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 had finally dragged itself out…
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 rolls, wheels, cylinder blocks, liners,…
Water-soluble salts or electrolytes are just some of the mineral contaminates found in everyday tap water used by foundries across the U.S for their green sand systems. Bentonite is the main bonding compound of green sand systems, and fort it to have quality bonding, it first must be activated with the use of an agent. A good activating agent must…
The well-worn colloquialism, “Think Global, Act Local,” has been around for over 100 years. Different groups such as city planners, environmentalists, and even corporations have adopted the expression to encourage behavior and describe their engagement philosophy. The underlying message is that it is important to have a long term or big picture goal, but action needs to take place where…
The metalcasting industry is always moving ahead. Whether it’s how to pour the purest metal, produce components with as little scrap as possible, or plunge into additive manufacturing, when foundries look for ways to push into the future, they’re successful. Then it should not be a surprise that the industry is working to make sure there won’t be a shortage…
We know that casting is the process of pouring molten metal in a desired shaped cavity and allowing it to solidify. After the solidification we get the desired shaped object. Basic Operation of the casting process First we have to make a pattern Then the we have to melt the metal by applying heat pouring the metal into the mold and…
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…
Introduction: Since the evolution of mankind, man has used his intelligence and creative instinct to develop things that will reduce his labor. He shaped bowls, tools and weapons out of stones and wood which was naturally found in nature.With the passage of time he discovered other element in nature like gold, silver and copper which were readily available in nature in the…
Introduction: The discovery of metals was the stepping stone towards civilization. The metal are known to man form the pre biblical times and different civilizations used the metal to make products for religious, hunting, weapon, house hold and ornamental purpose. Now, man is dependent on metal for cooking to traveling. A separate department called the metallurgy studies the entire process of…
Alloys are metallic substances composed of a mixture or metallic solid solution of two or more metals. They can even be composed of a metal and another element which may be non-mettalic to produce an alloy. An alloy usually has different properties from the elements that it is composed of. A variation in the concentration and ratios of elements produces alloys…
