Pouring, Fluidity, Risers, Shrinkage And Other Defect In the previous section the fundamentals of the metal casting process, as the basic starting point for metal fabrication and part manufacture, were covered. Setup and design of a system to perform a casting operation was explained. Main topics were molds, patterns, cores, and the elements of a gating system. In this section…
Founding, the process of pouring molten metal into a cavity that has been molded according to a pattern of the desired shape. When the metal solidifies, the result is a casting—a metal object conforming to that shape. A great variety of metal objects are so molded at some point during their manufacture. The most common type of mold is made of sand and clay; ceramics, sand with cement, metals,…
To approach an ideal framework for designing a metal casting requires a detailed study of the contradictory requirements and identifying the best solution. The artifact’s designing, quality-benchmarking and cost-effective considerations play an important role to work out an ideal structure for metal casting. Advantages of defining framework: To design functionally stable cast products with production techniques using minimal development time.…
The wide range of casting alloys helps in selecting the most suitable and cost effective material that meets the requirements of a particular application. Each of these casting alloy has its own physical and mechanical properties. They also have their own casting characteristics, like: Weldability Machinability Corrosion resistance Heat treatment properties Did You Know Bronzes are unquestionably the most versatile…
Iron & steel casting is a phenomenon that takes place in a foundry, wherein molten iron is poured into a vessel or cast to create a desired shape. Cast materials are usually metals or cold setting materials such as concrete, epoxy, plaster, clay, ceramic or iron in which molten fluid is poured to get various shapes and sizes. Iron &…

This includes key trends, Metal Casting segmentation analysis, and recent industry statistics. The Metal Casting report further covers the extensive analysis of the upcoming progress of the Metal Casting market. The Metal Casting study presents different factors on…
The process of heat-treating metals on the industrial scale primarily serves to improve the overall properties of the metals required for their future use. Such metal properties can include toughness, hardness, ductility, machinability, refined grain structure, removal of residual stresses and an overall improvement in the wear resistance. The specific techniques used to both heat and cool metals are not…
Introduction Lightweight materials have become increasingly critical in the transportation manufacturing sectors, including aircraft, automobile, heavy truck, rail, ship, and defense manufacturing industries. Light metal and alloys possess high strength-to-weight ratios and low density, and are generally defined by low toxicity as opposed to heavy metals, except for beryllium. Lightweight metals consist of aluminum, beryllium, titanium, and magnesium alloys. Light…
Will alloy-inducing anti-corrosion agents make metal blasting a thing of the past? By Merrick Alpert Metal blasting (or sandblasting) has long been a go-to process to treat metal before the application of a surface material, such as an anti-corrosive agent. But as alloy-inducing anti-corrosion agents take the stage to compete with traditional barrier coatings, surface preparation will change. To understand why, we…
Sand casting is the most widely used metal casting process in manufacturing. Almost all casting metals can be sand cast. Sand castings can range in size from very small to extremely large. Some examples of items manufactured in modern industry by sand casting processes are engine blocks, machine tool bases, cylinder heads, pump housings, and valves, just to name a…
