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 rolls, wheels, cylinder blocks, liners,…

Does Water Quality Affect Green Sand Properties?

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…

U.S. Metal Casting at A Glance

We break down the U.S. metalcasting industry by metal, process, state, and value-added services. Using data gathered from a nationwide survey of the U.S. metal casters, Modern Casting can paint a picture of the industry in 2017. The data was compiled from a survey of 1,633 domestic metal casting facilities, 84% if the country's estimated 1,949 plants in 2017. Following is a…

THINK GLOBAL, ACT LOCAL

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…

EMPLOYMENT LAWS TO KNOW AND UNDERSTAND

Manufactured products, particularly foundry products, cannot reach their intended market without the labor of humans. That means there is always an opportunity for issues related to employment and labor to come to the fore and perhaps steal attention away from the critical operational issues of the foundry in favor of employment or labor issues. Indeed, manufacturers are often prime targets…

LEARNING THE CRAFT

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…

Manufacturing: Metal Casting

Introduction Casting is a manufacturing process where a solid is melted, heated to proper temperature (sometimes treated to modify its chemical composition), and is then poured into a cavity or mold, which contains it in the proper shape during solidification. Thus, in a single step, simple or complex shapes can be made from any metal that can be melted. The…

A Complete Guide to Steps Involved in Casting Process

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…

Different Parts of Sand Mold- Features

Cope and drag in Sand Mold : Cope and Drag are the two parts of the casting flask. Cope is the upper part and drag is the lower part. Even if the casting process is flaskless , the same terms are used for the upper ans lower parts. Generally the flask is made of wood or metal. It contains molding…

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…
