Metal Casting

Metal Casting

What is Metal Casting? 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. The term ‘casting’ is also used to describe the part made by the casting process which […]

Sand Casting

What is Sand Casting? Sand casting is the most versatile among the manufacturing methods and gives the Engineers the freedom to design complex parts from unlimited number of metals and alloys. Sand casting is a manufacturing process where the molten metal is poured into the expendable sand mold cavity either by gravity or by force, where […]

Casting Process: Advantages and Limitations

Casting is also known as foundering, is the oldest manufacturing process in which liquid molten metal is poured into a perforated casting cavity of refractory material. Allow liquid metal to solidify, after solidification the casting metal can be taken out by breaking the mold. The casting process is used to produce components such as pistons, mill […]

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 […]

A Brief History of Metal Casting

A Brief History of Metal Casting

The story of metal casting begins some five and a half thousand years ago in Mesopotamia, the cradle of civilisation. The process, which involves pouring molten metal into a mould, was used by the Mesopotamians to create all manner of things including tools and weaponry, typically out of the copper — tin alloy, bronze. Civilisation […]

“No bake” Sand Castings

Sometimes, we believe that foundries are more or less similar. Reality demonstrates precisely the opposite. Dozens are the technical “distinctions” that allow differentiating a casting plant from another. precisely in the ambit of these differences, either small or big at first sight, we should research those technological advantages able to transform a process into efficient and up-to-date. […]

Green Sand Casting

Introduction: A commonly used form of sand casting, green sand casting gets its name because wet sand is used in the molding process. A variety of additives like pitch, cellulose and silica flour are used in this process. The aggregate of sand mold consist of mixture like silica, clay, water and other materials are taken for […]
