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…

EXPECTATIONS FOR GROWTH

As the American Foundry Society rolled out its annual economic forecast in January, the numbers were more encouraging than in recent years. AFS is projecting sales growth of 4.7% in 2018, followed by another 1.8% growth in 2019, for the overall market. Coming on the heels of an estimated 2.7 percent growth in 2017, the industry is looking at its…

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…

Improvement of the Lost Foam Casting Process

Improved Process Reduces Energy Use, Waste and Emissions, While Lowering Product Defects and Costs Casting is an energy-intensive manufacturing process within the metal casting and aluminum industries, requiring natural gas to melt aluminum and electricity to run equipment. The higher-than-acceptable faults and scrap rates in the lost foam casting process for the complex L61 engine previously resulted from the inability…

Foundry Equipment

Foundry Equipment include machines, tools and devices that are used in foundries and metal casting facilities to execute different functions and requirements. A wide range of foundry equipment and systems are available in the market that are used in applications, as varied as automation, mold, core and sand making, laboratory, safety and environmental conservation purposes, testing and inspection, cleaning and finishing,…
