Casting Process

Consider the casting process at 645 B.C, the first traces of the Sand Molding was found. Now consider the state-of-the-art Electromagnetic casting process. Truly, the Casting process has traversed a long path and impacted human civilization for nearly five millennia. With technological advances, metal casting is playing a greater role in our everyday lives and is more essential than it…

Heat Treated Metals and Their Uses

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…

Properties and Production of Lightweight Metals

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…

Metal Mold Casting

Metal Mold Casting At least three families of molding and casting processes can be categorized as metal mold processes. These include diecasting (high-pressure diecasting), low-pressure permanent mold casting and permanent mold casting. Unlike sand casting processes, in which a mold is destroyed after pouring to remove the casting, permanent mold casting uses the mold repeatedly. Diecasting Diecasting is used to…

What’s the Difference Between Investment Casting and Sand Casting?

Though they have been refined through the ages, significant differences exist between the two methods used to make metal parts. Sand casting and investment casting are methods of creating metal parts by pouring molten metal into three-dimensional molds. Although methods are thousands of years old, both have been refined over the years to minimize the amount of metal used and…
