Molding Sand: Constituents, Types and Properties

The general sources of receiving molding sands are the sea shores, rivers, lakes, deserts and granular elements of rocks. Molding sands can be classified mainly into two types namely natural or synthetic. Natural molding sands contains sufficient amount of binder material. Whereas synthetic molding sands are prepared artificially using basic sand molding constituents (silica sand in 85-91%, binder 6-11%, water or…

NINE GREEN SAND FACTS TO KNOW

The green sand casting process is the most widely-used process for casting ferrous and nonferrous metals. The process has evolved from a manually intensive operation to a highly mechanized and fully automated process that can produce more than 300 molds per hour. In terms of weight, complexity and alloy composition, a wide range of castings can be produced via green…

Sand Casting Process with Diagram

Sand casting: In sand casting which is also known as sand molded casting, an object is produced by sand mold. The process involves pouring of the molten metal in to the mold cavity. The molten metal is then cooled to the room temperature. The metal is solidified. After cooling, the metal object is separated from the mold.  Sand casting process…

Metal Casting

What is metal casting process? Metal casting is defined as the process in which molten metal is poured into a mold that contains a hollow cavity of a desired geometrical shape and allowed to cool down to form a solidified part. Term casting is also used to describe the part made by the casting process which dates back 6000 years. Historically it…

Types of Molds for Aluminum Casting

There are many types of molds for aluminum casting that are used in casting molten aluminum into different shapes and forms. Some molds are temporary, and others are permanent and can be used repeatedly. These same types of molds are also used for many different metals and alloys besides aluminum. Sand Casting Mold The oldest types of molds for aluminum…

Types of Casting Molds

Casting is a process in which a liquid is poured into a mold in order to produce a product. There are several types of molds that are used in the casting process. Some are temporary and are destroyed during the casting process. Others are permanent and are reused again and again. The type of mold chosen is usually based on…

Aluminum Casting Processes

Aluminum is one of the few metals that can be cast by all of the processes used in casting metals. These processes, in decreasing order of amount of aluminum casting, are: die casting, permanent mold casting, sand casting (green sand and dry sand), plaster casting, investment casting, and continuous casting. Other processes such as squeeze casting, and hot isostatic pressing…

Commercial Foundry

A Foundry deals with casting techniques, a process where the melted liquids are poured into moulds. This forms the first step towards manufacturing a product. Foundry Industry plays a vital role in the industrial development. Started as early as 3600 BC, the foundry industry has flourished very well and is likely to grow further. Castings are used for variety of…
