Casting process enjoys certain advantages vis-a-vis other shaping processes such as forging, welding, stamping, rolling, extruding, etc. The reasons for the success of the casting process are: Owing to physical properties, some metals can only be cast since they cannot be re-modelled into bars, rods, plates or other shapes. It's a process highly adaptable to the requirements of mass production.…
There are many types of molds for aluminum casting that are used in casting molten aluminum into different shapes and forms. Some molds are temporary, and others are permanent and can be used repeatedly. These same types of molds are also used for many different metals and alloys besides aluminum. Sand Casting Mold The oldest types of molds for aluminum…
Casting is a process in which a liquid is poured into a mold in order to produce a product. There are several types of molds that are used in the casting process. Some are temporary and are destroyed during the casting process. Others are permanent and are reused again and again. The type of mold chosen is usually based on…
There are a number of different types of metals which are acceptable for welding. It is important to know how to weld specific welding metal types so that you have the correct welding equipment on hand to properly get the job done. Welding Aluminum Welding aluminum requires high power welding and very clean oxide-free surfaces. Cleaning a surface to be…
Building with metal is great — it’s strong, versatile, and looks cool. When you’re getting started on a metal project, the first step is determining what type of material will work best. For most projects, steel, stainless steel, aluminum, and copper have a good range of properties and are easily available at a reasonable price. Although many other alloys and metals…
Alloys are metallic substances composed of a mixture or metallic solid solution of two or more metals. They can even be composed of a metal and another element which may be non-mettalic to produce an alloy. An alloy usually has different properties from the elements that it is composed of. A variation in the concentration and ratios of elements produces 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…
Aluminum is one of the few metals that can be cast by all of the processes used in casting metals. These processes, in decreasing order of amount of aluminum casting, are: die casting, permanent mold casting, sand casting (green sand and dry sand), plaster casting, investment casting, and continuous casting. Other processes such as squeeze casting, and hot isostatic pressing…
Introduction to Metal Casting: From ages immemorial, metal has been a faithful companion of the human in peace or in war. To refine the metal that is unearthed from the core of the earth and to melt and shape them a variety of techniques has been developed, which is generally termed as castings. With the passage of time casting has progressed…
Foundry is a factory engaged in production both ferrous and non-ferrous metal castings. The type foundries specialize in casting metal fonts primarily used in printing industry. Today technology has given way to e-foundry, which is a type foundry that develops digital fonts with the aid of electronic tool. Foundry Process-Step-by-Step Instructions The entire foundry process can be summarized in nine…
