There are six steps in this process: 1.Place a pattern in sand to create a mold. 2.Incorporate the pattern and sand in a gating system. 3.Remove the pattern. 4.Fill the mold cavity with molten metal. 5.Allow the metal to cool. 6.Break away the sand mold and remove the casting.

Cast Iron Chemical Composition

Cast Iron Chemical Composition

Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. what is cast iron used for microstructure of grey cast iron Grey cast iron is characterised by its graphitic microstructure, which causes fractures of the material to have a grey appearance. It is the most commonly used cast iron and the most widely used …

Sand Casting Defects

Sand Casting Defects

Production of castings involves a large number of steps including casting design, pattern making, moulding, melting, pouring, shake out, fettling, inspection and finishing. It is not uncommon for one or more of these steps to be performed unsatisfactorily due to use of defective material or equipment, carelessness of the operator or lack of skill. Such unsatisfactory operations result in a …

Cast Iron Composition

Cast Iron Composition

Cast iron is a group of iron-carbon alloys with a carbon content greater than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical …
