Types of Casting Molds

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…

Metal Basics: A Beginner’s Intro to Choosing the Right Material

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…

Uses of Alloys

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…

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 Casting Processes

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…

Casting

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…

Ferrous metals are highly versatile. Read this article to learn about their applications and advantages and disadvantages of ferrous metals Have you noticed how some materials rust over…

Foundries

Introduction: A foundry is where the elaborate metal casting process takes place. A metal foundry may specialize in making one particular item or a variety of products using different alloys. Based on the production requirement, there are small foundries that employ few people and large industrial foundries that employ thousands of workers. History: Foundry operations of the present day is an outcome of…

Definition

Casting is a method where a solid material is dissolved, heated to suitable temperature (generally treated to change its chemical structure), and is then added into a mold or cavity, which keeps it in a proper form during solidification. As a result, in just one step, complex or simple designs can be created from any material that can be dissolved.…
