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…

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,…

Lost Foam Casting

Lost Foam Casting in Aluminium is very similar to Investment Casting (e.g. as used by Jewellers and Dentists) except the finished casting is the result of evaporating Polystyrene out of the mould rather than melting wax. The process lends itself to complex and sculptural shapes which would be difficult to remove from a mould. By its nature, the process can leave a rough surface (reflecting the surface of a…

Manufacturing Processes – Green Sand Molding

Green Sand Casting

Green Sand Molding Green sand is by far the most diversified molding method used in current metalcasting operations. The green sand process utilizes a mold made of compressed or compacted moist sand packed around a wood or metal pattern. The term "green" denotes the presence of moisture in the molding sand, and indicates that the mold is not baked or…

How Investment Casting Works

Investment casting process steps Investment casting has been creating near net shape products successfully in various forms for thousands of years. Although the introduction of new materials and manufacturing techniques in the last few years has led to some changes and improvements, the investment casting process steps have largely remained unchanged. In general, investment casting or sometimes referred to as lost wax casting can be summarized…

Investment Casting

What is Investment casting? In investment casting, a wax or suitable polymer pattern is coated by dipping into the refractory material slurry. Once the refractory material coating is hardened then this dipping process is repeated several times to increase the coating thickness and its strength. Once the final coating is hardened the wax is melted out and molten metal is poured…

Alloys

Almost every material we could ever want is lurking somewhere in the planet beneath our feet. From the gold we wear as jewelry to the oil that powers our cars, Earth's storehouse of amazing materials can supply virtually every need. Chemical elements are the basic building blocks from which all the materials inside Earth are made. There are 90 or so naturally…
